eyewear sizing

Will a Sawfly regular size lens fit into a large Sawfly frame? Will a StingerHawk regular size lens fit into a large StingerHawk frame?

The Sawfly small and regular size lenses are only compatible with the regular size Sawfly frame. The size large lenses are only compatible with the size large frame. The same goes for StingerHawk lenses and frames—small and regular fit in regular size frames and large frames fit with large frames.

How do I know what size Sawfly I own?

There are several ways to determine the lens size that you have. Remove the nosepiece from your eyewear; look at the curve on the lens where the nosepiece fits: On the small and regular sized Sawfly lens, there are two sets of notches—one at the bottom and one at the center of the curve. On the large size Sawfly there is only one set of notches. You can distinguish between regular and small using the markings on the lens. On the inside of the lens, above the nosepiece, laser etched next to the Revision logo and the Z87 mark, the small Sawfly lens has a “+SH”; the regular has only “+S.” For further assistance, reference our Sawfly Lens Size Guide, found here.

How do I know what size Sawfly or StingerHawk I need?

Our Sawfly Eyewear System comes in sizes small, regular, and large. We recommend the size small to people who have a hat size between 6 1/2 and 6 7/8. The regular is recommended for people who have a hat size between 6 3/4 and 7 3/8 and the large is recommended for people with a hat size between 7 1/4 and 7 1/2. To view our Sawfly Sizing Guideline, click here. Our StingerHawk Eyewear System comes in sizes regular and large. We recommend the size regular to people who have a hat size between 6 3/4 and 7 1/2. The large is recommended for people who have a hat size between 7 1/8 and 7 7/8. To view our StingerHawk Sizing Guideline, click here.


eyewear product care and maintenance

What is the best way to clean my lenses?

Besides using our lens cleaner, we also recommend using a diluted solution of warm water and dish soap. Wash, rinse and let air dry.

Is there anything I can do to prevent my lenses from fogging?

Revision lenses are manufactured with a coating that helps fight both fogging and scratching. However, another great tool is our Anti-Fog Cloths. The Revision Anti-Fog Cloths use advanced nanotechnology to help keep the lenses from fogging up. They are sold in a carton of 3 on our website and each cloth can be reused up to 25 times.



Do you recommend any opticians?

We cannot recommend any specific opticians. However, we do have a form to help your optician fill your prescription and cut the lenses in accordance with the shape and contours of your desired eyewear product.

Does the $99.99 cost to fill the carrier include the carrier itself or is that additional?

The $99.99 USD cost includes the prescription lenses as well as the Rx carrier vision correction system itself. You will receive your order with the lenses already in the carrier. The Rx Carrier and Rx Carrier Connector System are the same price.

Does the military or law enforcement discount apply to prescriptions?

We do offer a discounted price on our Rx carriers to military and law enforcement personnel. The discounted price is $69.99 USD (+$9.95 S&H). We also offer discounted prices on the Hellfly prescriptions, but those vary depending on which lens/frame combination you purchase. When filling out the Rx order form, please make a note anywhere on the form that you would like to take advantage of the military/LE discount and we will be sure to apply it to your order.

Can I wear your eyewear over my eyeglasses?

We recommend that you do NOT wear eyeglasses under your Revision Eyepro. We go to great lengths to ensure the ballistic capabilities of our eyewear. Wearing regular eyeglasses under your Revision eyewear puts your safety at risk. Because, while Revision frames and lenses are able to withstand ballistic impact, your regular eyeglasses very probably cannot, and could shatter, potentially causing serious eye injury, blindness or even death. Please see the information above regarding our Revision prescription options.

How do I fill my Rx Carrier with my prescription?

We suggest the following three options:

  1. Have your prescription filled by any licensed optician. To do this you will need to purchase one of the Rx Carrier Kits from one of our licensed dealers or directly through Revision, and take the frame to your optician for fulfillment.
  2. Have your prescription filled by Revision. Simply complete the Rx Fulfillment Form and fax it back to us. The $99.99 USD flat rate includes the prescription & Carrier. It takes approximately 2 weeks from the time we receive your order until it is shipped.
  3. If you are active military, please visit your on-base optometry clinic, where you can obtain a filled Rx Carrier through the SERTS Program. Active, Reserve, and National Guard members can also have their prescription filled for free through the Naval Ophthalmic Support & Training Activity (NOSTRA). To learn more, click here.

What are your prescription options, and what are their limitations?

The Rx Carrier can accommodate a single vision prescription that is +11 through -11, and is compatible with our Sawfly Spectacle, StingerHawk Spectacle, Desert Locust Goggle, Bullet Ant Goggle, and Wolfspider Goggle. The Hellfly Ballistic Sunglasses can accommodate a single vision prescription that is +1 through -4.

Does the SnowHawk Cold Weather System have a different Rx Carrier System?

Yes. The SnowHawk Rx Carrier Connector System is similar to the Rx Carrier Connector System used for other Revision Goggles, but the connector piece is slightly longer and thicker to suit the particular shape of the SnowHawk Goggle.

What’s the difference between an Rx Carrier and an Rx Carrier Connector System?

The regular Rx Carrier is compatible with StingerHawk and Sawfly spectacles. This Rx Carrier is simply the frame with the prescription lenses and this connects directly to the nosepiece of the spectacles as is. The Rx Carrier Connector System is comprised of the regular frame with the prescription lenses plus a detachable connector piece that enables attachment to the nosepiece. The Rx Carrier Connector System is used with Desert Locust Goggles, Wolfspider Goggles, and Asian Locust Goggles.

Are you able to fill a bifocal prescription?

We are unable to fill a bifocal lens as you would need to be onsite for the measurements that these prescriptions require. We are able to fill a single vision prescription only. You can certainly purchase the blank prescription carrier frame and bring it to your local optometrist where they can take your measurements and fill your bifocal lens prescription on site. The cost to purchase the blank prescription carrier would be $24.99 USD (+S/H). This can be purchased directly from our website,, or by contacting customer service toll free at 1-800-383-6049.


eyewear miscellaneous

What is the difference between ShadowStrike Sunglasses and Hellfly Sunglasses?

Both ShadowStrike and Hellfly Sunglasses are dual lens ballistic eyewear that provide UV-A-B-C protection. However, beyond stylistic differences, there are several distinctions between the two lines. ShadowStrike Sunglasses have increased ballistic capabilities and feature Revision’s OcuMax™ Plus anti-fog and scratch-resistant coating. Unlike Hellfly, ShadowStrike Sunglasses also have interchangeable lenses and, like Revision’s Sawfly and StingerHawk spectacles, can be connected to a strap (which comes included in ShadowStrike kits). Hellfly Sunglasses have overmolded (rubber) arms, whereas ShadowStrike has low-profile arms designed for use with comms systems and helmets. Currently, ShadowStrike lenses are not Rx compatible, whereas Hellfly Sunglasses can be fitted with prescription lenses upon request.

How do I change out ShadowStrike lenses?

ShadowStrike Sunglasses feature a unique nosepiece mechanism that makes changing out the dual lenses fast and easy. Follow the step-by-step instruction on this guide

Does Revision eyewear have UV protection?

Yes. All of Revision’s spectacles and goggles have 100% UV-A, UV-B, and UV-C protection.

Does the balaclava come in different colors/different camouflage?

The balaclava standard offering is in black and white. Revision can investigate different colors/camouflage should the quantity warrant it. Please email for more information.

What is the maximum range in temperature that the SnowHawk Cold Weather Goggle System can sustain?

We test our products per the military standard (MIL-PRF-32432(GL)) which requires no loss of function after exposure at -60F and 160F.

Are there different types of lenses for low-light light?

We offer a variety of lens tints for all of our eyewear products. Most of our eyewear systems have lens options that are specifically designed for low-light conditions, specifically, yellow high-contract lenses and vermillion high-contrast lenses.

Can I purchase the SnowHawk balaclava separately?

Yes, the SnowHawk balaclava with Magnetic Facemask Integration can be purchased on its own by contacting customer support to place an order.

How do I remove the MFI Carrier from the MFI Balaclava so I can wash it?

If you look carefully at the inside of the mask, you will see two small holes on each side that you can carefully slide the carrier out of. We recommend that you machine wash in cold water using Permanent Press Cycle or hand wash using a mild detergent that does not contain optical brighteners or fabric softeners and rinse completely. Do not use chlorine bleach. Hang to dry.

How do I know if the balaclava is magnetically attached to the goggle?

When attaching the magnetic strip of the balaclava to the bottom of the goggle frame, an audible click can be heard once the magnets have engaged.

How does the balaclava connect to the SnowHawk Cold Weather Goggle?

The SnowHawk Cold Weather Goggle utilizes Anon’s proprietary MFI Technology (Magnetic Facemask Integration). The four magnetic connection points make sealing your balaclava to your goggles a snap, and provides a long-lasting connection. The reinforced perforated O2 vents keep you fully covered and fog-free.

Do you sell Desert Locust Thermal Lenses?

We do not currently sell thermal lenses for the Desert Locust Goggle System. Please contact Customer Care if you have additional questions about Desert Locust Lenses or thermal lenses.

What is APEL UPLC?

The Universal Prescription Lens Carrier (UPLC) list is a subset of the APEL list. UPLC lenses offer rims that hold prescription lenses in the protective eyewear. Revision’s Bullet Ant, Wolfspider, and Desert Locust goggles, as well as Sawfly and StingerHawk spectacles are all APEL UPLC compatible.

What is APEL?

The Authorized Protective Eyewear List (APEL) is an exclusive Qualified Products List (QPL) of manufacturers who have had their products examined and tested and who have satisfied all applicable qualification requirements; specifically, with regard to APEL, all the listed eyewear meets or exceeds Army standards for ballistic protection. Revision’s Desert Locust, Bullet Ant, Wolfspider, and Exoshield goggles, as well as StingerHawk and Sawfly spectacles, are on the listed on APEL.

What protective standards does Revision eyewear meet?

Revision’s spectacles and goggles are tested to a number of international protective standards: principally, ANSI Z80; ANSI Z87.1-2010; MIL-PRF-32432, clause; MIL-PRF-32432, clause, and EN166. Each has its own set of controlled tests that designate the level of protection users can expect when using the eyewear in the field. All of Revision’s spectacles and goggles meet ANSI Z87.1-2010. This standard covers a wider range of protective eyewear, including eyewear used for everyday handywork and construction, sunglasses with protective lenses, and eyewear used in certain military and tactical situations. The MIL-PRF standards are set by the U.S. military; these certify eyewear for use in the harsh and extreme conditions of the battlefield. Therefore, MIL-PRF standards are more stringent. MIL-PRF also draws a distinction between protective spectacles and protective goggles.

Typically, protective goggles offer greater protection than spectacles, however, Revision’s Sawfly spectacle system and StingerHawk system meet or exceed both MIL-PRF-32432, clause for spectacles and MIL-PRF-32432, clause for goggles. Additionally, for eyewear used outside the U.S., Revision tests against EN 166 to capture testing measures not covered by U.S. testing standards but required in other regions of the world. Specific protection level information can be found on the specs sheet for each eyewear product on Revision’s site.


head systems product care and maintenance

How do I maintain and clean my helmet?

It is important to routinely conduct a visual inspection of all head system components before and after each use. The visual inspection helps to identify wear and tear of fabric material or sewn components and cracks, scratches, holes, or deformation. Helmets and head subsystem components that have been damaged by impact or general wear must be replaced as soon as possible as they will no longer offer the same level of protection.

Clean your helmet shell, chinstrap, suspension system from dust and dirt with mild soap and water on a regular basis. Use a soft brush to clean delicate parts. Allow time to air dry your equipment after cleaning. After your head subsystem has been exposed to water, rain, or other wet conditions, allow the system to dry in open air (under cover) before storage.


head systems compatibility

Are the Caiman visors and mandible guards interchangeable between the Caiman Bump, Caiman Hybrid, and Caiman Ballistic helmets?


Which NVG mounts is the Caiman NVG Arm Visor compatible with?

The Caiman NVG Arm Visor attaches to most NVG mounts that accept a dove-tail interface.

Can the M50 gas mask be worn with the Batlskin Head Protection System?

When wearing an ACH helmet fitted with Revision’s Front Mount, it is possible to wear the M50 CBRN mask with the Visor closed. The Mandible Guard is not designed to be worn with the CBRN mask in use. Watch the video.

Are the ARC rails compatible with Revision helmets?

Revision's High Cut Helmets accommodate the Batlskin Interlocking and Standalone Long Rails that allow for easy installation of cameras, flashlight, and other head borne accessories onto helmets. Revision also has designed a rail-ready cut of the ACH-shaped helmet that is meant to work with current ARC rail systems available upon request. Please contact Customer Service at

Is the Batlskin Head Protection System compatible with NVGs?

Yes. The Batlskin Front Mount receiver component accommodates the Batlskin Viper Visor as well as widely used NVGs, such as the PVS-7 and PVS-14. If using other types of NVGs, such as ENVG III NVGs, the receiver component can be swapped for the upgradable receiver that is included with these NVGs. When NVGs are worn, we recommend using clear ballistic eye protection such as the Sawfly. Watch the video.

Are Viper head system components compatible with all Viper helmets? Are Cobra head system components only compatible with the Cobra helmet? Are Caiman head system components only compatible with Caiman helmets?

The Batlskin Viper Head System components—Front Mount, Mandible Guard, Visor, and side rails—have been designed to work with:

  • Revision's Viper P4 (Composite) helmets
  • Revision’s Viper P2 (Composite) helmets
  • Revision’s Viper A3 (Aramid) helmets
  • Official standard issue ACH helmets

The Batlskin Cobra Head System components—Front Mount, Mandible Guard, side rails, and Visor—have been designed to fit the Revision Cobra P2 (composite) helmet.

Currently, Batlskin Viper and Cobra Head System components are available for all four helmet sizes: S, M, L, and XL. 

The Caiman Head System components—Mandible Guard, Wilcox® Shroud, Visor, rails, armor appliques—have been designed to work with Revision’s Caiman Hybrid Helmet System, Caiman Ballistic Helmet System, and Caiman Bump Helmet System. 

What is the difference between a Viper, Cobra, and Caiman head system?

Revision’s three Batlskin helmet families—Viper, Cobra, and Caiman—are all robust, leading, and versatile head protection systems. The difference between the three families comes down, largely, to shell shape, system architecture and design, and the associated head system components tailored to the make of each. Viper is based on the U.S. Army ACH-style helmet. Cobra, on the other hand, was designed with European markets and customers in mind, emphasizing more crown protection in line with European standards, particularly EN 397. And, the Caiman System is a scalable, lightweight solution—developed for and in collaboration with Special Operations Forces (SOF) users—designed to integrate with up-armor ballistic appliques. To find out more, and to examine the nuances within and between these head systems, view the sales sheets and product summaries for each. Viper Head System information can be found here; Cobra Head System information can be found here; and Caiman Head System information can be found here.


head systems protection

Do I lose protection with a lighter helmet?

Protection is always foremost in our minds when we engineer our head protection systems. However, we are very aware that head protection is not an entirely linear proposition: helmets must be very strong but they also need to be streamlined for fast-moving operations. Revision works with advanced materials and cutting-edge manufacturing processes to optimize the balance between weight and superior ballistic protection. Revision head systems components—including the Mandible Guard, helmet shell, and Visor—provide a weight versus protection ratio that is commensurate with U.S. Army ballistic requirements and the operational realities of today's battlefield.

Does the Batlskin Head Protection System protect against blunt force, blast, and ballistic threats?

Yes. To help reduce brain injuries, Batlskin Viper helmet systems, Batlskin Cobra helmet systems, and the Batlskin Caiman Ballistic Helmet System have been designed to mitigate ballistic threats, but also to protect against blast waves, deflecting and absorbing energy. The High-threat Viper Mandible Guard, the Cobra Mandible Guard, and the Caiman Ballistic Mandible Guard also offer blunt force and blast fragmentation protection for the lower face and jaw. Injury models include both ballistic and non-ballistic injuries, so the Batlskin Head Protection Systems provide additional protection against blunt impact and blast force to the face and jaw, such as those cause by collision with vehicle interiors and weapons. The Caiman Hybrid Helmet System provides ballistic protection with the addition of the Caiman Armor Applique. Both the Caiman Hybrid Helmet System and the Caiman Bump Helmet System meet or exceed advanced combat helmet (ACH) standards for impact protection. 


head systems miscellaneous

What is the difference between the Caiman Bump Helmet and the Caiman Hybrid Helmet?

The Caiman Bump Helmet has a reinforced polymer shell whereas the Caiman Hybrid Helmet has a carbon fiber shell. As a result, the Caiman Bump Helmet is slightly lighter in weight, whereas the Caiman Hybrid Helmet provides a bit more protection against blunt force impacts—though they both meet or exceed advanced combat helmet (ACH) standards for impact protection. 

How does the Ballistic Applique attach to the Caiman Hybrid Helmet?

The two-piece Ballistic Applique attaches to the Caiman Hybrid Helmet with Velcro hook and loop.

When wearing the Batlskin Head Protection System, will the visor fog?

The Ballistic Visor has Revision’s industry leading OcuMax Plus anti-fog coating on the inside of the lens. In severe environments, the Visor can be articulated to the ‘vent’ position to further reduce fogging. In an emergency, the Ballistic Visor can also be quickly removed. For more information, watch this video.

How breathable are Revision head protection systems?

Unlike a gas mask, the bottom of the Mandible Guard has an opening to ensure ventilation and proper air circulation. In severe environments, the Visor can be articulated to the ‘vent’ or ‘up’ positions to increase ventilation. The Batlskin Head Protection Systems were designed with thermal mitigation in mind. Each component of the system is modular and can be utilized in depending on environmental conditions and situational threat level. For example, for extra ventilation, you can wear the Visor without the Mandible Guard.

When wearing the Batlskin Head Protection System, how easily can you communicate with others; are face-to-face conversations clear? Can I use communications equipment?

The Batlskin Head Protection System has been specifically designed for use with over-the-ear communication headsets. The Mandible Guard provides sufficient clearance for communication headsets, boom microphones as well as the headset earpiece. The Mandible Guard can easily be tilted downwards by varying degrees allowing for improved sight capabilities, eating, and drinking.

How wide is the field-of-view when wearing the Batlskin Head Protection System?

The optically correct ballistic Visor provides the same field-of-view as the ACH helmet and is manufactured to ensure distortion-free vision across the whole panoramic surface of the lens. When the Mandible Guard is in use, the field-of-view is comparable to that of ballistic goggles. If additional field-of-view is required, the Mandible Guard can be easily removed.

How do you use weapons with the Batlskin Head Protection System? Can you achieve a proper cheek weld while sighting weapons?

The Batlskin Head Protection System is intended to be used with current weapon optics. Most standard red dot, holographic sights and scopes are capable of being used with this system. For use during limited visibility operations, standard IR lasers can be utilized without a cheek-to-stock weld. As a contingency, the ballistic mandible is easily removed for use with traditional iron sights. Watch the video.


power compatibility

How do I update the SharePack's firmware?

The SharePack supports in-field software updates through a connection to a PC via USB. A host interface application designed and developed to be an intuitive and self-explanatory product is used to execute the SharePack field firmware updates. For instructions, please refer to your SharePack user guide.

What if Revision doesn't have the specific cable I need?

Revision can explore sourcing additional connectors. Please email with your request.

How many SharePacks can I string together and what is the maximum power emission?

A network of SharePacks can support up to 8 in a configuration, whether in star topology or as a daisy-chained hub. In a star topology (parallel) you could theoretically emit 800W (8*2*50 = 800W) of power. In a daisy-chain topology (series) you are limited to emitting 50W on your output port; however, the duration of your power emission is multiplied eight-fold.

What kind of charger should I use to charge the SoloPack and SharePack?

Any SMBus charger should be used to charge the SoloPack and SharePack rapidly and most efficiently. Some examples include Desktop Evaluation Charger (6130-01-542-5108) and Soldier Charger (6130-01-545-1983). The SharePack can, however, be recharged from any energy source. A full comprehensive list can be found in the respective user guides.

How do I set up my battery to work with my equipment?

Please refer to the accompanying instruction manual for step-by-step instructions on how to connect your equipment to your SoloPack and SharePack. Instruction manuals can also be accessed by scanning the code on the back of your battery using a smartphone or mobile device.

What equipment is compatible with my battery?

Nerv Centr products have been designed to work with a wide range of currently fielded equipment. For additional information, please email Associated accessories required to power your equipment can be found here.


power safety

If the battery is not being used, how frequently do I have to charge it?

If the SharePack will not be used for a week or longer, it must be fully charged and put into shutdown mode. Otherwise, the SharePack will deteriorate and last only a few months as opposed to a few years. Failing to charge and shut down will leave the SharePack consuming a small but continuous amount of current which can drain cells to a point where they cannot recover. If the SoloPack is not being used, simply charge the battery to 50% and leave in an ambient environment. It is recommended to perform maintenance recharges back to 50% at regular intervals, two or three times a year, to maintain the battery in optimal condition. Otherwise, its shelf life is approximately 3 years.


The batteries should be stored at 50% state-of-charge, placed into shutdown mode (no equipment or cables connected), and at an ambient temperature of 25°C. The shelf life under these conditions is 3 years. Please note that the SharePack will need occasional recharging back up to 50%.

Can I store a depleted battery pack for a long period of time without causing damage?

With smart batteries like the Nerv Centr SharePack and SoloPack, if left unattended for a month after complete depletion, the lithium-ion cells may be permanently damaged, rendering them unsalvageable.

How deeply can I discharge the SharePack without failure?

The battery can be depleted down to zero percent. As a safety mechanism, the software will display an 'Apply Charger' message when getting critically low, informing the user to recharge the SharePack. If the battery is not charged after this indicator appears, the software will internally shut-down the device and it will only awaken once connected to a charger. This automatic internal shut-down protects the lithium-ion cells.

What happens if I use my battery outside of the operating temperature range?

The SoloPack and SharePack will disable charging and discharging through the battery cell stack when the internal temperature reaches 70°C ± 5°C. It will resume normal operation when the internal temperature reaches 50°C ± 5°C. Charging and discharging through the battery cell stack will be permanently disabled should the internal temperature exceed 93°C ± 5°C.

What happens if a SoloPack or SharePack is hit by a round or shrapnel?

Revision’s battery systems offer the same level of safety as other man worn batteries currently in use by the U.S. Military. The SoloPack and SharePack will behave in a similar manner to most standard military batteries such as the BB-2590 or LI-145; they may heat up or, in extreme situations, could conceivably catch fire if hit by a round or shrapnel. Revision continues to investigate operationally safe battery systems.

Is there a potential to damage my equipment if I don't set the voltage correctly?

It is important that the ports are set in accordance with the voltage required by the piece of equipment being powered. Otherwise, there is a possibility that the equipment could be damaged. Please pay special attention when setting the voltage.

How do I dispose of the battery?

Similar to one-time use batteries and cell phone batteries, the SoloPack and SharePack can be disposed of in commonly used battery disposal boxes. Please contact your local battery recycling program to determine your nearest disposal location.

Are there any regulations for shipping these batteries?

Yes, please call your local shipping station to determine and verify any restrictions or regulations related to shipping these batteries. The SharePack and SoloPack have passed the UN/DOT 38.3 Certification but regulations for shipping and transporting lithium-ion products have changed recently and vary by size and power output. For more information, here are several useful references: IATA (International Air Transport Association)FedExUPSTNTDHL. Watt-hour (capacity) information is listed on the front of your battery.

Can I take these batteries on a commercial airline?

It is incumbent upon travelers to verify with airlines whether restrictions have changed prior to boarding, and to seek approval for carrying lithium-ion batteries in their carry-on luggage. Due to frequent changes in lithium-ion battery regulations, please contact your airline for information. Restrictions and regulations apply depending on the airline, and vary based on the power output of the device. Watt-hour (capacity) information is listed on the front of your SoloPack or SharePack. Both the SoloPack and SharePack have passed the UN/DOT 38.3 Safety Certification.

Will the SoloPack and SharePack function underwater?

The SoloPack and SharePack are designed to meet the MIL-STD-810G Immersion - Method 512.6 Procedure I, which is meant for equipment that might get inadvertently immersed (i.e. accidentally dropped in a stream) but are not currently designed to operate underwater. Should a sealed power solution be of interest, please email Please note that underwater operation requires a different class of connectors (not NettWarrior compatible) and a significantly bulkier design to protect from water damage.


power miscellaneous

What is the energy density of the SoloPack and SharePack?

The SoloPack's energy density is 175 Wh/Kg, containing as much power as 64 AA NiCd batteries and offering 4.25 times the energy density. The SharePack's energy density is 135 Wh/Kg, containing as much power as 100 AA NiCd batteries and offering 2.75 times the energy density.

I have lost my instruction manual. Can I access instructions online?

The instruction manual for the SoloPack and SharePack can be accessed by scanning the code on the back of the battery using your smartphone device.

How long will my battery last?

SharePack is rated for 152Wh and SoloPack for 96Wh. The amount of runtime depends largely on what and how equipment will be used. When fully charged, if powering equipment that draws one watt continuously, you can expect to get 150 hours (6.6 days) of runtime from SharePack, and 100 hour (4.4 days) with SoloPack. Most handheld radios will require 2-3 watts when not transmitting. This means you can expect approximately 2-3 days of runtime (this is reduced when transmitting). Larger radios will require much more power (10-20W) which reduces runtime to a couple of hours. The best indication of runtime is displayed on the SoloPack's state-of-charge display or the SharePack's main screen and this will be your best indication of the duration of battery life.

What is the operating temperature range of Nerv Centr products?

The SoloPack and SharePack are designed to operate in temperatures of -32°C to +55°C.

How will I know if my battery is dead?

A 'Servicing Required' error message will appear, indicating that the SharePack should be returned to the manufacturer for servicing.

What happens if the USB cable is disconnected while updating the SharePack's firmware?

It is crucial that the user responsible for updating the device ensures that it is properly connected to the PC and that once updating commences, the cable does not become disconnected. Disconnecting a cable during an update may render the SharePack unusable, requiring the battery to be returned to Revision for servicing.

How many SharePacks can I update at once?

There is no limit to the number of SharePacks that can be updated at the same time—as many as you have USB ports to support. The software will recognize these connected devices and update them one after the other.

How often should I recharge my SoloPack and SharePack?

The batteries should be recharged after each use to prolong life. Unlike the internal chemistry of other battery types, lithium-ion batteries will never 'crystallize' or develop a 'memory'. They can be recharged at any state-of-charge and will only show signs of lost capacity after several thousand cycles.


comms systems compatibility

Is the ComCentr2 system compatible with legacy radio systems?

The Revision ComCentr2 has built in compatibility with legacy systems. However, while operating with legacy systems, the headset may inherit problems the legacy system may have. For example, cross talk between radios due to shared grounds on six pin connections, band limited audio outputs etc. Only when connected digitally would the user achieve the top features. 

Is the ComCentr2 system interoperable with next generation, future radio systems, and mobility platform ICS?

The ComCentr2 has been designed as a next generation digital headset and is fully compatible with USB2 audio as standard, allowing integration of modern and future systems. When connected digitally, additional features will be activated. These include 120dB of channel separation, RF immunity passed 200V/m, power savings, and overall better communications signal. Advanced spatial and restorative techniques allow the user up to 10 communication signals, each having increased intelligibility. Additionally, the new digital Active Noise Reduction (ANR) delivers high level of protection against low frequency noise, increasing clarity, reducing fatigue and long term noise-induced hearing loss.  

Can the headset be used with my push-to-talk (PTT) device?

Yes, the ComCentr2 Headset is compatible with legacy PTTs. Contact Customer Service at for more information. 

The communications equipment I use is not compatible with the dongles currently offered. Is there a solution?

Revision has the ability to design custom dongles to function with various comms equipment. For more information, please contact Customer Service at

Yes, the rail mounted ComCentr2 Headset can be used with commonly used helmet rails, including Revision’s Interlocking Long Rails, Standalone Rails, and Mini Rails.


comms systems miscellaneous

How is the ComCentr2 Headset powered?

The headset houses a single AA battery in the right ear cup. The single battery can power the headset for up to 3 or 4 days. When connected to device, the headset will parasitically draw a low amount of power.

With internal electronics, tactical headsets sometimes have issues with EMI, bleed-over/crosstalk, and many points of failure. How does the ComCentr2 mitigate these issues?

Unlike older analogue-only products, the Revision ComCentr2 system design is focused around a digital core contained inside a single chipset. This reduces the number of components, potential points of failure and high impedance analogue tracks which allow EMI to enter the audio paths. Additionally, the digital core allows signal processing to take place in the software outside of the EMI. This means only the inputs and outputs have to be protected. Transducers are differentially wired to provide common mode rejection and are kept at high absolute level. Products using these techniques in the past have easily passed 461F RS103 at 50V/m without fitted protective screening cans. The ComCentr2 goes a step further and adds screening cans to all internal electrons to target 100-200V/m protection. 

Is it possible to change the ear cushions and headband cover for hygienic reasons?

Yes. The ear cushions and headband cover can be easily switched out for new ones. Revision offers a Hygiene Kit that includes replacement ear cushions.

Where are the power and volume control buttons located?

The power and volume buttons are located on both the left ear cup of the headset. That way, the headset can be worn by itself, without the Human Interface Device (HID), if comms equipment is not needed. Volume can also be controlled via the HID. 

Are there different sizes of headset headbands?

The headband is designed to be one-size-fits-all and can be easily adjustable to accommodate all head sizes.

Is the boom mic ambidextrous?

Yes, the boom mic is ambidextrous and can be easily moved to the preferred side.
