The cutting-edge
The RedBare CCR evolved from the popular RedHead CCR. Building upon the CE tested and field proven performance of PO2 tracking and CO2 monitoring, we have upgraded the configuration to offer considerable enhancements to both work of breathing and travel convenience.

RedBare CCR retains the reliable concept of full life support system monitoring - everything that you need to know about is condensed into a simple Head Up Display (HUD).

When we say that the RedBare is built for exploration we really do mean it - the RedBare CCR is built from the ground up to meet the demand of the most challenging environments. That means everything from operating reliably at the extremes of exploration to the world of the sport diver, where every day and weekend's diving has to be fitted into busy domestic schedules. The same qualities that keep the redBare diving in caves and wrecks will make sure you don't miss your favourite bucket list dives.

"If you are pushing your own limits and the limits of diving you have to have something that will stay the distance and depth with you. The RedBare from VMS does that and so much more."
Paul Vincent Toomer
DiveRAID International
"Expedition diving demands kit that is mission critical and that's exactly what you get with the Redbare rebreather. No other rebreather features such robust safety and backup systems."
The CCR REDefined
The VMS RedBare closed circuit rebreather combines excellent CE-proven performance across all tests with a simple user interface and new robust, modular assembly.

Evolving from the Sentinel Expedition, the RedBare CCR offers multiple upgrades on breathing performance, weight, reliability, field servicing, travel flexibility, PO2 tracking, configuration and software.

These upgrades take the RedBare CCR to a class leading level of performance with true integrated resource life support capability. The RedHead has the clearest early warning system for ALL resources available on an expedition-grade CCR.

Subjecting each component to intense scrutiny has resulted in a step forward in diving enjoyment, performance and safety.

PO2 Tracking...
Knowing your PO2 is the golden rule of technical diving! The flipside of this is keeping that PO2 steady throughout the dive - fluctuations and wobbles don't help.

PO2 is monitored by the RedBare CCR via three cells, with custom sampling rates to deliver precise control and adjustment. Breath a bit quicker, descend or ascend - the RedBare CCR will have your PO2 nailed back in place with varying injection rates to suit ascending, descending or holding stops. The most precise adjustment is only 50 milliseconds long - just right for PO2 control at 100 metres.
Redundancy & Modularity...
All technical diving requires a backup system and the RedBare CCR offers a backup process for virtually any scenario.

It includes manual bypasses, component control and a complete Independent Secondary that uses a 100% separate information route to track PO2 and decompression obligations live. That's a second trimix CCR computer working for you, included as standard!

The RedHead features robust plug and play cable connectors to enable rapid component swapping for diagnosis and trouble shooting.

Damage to individual components in remote locations is no longer trip or dive ending when combined the with 'Platinum triage kit' concept for team diving. The kit includes spare handsets and other critical modules to be taken to remote locations ready for instant use with minimum tools.
Life Support
Early Warning Before the Incident Pit
All rebreather divers agree that they need enough breathable gas, a working scrubber and battery power that will last the dive.

Each dive is spent monitoring these resources by contents gauge, O2 cells and maybe checking for headaches to detect CO2 (the ability of the human body to detect CO2 before problem levels is not reliable).

The RedBare CCR takes the legwork out of these checks by directly monitoring PO2, CO2, HP on diluent and O2, plus sofnalime temperature and battery levels, leaving you to focus on enjoying your dive.

When levels are normal, the RedBare CCR displays a green light on the HUD. Problems display as either a 'manageable error' flashing blue green, or a 'Bailout' flashing red, backed up by a patented buzzer. Further information to prompt fault finding and problem resolution is found on the handset. It's a very simple system that works.

The RedBare CCR is able to relate remaining CO2 'scrubbing' time to divers metabolic activity, giving accuracy of scrubber use that is not available on any other CCR. The harder you work, the more CO2 you will produce and the shorter your sofnalime will last. The RedBare CCR takes away the guesswork.
Electronics Vault
At the heart of the RedBare CCR lies the electronics vault. Machined to fine tolerances from Delrin, the electronic brain is formed from plug and play boards with moisture repellent coating, encased in a robust pod.

All connections to this pod are internally potted to limit water ingress and it is removable for electronics protection during travel. One classic weakness of a CCR is the depth sensor leaking - this is now potted into its own mount to reduce water entry from O-ring or sensor failure.
Stable Gaseous
CO2 monitoring...
The RedBare CCR rebreather features the world's first and only gaseous quadruple carbon dioxide (CO2) filter monitoring system that provides unparalleled level of confidence and safety.

Whilst other manufacturers offer CO2 monitoring as an expensive optional extra, the RedBare CCR is fitted with full CO2 monitoring as standard - we're the only rebreather manufacturer to include this all-important safety feature at no additional cost.

The RedBare rebreather's CO2 monitoring system uses Infrared technology to detect CO2 levels within the rebreather. It's primary functions are to to ensure active obsorbent has been fitted, to ensure that the obsorbent sealing systems are operative and to warn of reduced obsorbent efficiency resulting in elevated CO2 levels, giving the diver time to respond. To ensure stable and accurate readings, the CO2 sensor is positioned within the warm and dry inhale side of the unit - effectively measuring your next breath before you've taken it.

The CO2 sensor features a lifespan of several years (dependent on use) and needs only to be periodically calibrated in ambient air. An integral filter system is user changeable and spare filters are supplied.
Scrubber Duration...
Whether you're diving for fun or pushing the very limits of dive exploration, the RedBare CCR boasts a cutting edge scrubber design that delivers exploration grade performance.

Based around a relatively small 2.2 kg axial scrubber design, the RedBare rebreather's scrubber offers the longest CE-test duration on the market - a massive 4 hours under rigorous test conditions. What's more, our scrubber is rated in 4 degrees centigrade water - not tropical conditions!

The secret to this market-leading performance is an efficient design that incorporates an air gap around the scrubber that acts like a Thermos® flask, effectively insulating the scrubber from the environment around it. This insulation ensures that the RedBare CCR doesn't suffer from the massive endurance reduction with depth that plagues other rebreathers on the market and provides a very dry environment for the oxygen cells, significantly improving sensor accuracy and lifespan.

The RedBare rebreather's scrubber is quite literally 'engineered for exploration'...
Unrivalled work
of breathing...
The RedBare CCR excels with one of the lowest work of breathing of any rebreather on the market - just 0.48 Joules per litre at 100 metres on 10/80 trimix.

Work of breathing (WOB) is an important consideration when choosing which rebreather is right for you - poor work of breathing can lead to increased CO2 levels and a generally unpleasant diving experience.

With the RedBare CCR, exceptionally low work of breathing is achieved through a fusion of intelligent design and use of only the highest quality components. The Sentinel RedHead's unique single back-mounted inhale counterlung is positioned centrally between the canister and chest to aid work of breathing. Gas flow is further enhanced thanks to a superior canister design and high quality large bore breathing hoses.

Completing the ensemble, the RedBare CCR benefits from ultra-flexible, large bore silicon mushroom valves to aid gas flow, reduce CO2 and deliver an enjoyable diving experience.

Buying your new
If all the safety features and benefits of RED Series diving have convinced you that a RedBare CCR is for you, the next step is to find an instructor.

Your choice of instructor is as important as your choice of rebreather. You need an instructor who teaches like you learn, who has a deep understanding of the RedBare CCR and will continue to support you after you qualify - even if that's just answering all those little questions that we all have once you start your journey down the CCR path.

For divers wishing to purchase their first VMS unit, new RedBare rebreathers can only be purchased through a network of VMS-approved instructors representing all the major training agencies - VMS only sells direct to existing Sentinel or RED Series-qualified divers.

We've made it simple to find an instructor - you can view the complete list on our website. We've only listed instructors who own and are actively diving their units, with a special red shading for those who have completed the orientation to the extras on the RedHead.
