Introducing the new
Sentinel RedHead CCR
You might not dive ancient wrecks or explore deep virgin caves for a living... but your rebreather should be built like you do.

When we say that the Sentinel RedHead is 'engineered for exploration', we really do mean it - the Sentinel RedHead is built from the ground up to meet the demands of the most challenging environments.

The Sentinel RedHead combines class-leading performance with a simple user interface combined with a new robust, modular assembly that makes the unit both easier to maintain and travel friendly. Certified to the most stringent 2013 CE test standard, the new RedHead marks the development of a new generation in exploration-grade closed circuit rebreather technology.

An evolution of the Sentinel Expedition, the new Sentinel RedHead offers multiple upgrades on breathing performance, weight, reliability, field servicing, travel flexibility, PO2 tracking, configuration and software.

The best just got better...
Experience rock-solid oxygen setpoint control delivering just +/- 0.02 Bar variation at 100 metres
Breathe easy with the lowest work of breathing of any rebreather on the market
Robust plug and play components can be switched out in the field - no specialist tools required
With trimix software enabled as standard, the RedHead is ready for trimix from day one
We don't charge extra for a carbon dioxide sensor - it's fitted as standard on the RedHead
The new RedHead features a new travel-friendly modular design with significant weight savings
No faffing with batteries - both the oxygen sensor module and primary pod are now fully rechargeable
Quick and convenient wireless downloading of dive log data direct to your personal computer
Try dive the
Sentinel RedHead...
To truly appreciate just how good the Sentinel RedHead is, we strongly believe that you need to take one for a dive.

Working with some of the very best Sentinel instructors in the UK and Europe, we now offer you the opportunity to 'try dive' the Sentinel RedHead for yourself. Over the coming months, our team of Sentinel RedHead instructors will be taking the Sentinel RedHead on the road to give divers like yourself the opportunity to experience the RedHead for yourself.

You'll get the opportunity to discover how the RedHead works and how all the technology fits together. Of course what really matters is how well it dives and you'll get to do this too - try dives are open to any diver with open water training. Prior experience is not required.
