Scuba Diving around & under the Saltfree Pontoon

April 20, 2016

Saltfree Pontoon

As a reminder for scuba divers – please could you avoid the area around & underneath the Saltfree Divers pontoon when their A flag is flying and they are freediving.

In particular we also request that divers do not use the freedive mooring lines for decompression stops.

If the freedivers had to release their counterweight system in an emergency, there is the risk of being caught by a 60kg weight.

The upcoming freedive meets are as follows:

• 30 April
• 1 May
• 21/22 May
• 11/12 June
• 9/10 July
• 30/31 July
• 6/7 August
• 27/28 August
• 10/11 September
• 24/25 September
• 8/9 October

We’d also like to remind any divers using re-breathers that you must also use a Surface Marker Buoy (SMB) throughout your dive. (However please note that yellows SMBs should only be used in emergencies.)

Thanks for your understanding.

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.
