Sentinel LSS Level 3 Tear-down This tear-down is based on my own knowledge/experience/ownership of the Sentinel LSS Level 3; LSS standing for "Life Support System". It's intended as a high level overview of the system based on my 156 hours of diving the unit, please refer to the units...

Dust can be an issue on the Sentinel, has wire mesh on the scrubber cartridge rather than a scrim like the Inspo. If you load the scrubber (gets ejected) then re-open you see dust in base of can. Have had this lime dust effect the OPV at the base of the scrubber which lead to the unit...

I've dived two types of unit, one key difference was where O2 was injected: 1) Inspo (JJ as well?) injects on the inhale side close to the O2 cells (not directly on to them) 2) Sentinel injects O2 on exhale side, cells on inhale side Which is better? I tended to use less O2 on an Inspo...

The classic had an on/off switch so that no battery power was consumed when off. The Vision doesn't have this as handset has to monitor the buttons for switch on & other stuff. So it consumes power when notionally off. The power consumption is enough for me to take the batteries out if not...

Following on from Clare's thread on "Bailout - quantity and access", I wondered how many divers have had to bail out for real? I'm not talking about practice bailouts..... 3 times in my case.... Flooded scrubber canister (Inspo) Loop flood thru OPV valve (Sentinel) WOB problems...

Maybe the existing INSPIRATION forum should be renamed to Inspiration/Evolution to reflect APD product range i.e. Inspiration Classic & Vision Evolution Evolution+ All variations of the same basic RB. Also capitalized looks better than all upper-case.... Otherwise, looking good...

Unit dived: Inspiration Vision Problem - ADV leaking hypoxic diluent into loop On a dive, all seemed OK, until I reached the shallower stops. We'd been diving a wreck @ 65m with a bottom time of 36 min, so looking at around 45' deco at 6m, after deeper stops. At 6m I noticed that the set...
