    Diluent flush and current limited cells

    There's a few things I do to check cell health, Dil Flush can be one of them. Here's my list: - check the cell's output with the previous calibration values. I like to do this in air with the lid off and expect to see 0.21 0.21 0.21 - check the end cal-values with the previous end-cal-values...

    CCR Storage

    I stand mine on the back of the shipping crate propped-up by an old sofnolime keg. In the garage during the spring-autumn and in the house on the floor during winter. I prefer to leave the unit assembled but not sealed. Mostly so I don't misplace any of it. Matt.

    Storing part-used scrubbers

    Completely agree that you cannot tell the difference in WOB that can easily be detected by a machine. Complete voodoo, just like mixing gas ;-) Also (and this also depends on the scrubber design) I have seen a cartridge so over-full on the inspo that the side of the canister bulges out and...

    Storing part-used scrubbers

    Interesting that the hard pack didn't increase WOB. Personally I can't detect WOB differences in my Inspo and I've tried packing all ways. The loose method (per the video) is too loose for me; I'm a medium packer. And I typically do use the temp-stick for duration estimation (especially in...

    Storing part-used scrubbers

    Interesting info thanks. Did you get 10% more material in with the hard-pack/+20min duration? Do you have any theories on clumping; does it matter/why caused, etc.? Cheers Matt.

    Solid State sensors

    I like your passion, but I haven't changed my mind as yet. I wait to be surprised, though. Can't see the M28 being that popular compared to the current set-up which is working fine and has more options for monitoring. We can agree to disagree. Matt.

    Solid State sensors

    My view is entirely based on what I have seen. Poseidon is a tier-2/3 rebreather (my view), with the likes of APD, JJ, Meg and rEvo being the bigger players. If you want to make a disruption then you need to have these players on-board, from the off, so they can be part of the disruption, make...

    Solid State sensors

    These cells have the potential to be distuptive to rebreather manufacture. But I fear they won't achieve this due to the narrow mindedness of the way they have been developed. Does anyone know who now owns the rights to the patent - I believe it was developed by Arne Sieber et al at SeaBear...

    Sofnolime in Indonesia

    I dived both locations with 2Fish, and HP O2 (they have a booster) and lime (797) no issue. I took my own Inspo cylinders. Matt.

    Rebreather market data

    Assuming 25% of the 50M is APD rather than AP, and revenue split 60/40 sales/service then that would be 5M is unit-sales. Average per unit of 5k would be 1,000 units sold. Assuming 75% of the 50M is APD rather than AP, and revenue split 60/40 sales/service then that would be 22M in unit-sales...

    Rebreather market data

    Understood that total-sales and in-use are different, but do you think APD are close to 10k sales? Nearly 20 years in the market, and not gone bust? Matt.

    Indicating lime

    With 797 I am happy to go to "last 2 blocks". With others I treat the last 3 as exhausted (pure guess work though). Matt.

    Krzysztof Starnawski completes 230 meter deep cave dive on CCR

    Nice. I liked how the Suunto Eon imploded just shy of the bottom - and of course the bump! Gotta be nuts! Matt.

    I was never convinced that those 2 minute stops were accounted for in the initial TTS either.

    GF settings

    If you're only doing 5m per min then you could set the ascent rate in your program to 5m per min? I took a quick look at 40 mins 80m, 15/85: 10m/min first stop 48m, last stop 81 mins, total-time 210 mins. 5m/min first stop 54m, last stop 86 mins, total-time 225 mins. Both ends of the dive...

    90/95 for air diving. 50/70 for gas diving. May move to 70/75 for the gas diving. Matt.
