    More (possibly conflicting) information is a recipe for disaster imo. With cell issues it's the human factors cock up thats the problem.

    With three cells it's abundantly clear if you have an issue. Even the much talked about double current limited scenario. It's also possible to diagnose the issue with three cells.

    I could run my unit with 4 cells but it wouldn't provide any benefit over 3. Much like with 5.
    Me, as a numpty novice, could clearly see that the weak cell (moved to number one position) was colluding with the second cell and that the other three which had all behaved that week were in agreement.

    More importantly though is that you’re happy to dive without redundant cells and electronics. I’m not, so I’m very happy to have three cells on the Petrel controller and two completely separate cells with independent wiring on the backup Nerd.

    It’s a tempstick.

    Actually, it’s way way more sophisticated than that. The scrubbers have four dual temperature probes in the sorb and one below the can which are inductively connected to the receiver. This, in Conjunction with the controller work out the reaction front and estimate the time remaining taking into account the diver's weight and gender. Of course this will change when under work or rest, but this is easily understood with the estimated remaining time on display.

    TBH I was really impressed with this tech. Saves a fortune in scrubber and would be invaluable in overhead diving.

    I run 4 cells. 3 for the Inspo, and the 4th as a spare. Inspo is 123, Nerd is 124. So if one cell craps out, at least I know my spare is working when I drop to 3.
    There has been at least one fatality of an experienced diver using out of date cells where one deviated and he believed the other 2. Sadly it was the 2 that were faulty together.
    What's da solution kidz? What should you do with faulty cell readings?
    I have nothing to do with BSAC any more apart from being a muggle member. So anything I write on here is likely to be complete bollocks. Hooray!

Scrubber usage is amazingly frugal, 1.3kg a fill plus the only accurate scrubber monitoring system that correctly predicts the remaining time. A redundant second scrubber. It is dived with flat trim and has really simple attachment system for the suit inflate and batteries.

    The choice was a no-brainer over the other Inspiration-style units. Owning and diving a Revo has just reinforced my choice.
    Lol so you spent the week on mod 1 learning how to give the manufacturers sales spiel :-P

    If you moved the cell, you knew it was faulty. Why would you dive with a cell that you knew was faulty?

    We all know the answer to that. You can't get new cells at the moment and a Revo has 5 cells to choose from.
