On open circuit 50m is about my change over from air to 'mix (all viz, temperature, anticipated stress levels dependent) - old habits from 20 years ago when Helium was hard to come by and DrX was the only software that could cut Trimix tables. Closed circuit I usually add He if I go deeper than 35-40m .... but I think I may have hijacked the thread, sorry.Chopping Broccoli wrote:50 meters on air? It might be time to consider adding some helium in your breathing gas.

I swapped out the Caspian on my BC for an Atlantic Salt last weekend ... Atlantic Salt in a pouch is less cluttered than the Caspian was (at the expense of having a folder rather than a fixed blade). Caspian will now live on the deck of my kayak.
