Out with the old, in with the new!

Out with the old and in with the new. My AP14 oxygen cells have given me a solid 18 months (well nearly all of them - see link in comment), which is exactly where I draw the line. Time for a fresh set, and these should see me comfortably through to mid 2027. One of my cells didn't make it to 18 months and died on a 90 metre dive! Wtach my video of that here - https://champ.ly/LPkv1Uis #Deepwreckdiver #WreckDiving #technicaldiving #closedcircuitrebreather #apdiving
