| Re: Optima ExtendAir Duration Experiences? Apparently you guys are getting a MASSIVE DEAL!!! Out here in the WILDS of BEIRUT LEBANON we pay a wonderful $65 PER EAC!!! We change after three 1 hour dives. Usually covers about 2 days and never more than a week. Dives hit about 40m and are multilevel with minimal deco commitment. I know that deep dives increase ppCO2 and that the EAC would burn faster so I don't double up on deep deep dives. I'm sure I could get more out of the cartridge but in order to preserve the reputation of rebreathers and of the club with which I dive... I prefer to keep a spotless record. |
