pakman:wait til you see your gas bill after the trimix class... you'll be selling your brand new HID for a couple weeks of helium fills... But why fight the urge to sign up for trimix? amazing how helium clears your head even at the 30-50m range.
BTW, what kind of gas planning did you guys do for this penetration? simple thirds, gas matching, ?
bobby made a strict dive plan and we made sure we had more than plenty of gas to spare at the bottom for 25 mins. simple thirds after 25 mins we ascended to 70ft before gas switching for our deco obligations. i still had about 120 bar on my twins at the end of the dive
