Why is the max depth of Helitrox 150ft, while air goes to 180ft???????

Depends on what mixes you're actually able to get with the card.

No problem. When we used to buy bulk oxygen and helium from the local gas supplier they wouldn't take my credit card so I just paid by personal check.

I think it has more to do with the idea that the helitrox is an alternative to deco procedures. Helitrox is trimix with training wheels, only 1 deco bottle and up to 32% He. It's not 200ft because that's the territory of the normoxic trimix course.

Extended range is deeper because it teaches the diver to handle two deco bottles, like in the trimix course.

You might want to read those standards again. Just sayin'. . .

Care toi enlighten me?
Mind you I am not an instructor of these, but I have been reading the standards and thought I kind of got it.
