Recreationall TRIMIX

[FreediveWI]

The reason that the MOD is where it's at is because this mix is still mostly a nitrox mix- 02 limits depth and not the helium.

The idea of the course is to make exisiting dive profiles safer. If you want to go deeper you need the full blown course. Don't waste time with deep air courses that are quickly going the way of the dinosaur.

Also, deco times are not longer with trimix over air. The limiting factor is how much 02 you have in the mix. The more 02 the less deco time, but you also limit your depth at the same time.

On longer dives to the Wisconsin (max depth around 132') we find that we can actually deco out a few minutes faster using a 28/30 trimix rather than just nitrox, and much faster than air. OF course, these are all dives involving bottom times of 45 minutes or more. If you just bouncing down for a 15 minute dive you get out 1 minute faster on the nitrox mix. Super long deco times on trimix are just another one of the misconceptions about the gas that are out there.
