Recreational Trimix Course

[Inspirationdiver]

I think Chuck has a good point here. There is a significant narcosis level in the 130ft range. A lot of you out there who are doing deeper dives on air instead of trimix have become comfortable in the degree of narcosis that you experience. The thing you are forgetting is what it was like to go to 130ft before you had ever made any of those deeper dives. For those who don't have any intentions to make dives past 130, it would be nice to have a clear head while diving within those limits. I have been diving trimix exclusively this summer on all my dives up to depths of 270 ft. This past weekend I did a couple dives on air with my rebreather in Isle Royale to depths of 140 ft. I definately felt the effects of narcosis. I think this class has its merits, but it won't appeal to everyone. It really depends on what your long term goals are in diving.
