I am still a little new to diving. I understand why people get into tech diving. I would love to go wreck diving and have the skill to go deep if I needed to. What I can't figure out is why caves and deep air.
What do you see in caves?
Why do your deep dives on air? Why not use a mix gas?
I would really like to know what you get out of it and why you do it. I learned to dive to see the reefs and the life on them. I also like the thought of wrecks especially when they are historical or might contain gold.
So why do you do what you do?
I got into diving, and started in tech because I wanted to dive wrecks, and in particular historic, wooden sailing vessels. I'm particularly interested in some of the wrecks in the Great Lakes (which I haven't dove yet). Why not tri-mix? simply because I haven't progressed that far in my training and experience yet. I want to get in at least a solid year of tech diving on air, probably more, before I add the complexity and additional risk of He.
Caves? When I started diving I have absolutely no interest in diving caves, thought it was way too dangerous just to go look at a bunch of wet rocks, and felt uncomfortable about the overhead environment. one of my best buds was a big cave diver in the late 70's - 80's and had regaled me with all sorts of lurid tales of body recoveries.
then I made the mistake of diving some caverns, in particular the cavern at Morrison Spring. After a nasty descent through mung laden water with minimal visibility....suddenly a peaceful, beautiful room with rock formations like a high gothic cathedral....and water so clear it was like diving in air. I plan to be full cave in the next 2-3 years.
oh, and personally I see no issue with diving END beyond 100' as long as one recognizes and takes into account the issues, plans for contingencies, blah blah. personally I'm comfortable doing short dives well in excess of that, although I will use mix when I am able to. I did get quite buzzed in the quarry last weekend
I have no intention of making a practice of doing 150'+ air dives once I can use mix.
