There are many positive things that freediving can do for tech diving.
Many of the top tech divers in the world are also freedivers: Tom Mount, Brett Gilliam, Billy Deans, Kirk Krack, Jay Styron
, are just a few of the people who practice(d) both.
It will helps you with your air consumption for one. I can make a scuba tank last a very long time- without skip breathing! It also helps you manage those out of air situations with much less stress than the average bubble blower. I have recently started practicing exhale statics. I think that these would be awesome for a scuba diver to practice. That way you know you can handle anything umderwater, even if you did just have your regulator ripped out of your mouth after a full exhale.
Ted is right about my wanting to dump all things tech.
I have no more real desire to strap on all of those tanks when it is possible to train to hit the same depths without all of the extra clutter- not that I'm there yet.
I really like how much less space, and money, my freedivng gear takes up than my tech stuff. I recently bought a new digital camera and housing with the money I got from selling off a few stage bottles and regs.
I also like the extra time I can spend in the water playing around compared to the strict time scheduals imposed by any type of tank diving.
Another big jolt for me was that I can't afford to keep up with my tech diving buddies anymore, new kid at home
, and money is the only reason. I was invited to Dive the Gunilda, really awesome shipwreck, this summer, but simply can't afford to go. I know that I am as good, or better, than any diver on the trip, but I can't afford the trip. I CAN afford to do as much freediving as I want and should be able to get a new speargun this summer on top of it.
In my pre-trimix days we did some deep air dives that might have been cut short by the amount of air that we carried. I know that I never had a problem because I was able to rest and slow everything down to a freedivng static level during deco and came up with plenty of air whereas I might have run out otherwise. In fact, I have had to share extra air with other divers, and instructors, more times than I can count- no they weren't my buddy either. :duh
Another "instructor" that I had the misfortune of diving with, once, couldn't even clear his ears to get to depth. I am not talking about a cold or any kind of sickness. This guy just couldn't clear! I did one 200' dive with him and couldn't believe how much time he wasted getting to depth. In the end he ran out of deco gas and the third diver with us had to bail him out with an extra deco bottle. This guy was a mess who never should have gotten a trimix or instructor card- Ted knows who he is.
Air consumption, water comfort, equalizing, proper wieghting, breath control, are all things that freediving can improve.
Sorry for my rant.
