Technical Spearfishing Technical Scuba diving is generally defined as going deeper than 130 feet. You must have the proper training for this extreme aspect of spearfishing. |

How deep on air?
OK, for you deep divers on here. My setup is almost complete.
LP120 cranked to 3600psi 30cf pony What is the deepest you guys go around here with this kind of setup. I will be getting a couple of 30s for 80% scrubbing. I'm thinking 200-220 feet os so. What is the best way to build up to those depths since most dives are solo. |

I'm not a diver, but I thought solo was a no go....

Re: How deep on air?
200'with 2 of the guys here.
180' with a couple more. 155' with a few. 168' with my wife taking pix. The point is to be able to function safely and within your abilities.Some conditions severely exacerbate narcosis such as current increasing work and CO2 load,constriction due to wetsuits in the cold water,dark conditions etc.... Helium is definitely better past 200' but there are a couple guys here who have been WAY past 200' spearfishing on air commercially and recreationally.Training is nice but quite a few folk with a lovely collection of cards are inept even after the best training while others take to it like a duck to water.

Re: How deep on air?
We dive to spearfish. It is counterproductive to go down in pairs. Scares the fish.
Thanks Mike. Quote:

What is your lost gass bailout strategy? What is the END that you plan on maintaining at your max depth? What is your planned and contingency bottom times and depths? How do you plan on monitoring your CNS and your OTU's for this dive? Why are you using 80% instead of 100% o2? Do you know the difference in microbubble formation and nitrogen intake vs pure Oxygen to choose 80% as opposed to 100% o2? Any macho wannabe idiot can grab a tank and breathe from it, it's knowing what to do when the crap hits the fan that separates calm well trained divers from Macho wannabees who are trying to compensate for their shortcomings. Based on your self description of diving and unwillingness to take a class because you're too cheap, I would safely say that the max depth you should go to is about 12 to 15 feet! Have a Macho day... Vroom Vroom....

But it's obvious from his post that he has decided that the rules don't apply to him, and that he can teach himself just fine. There's a saying in the tech community.. "You don't know what you don't know" If this guy would have learned the basic math in a NITROX class, then he could figure out the MOD of air on his own! See my point? That's why I answered the way I did. Besides, my answer was right in line with information he should know to do these kind of dives. Besides, I'm not about to give this guy the information that he needs to go kill himself.

Actually, I'm in the springs with doubles, 1 stage and 1 o2 bottle. We were setting up to do a 2 hour cave dive. You're a dumbass, go figure!

If that's him on that bike, he can ride the shit out of one. I would guess he could take the stress of problems underwater. |

Re: How deep on air?
LOTS of variables on deep air.
Step one is to find out what YOUR CNS trigger symptom is and be able to identify it early enough to turn the dive safely. YOUR symptom will be different than mine, and mine is different from anybody else I've ever gone deep with. One girl I dove with in The Tongue tasted cinnamon rolls as her warning sign, so be aware that it can be ANYTHING. The dive turns at the FIRST hint of the symptom! this symptom will be consistent for YOU, but the depth it strikes will vary with a host of variables from how hydrated you are that day to how much sleep you got LAST weekend! Most will not do enough deep bounces in a lifetime to determine what their symptom is, as it may take a hundred or more dives in benign conditions to sort it out. Hunting in any form is NOT benign conditions! The He mix divers avoid the problem by changing the diluent gas. Oxtox is another problem not related to the CNS issues, with it's own set of variables and rules. As posted before on other threads deep air for me is based on simple math. If when counting my breaths deeper than 150' I run out of fingers on one hand, or my symptom shows up, my dive is over. Hunting deep on air in any mode but a true bounce IMNSHO is begging to become a statistic, usually without a body to bury.
