Dan, got my new suit last week and love it! Thanks for offering such a top quality suit for cheap...it's the softest and most flexible I have ever worn. I got the 3 mil and it feels like a 1.5 mil or 2 mil suit. I dove in 62 degree water for 30 minutes without getting cold and after taking the suit off was surprised to find I was barely wet! I'm 195lbs and 5'101/2 and the large fits me like it was custom made. I would recommend this confidently to anyone. Thanks again

Fishhound what world record holder? yes O2 toxicity is a problem and it is not so much the O2 amount you bring down with you (it does help) but more the amount you spend while down. You could suck on O2 for half and hour, but, it does not make any difference if you dont know how to minimize your O2 consumption...especially when spearing. The trick David Blaine did were he held his breath for 15 minutes or so was done by him sucking on pure O2 for awhile, but, he sat there motionless for 15 minutes!!
Sucking on pure O2 is NOT a safety measure for swb and it would do you good my friend to learn more about the physiology of apnea and swb. Everyone is always looking to cut corners with freediving or freedivespearfishing and usually it is the younger crowd or those who feel they can make it easier...there is no tricks or secrets or magic pill, what there is is education, expierience, dedication and and most of all an understanding of yourself and what you are capable of all learned in time from the afermentioned. Our sport is already a very dangerous one and many of our brothers and sisters die each year from it, so in my humble opinion it is best to forget about this and simply work on improving your capabilities in time.
Comfort while diving deeper comes in time and becomes more rewarding, if 40 to 50ft is uncomfortable or extremely short bottom times then it is your bodys way of saying I am not used to this and there are avenues you need to work on in order for your body to come to terms with that depth and longer bottom times and it will happen believe me, but, there is no trick whether it be pure O2, eating sodium bicarbonate, massive alkaline diet, baking soda or anything else that will get you to a more comfortable place and enjoyment while spearing than plain old diving...diving...and more diving. Be safe my friend and have confidence that you can get deeper and longer with time.

Learn about acidic and alkaline blood levels and what happens when you dive, when you exert energy, the bohr effect and other things like that and you will see what I mean.

Great info and thanks...the world record holder I mentioned is on the deeperblue forum. I dont want to give his name because I dont want to misrepresent something he said by accident. If you do a search on this topic and that site you will quickly come across it. RIght now I'm very comfortable at the depths described for around 130...and im even very happy with that. I just thought this to be a very interesting topic of dicussion from a physiology standpoint and the fact that there is alot of theory on this but not much actual research. I still have alot to learn and that's why I'm asking questions.

spearing mostly...just thought it could be a safety measure to prevent swb and make you more comfortable while down...just thought it to be an interesting topic.

No need to jump on Davie for making a joke. He is an excellent spearo with great fish sense, and a good diver that we can all learn a lot from. You have to realize that asking about "freediving" with an O2 bottle sounds ridiculous to us, especially after only freediving for a year and not having reached anywhere near your potential actually freediving. What you're suggesting is just not done. However maybe these guys will know something about it http://spearfishing.world/divi…mpetitive-freediving.html

On a serious note freedive spearfishing is risky enough, what you're suggesting can only make it more dangerous. I wouldn't do it. There are a few methods that can be used to go deeper when necessary, variable ballast, a partner that will pull you up with a rope, all advanced techniques for experienced divers.

Sorry to give davie a hard time. I thought he was just just giving the typical scare safety tactics to the newbie to make me just forget about it.I appreciate you guys wanting to be safe but I'm not an idiot going to jump in the water with an o2 bottle or I would have already done it and u would be reading about my dead ass in the paper and not this post. I know I'm no where near my limits but I don't care about that. I just want to be comfortable and very safe diving under the parameters I stated before. I'm very interested in learning more about this. And think about it, if there were a pill that you could take and prevent swb while increasing your bottom time my guess is that everyone would take it. There really isn't much actual research on this in the freediving community or from scientists. A wold record holder on another forum stated that while he thought there were risks associated with doing this in deeper water and steered people away from trying it, he had been experimenting with it and dramatically increased his bottom times. There are also breath hold world records that have fallen under o2 so there must be some benfit to it. Just cant see to find an actual research on this. Seems like the guys playing with this love it but steer people away because they are scared and don't know what the effects are. Anyone wanna volunteer to be a lab rat?lol

Using a scuba tank can dramatically increase your bottom times as well.

I think there is more risk using pure O2.

Thank you captain obvious. No need to reply if you don't have any real info to share on this. ie you have done it or know other people who have or know hte science behind why it's good or bad. Thanks

What are you going to do, swim with an O2 bottle?

no..I was contemplating either breathing pure o2 at the boat for a couple minutes or maybe having a bottle on a line or float to breath with before going down. If I stay under 230 total time under water and under 50ft. I was wondering what the risks/advantages are? would this enable me to stay down a little longer? would it help prevent swb? would it kill me?llol I dont know which is why im asking. I got altitude sickness one time snowboarding and was really winded just walking. After a few hits of an o2 bottle I could snowboard 30 min without being winded at all. I know the situations are different but I have read alot of posts about this on three different forums and the only risk anyone seems to bring up is dwb from increased co2. If im staying down 230 or less is that even a risk? Thanks for your advice. btw-not sure if I want to try this or not yet and if I do it will be under close supervision.

New to the forum and been freediving around a year. I generaly always try to stay on the conservative side of things so as not to take any crazy risks but I am intrigued by using pure o2 for breathing up prior to a dive. I always dive 50ft or less(usually 30) so there should be no issues with o2 toxicity. I have heard that doing this can dramatically increase your bottom time. I have never done it but thinking about experimenting with supervision. My question is has anyone done it and if so what was the outcome? Are there risks? The way I see it from what I've read, you can swb from LACK of o2...so how would more o2 in your system be a problem? I don't know anything about this just looking for opinions or experiences with this. Wondering what you all think. Thanks,

Hey guys(and girls), my name is Kris Walter. I live in hudson Florida which is just north of clearwater and tampa on the west coast. I have been an avid scuba diver and spearfisherman for 20 years and for the last year have really became quite obsessed with freediving. I'm also a fly fishing/inshore guide for tarpon and other saltwater fish and competed for years on espn and fox sports net in pro redfish events as a top competitor. I have dove and free dove every where from louissianna to the bahamas. I only freedive and spearfish for fun and because I'm passionate about it. I wanted to join this forum to meet other like minded people and also learn from people with more experience than me. I'm very into following the safety aspects of this sport since I have 2 beautiful little girls at home. Hope everyone had a great holiday and look forward to meeting some of you...

Kris
