Are there any entry tech courses that include Trimix?

LOL. Dude relax. You are clearly an accomplished mix diver, and I am not. It'l be another 100 deco dives before I am comfy going to mix. I just happen to feel that adding helium to the equation too early is dangerous.

But then, I'm an old fashioned kinda guy. Some guy on another board with less than 25 dives was asking about extended range and mix. I guess it's the "new thing". Mix is the new EAN. I guess CCRs will be the new doubles soon.

I think this is an east coast/west coast difference in thinking. Perone if I read your previous postings right, you are in florida doing warm water/cave diving while Rainman is west cost, cold water diver so both of you are talking at a bit of cross purposes.

Perone for your dive you probably figure to drop your O2 bottle off almost immediatly and any stages as you expend them as you are in a cave. Your deco is nice and orderly on a log in 70 to 80 degrees of water. An immersion time of 2 hours and 24 minutes is not totally outside of reason.

Rainman, for your dive you are off a boat or shore. You have to drag your stages through the surf and carry every bottle with you the entire dive for a much higher work rate. Your water temp is 49 to 54 degrees. You could have 10' swell going over your head which makes the 100% more difficult to use. An immersion time of 2 hours and 24 minutes is very serious and the dangers of hypothermia are much greater.

Yes, you're right. Cave divers sure do have it easy.

I don't know what I am going to do when I go up to the Great Lakes this year.

Well I do think there are two different "prejudices" at work...

1. Is that people don´t get a decocert unless they can hold their stops. Since they can hold their stops, "helium is your friend".

2. Is that people can "muddle thru" an adv. nitrox or deco procedures course. Tmx is where people "really" learn to dive. A graph of a "decocert-holder" looks more like the EKG of a beating hart than a flat-line, "helium is not their friend".

1 and 2 will never see eye-to-eye on this...Personally I hope that instructors don´t certify people who can´t hold their stops...

I did a dive last year with a guy who had an extended range card, a trimix card, and a cavern card (all same agency and instructor) and who I'd personally seen do a dive to 160+ ft.

When we did a shallow dive to about 75ft and came up, he couldn't hold 15ft and laid down in the silt to do his stop. There was no ascent line at this site.

Not an accomplished mix diver, just a guy who thinks there's a lot of misinformation out there about helium. I think people should pursue training from a reputable instructor and build a good experience base before pushing onto the next level...but there is never any need for misinformation.

 

[PerroneFord]

Ok,

Could we get at that misinformation for a moment? I am not a helium diver. I'm around it a lot. Many of my dive buddies use it for a lot of their dives. I have talked to a number of instructors about it including the ones I train with.

What do you feel are the most prevalent bits of misinformation that are out there about diving helium?

Maybe he was eyeballing a flounder?
