Just curious but does UTD not put a strong emphasis on removing entanglement hazards and clutter where ever possible or is this a personal thing? Haha i missed the fine print the first time through :dork2:

Patton WMD (1967) Experiments on the convulsant and anesthetic effects of oxygen Showed the narcotic effect of oxygen on mice. The ppo2 were extreme but anesthetic properties were observed. Once again the literature is sparse. Hard to prove the case of the narcotic effects of oxygen one...

double post :(

Due to the inconclusive nature of the studies of the narcotic effects of oxygen some modern tech agencies play it on the conservative and conclude that oxygen is narcotic for END calculations when diving deep with trimix. For example on the ambiguity of the subject here is a double blind...

My point had nothing to do with deep air. I was just looking at spearboard and there appears to be a disproportional number of "am i bent" threads and there is a large number of self taught divers. This also seems to be a community that pushes deep air. Correlation doesn't equal causation but...

Isn't that sort of like saying that car crashes cause the most fatalities to drunk drivers and not alcohol? Seriously though unless that study only included deep divers then I doubt the majority of fatalities even happened beyond a END of 100' which doesn't really help your argument. Do you...

No clue but the number of "why am I bent" or "Am I bent" threads on spearboard seems disproportionally then other tech forums. If it is though it might not have anything to do with deep air but more the lack of training. So many guys talking about being self taught to dive deep it's scary.

It's like you said earlier. Everyone has their own perspective on what is reasonable and what isn't reasonable on deep air. For some 200ft is just another weekend of spearfishing but for me it's crazy. I really just don't understand the drive for spearfishing in general and it seems like...

Here is an interesting DCIEM study looking at the nitrogen narcosis adaptation rate of experienced divers. Rubicon Research Repository: Item 123456789/2199 11 divers where taken to 54 meters and 3 meters and were given a tasks to preform, these tests were preformed over 5 consecutive days. The...

Can't speak for an GUE or UTD instructor but I would imagine they would say something along the lines of how kludgie it is. One issue i see is if your inflator hose is leaking or if you have to disconnect it all together you lose your back up and thus end the dive. Depending on the dive loss...

Wings made for doubles used for a single tank are really floppy and hard to get use to. I would recommend getting a single wing first. Get a double wing when you are ready for doubles. The single wing can be your vacation and loaner wing for friends.

That's the way they should respond. I had a dive buddy that had a doctor with limited knowledge of decompression injures over analyze the symptoms and decide that a chamber ride wasn't needed. 6 hours later released from the ER with no change in symptoms. Goes to a navy facility and a SEALs...

For gas planning it's better to know your SAC range. One day you may be at .6cuft a minute after a long break maybe .7. Plan on the conservative side. So if i am planning with this SAC range i would use .7. When you actually calculate dive time it's usually easier to use 5 mins instead of 1...

AGE and DCS symptoms overlap. AGE and DCS treatment is the same. Distinguishing between the two is worthless for a first responder and most in the medical field. Paramedics and the first doctor on the scene doesnt give a crap what you think he has. They only need to know from you that he...

When's the first trip for tech 1 level dives in the great lakes and more importantly can I come? :)

Nice report and grats! :yeahbaby:

What are we arguing about again? lol :D

My wife might be interested depending on costs. Also, dont forget that Ed Gabe isnt to far away so it might be easier to get him to the quarries. Regardless of what you have in mind I'll try to be there. Oh, congratulations on the Tech 1 pass :) Mark

Thal would you be happy if I replaced the term DCI with AGE in all my posts on the topic? lol AGE is a very common diving injury. Divers are taught to keep their air way open from day one yet AGEs still continue to happen. Why is it assumed an inexperienced diver will remember to keep his...
