Recreationall TRIMIX

[puddlejumper1]

Now I am real confused here so some one help me out? First thing that seems to thrown about is that technical divers don't want trimix taught to recreational users because they don't believe that He has a place below 130-100'. who is spating that happy crappy around. All of the Trimix divers I know will mix He for these dives. What I am real confused about is several misconceptions that I have just read. First what the he.. does anyone need with a He analyzer? No offense Jon but that is the worst load of ... well I digress. Lets take a simple assumption and assume that I old Joe Schmoe the recreational diver wants to dive to 120' PO2 of 1.4 (he can either have a good old aluminum 80 or a set of nifty PST 130's that his local LDS convinced him were the bomb). Now he wants a fill of good old 30/30 (the dirty mix). Lets assume that his LDS (or him if he is filling himself) screws up big time and flubs the He setting it at 13% instead of 30%. Big deal? Who the heck cares? A 30% He is only going to give him an END of 75' or so. Now that big He screw up of 13% is going to give him an END of 100'. Decompression obligation should be none since he is recreational and has not been taught deco procedures. So what if they screw up and add to much lets say an END of 30' or 59% He. Again so what he just built a deco obligation of 3 minutes at 20' Jeeze isn't that the 3 minute drill. Now if any one can screw up that bad the 02 is going to bad. Just take them out back and shoot them. Stick with analyzing the 02 and leave the $700.00 He analyzer at home. Though I agree that a LDS should have one with the idiots they have working the fill station. The second thing is what this will do to Recreational diving. Short answer not much. I can take a whole 12 minutes diving at 120' on a 30/30. That includes ascent time down but not the 3-4 minutes up. Adding He is only going to clear the Narcosis not make the dive longer. If they are going to run this than it needs to be with Deco or you are just inviting trouble with divers who will push the limits and start to deco with out knowing what to do. Of course since my highest card is PADI rescue what the heck do I know? After all I am just a stroke. ;D
