Ok, I will spill my guts and get all you guys pissed at me... but oh well, you asked for it... My problem with GUE in general is the way they try to brainwash you and tell you exactly how to dive... Its like a whole bunch of little Hitlers diving around the caves in FLorida, and elsewhere now. I dont like being told that in order to take a class, my equipment needs to be of some certain type and i may have to buy new equipment. I have done some technical diving, and I am sorry, but I love my poseidons and my high pressure tanks. I also like my Mares Quattro fins. ANother thing that drives me nuts about GUE, is they feel that eveyone should use Trimix for any dive deeper than 100 feet. I think that is ridiculous. I have dove deep on air, and it gets you ready for the Trimix class, which I dont plan on using under 150 feet. Everyone has their opinion, i guess. Its just we get their students in our shop to fill trimix to do the Crane wreck at 145, and they say, oh thats what GUE does, so thats why we use it. They cant explain it. Maybe its just the ones i deal with in the Boston area. MAJOR ISSUE WITH GUE: About two years ago or so, we had a guy from my area go down to Florida and take a Tech 1 class. He then got fills from us for 50 % o2 for deco. About 3 months after that , he comes in and says he wants 100%. I ask him, did you take another class??? He says no, GUE just changed the standards and now, he can use 100% o2 for deco also. SO, after a class where he only used up to 50% as a deco gas, now, they just decide to let everybody use 100%. I dont get that how GUE can just change the standard, and without any further training about high o2 deco mixes, he can now use it. It blows my mind. :bonk: That, in a nutshell, is why i dont like GUE and I never will.... GO IANTD!!!!!
