jonnythan:Because a forum isn't real life. In reality, those $1000 flashlights represent a TINY TINY minority of the dive industry.
Ok so your right about that. But divers in general do spend a lot of dough. The reason I pose the question here is that many of the divers here actually use trimix/triox, have taken the course and might know some reason the average nitrox level diver couldn't just as easily add a wee bit of helium. I havent heard any reasons along those lines that are compelling. Cost is obviously a hurdle for some but a whole lot could afford it if they wished.
