Ontario Diver once bubbled...
But what kind of diving are you going to do?
Both of these regs are top notch high end regs. But they cost $$.
*IF* you see your diving being restricted to 30-50 ft shooting pictures of fish - then save some money on the reg because there are several dozen less expensive regs that will serve you very well.(snipped out middle bit for brevity)
Have you thought about asking your LDS if you can test them during your AOW course?
Type of diving projected: Recreational looking at pretty fish and likely also work (looking at less-than-pretty benthos and point pollution sources).
I used ScubaPros during my OW with... mixed results. (have to go back and get the model designations). First reg was awful - and assistant instructor blew off my concern about poor airflow in the classroom by telling me it would be better underwater (last time I'm ever going to believe that one).
Hit the pool and couldn't get anywhere near enough air through the wretched thing. Thought it was me, nearly walked out (well, swam). Ended up trading gear with head instructor (same model regs, different maintainence schedule!) found I liked them (though not his BC- it was far too large
) and he found that the particular primary reg they'd given me for the course was digestive endproduct (and the secondary was only marginally better).
The main envelope I plan to push is temperature, and possibly time (long, shallow dives in rivers are likely to be in my future). I've read that some regs just can't cut it in four degree water and below-freezing air T's. Will also need something I can clean up for nitrox. I'd also rather wait and buy a good regulator as opposed to buying a cheaper one now and find i have to replace it. Your input, and that of those others that dive in really cold conditions, is greatly appreciated.
Cold, nitrox-cleanable, adjustable, purge in nice obvious place on front, high airflow-capable and works upside down are what I *think* I'm looking for in a reg (and octopus). Maybe there's soemthing else I should be considering? Cheers! cat
