Hi, all. I've moved to a place that allows me to shore and boat dive nearly year-round, so I've decided to buy my gear rather than rent. I'm not very familiar with all the subtleties of gear set-ups. My LDS carries jackets and a ScubaPro back inflate, none of which excites me. I want a small rig that travels well, and I'm poor.
Based on the experience of some dive buddies and internet research, I would like a BPW system, and am leaning towards a DGX package with two second-stage regulators. I'm doing almost entirely warm open water, but some dive sites (lakes, mostly) will be colder, likely in the 50F-60F range. I don't know how all the factors interact, so I'll try to lay it out in a way that's informative.
I weigh 77kg/170lb, and usually carry 6kg/13lb of lead. I usually have only a few squirts of air in my jacket BCD when wearing a 3mm wetsuit. I've been renting, so the gear changes depending on the outfit. I'm given either medium or large jackets. I do not know if I've been given steel or aluminum tanks. The first dive of the day I have trouble staying steady (breathe in, go too far up; breathe out, sink pretty quickly), but I usually attenuate on the second dive and get steadier. I haven't minded any of the regulators I've used other than having the hose pull them uncomfortably sideways. I think the weight belt hurts my back.
Because of all that, a backplate system with tank weights or pocket weights sounds like a good solution for me. I do want to look forward to deeper dives, dives in different latitudes, and (way down the line) wreck diving. On the way, I'm considering divemaster training as a way of subsidizing the hobby.
So, considering all that, how does the DGX with XTRA regulators fit my needs? Can I use the steel plate and forego some lead? Should I just get the D6 regs? Is there anything about the ScubaPro Hydros and dual S600 setup that justifies paying almost double up front? The Hydros comes with 4 weight pockets and a bag whereas the DGX requires purchasing extra, but that only closes the cost gap a little bit.
