I'll let you know as soon as I get one. They're being delivered late this month or next. It's a free diver's safety vest. The "airbags" are triggered by depth or time. Pretty high tech.
Weights....that's kind of based on what depths you're diving, or spearing. If diving beyond 60 feet, you want to be neutral at about 25-30 feet (with a full breath) If diving in 20-30 feet, maybe neutral at 10-15 feet so you can easily lay on the bottom and hide. Being neutral at 15 feet or more helps you surface even if you've blacked out. (the best way to be safe is never free dive alone so your buddy can grab you and get you to the surface)
I don't think the vest itself increases your buoyancy. It may actually be slightly negative with the computer and gas bottle. I"ll know more as soon as it arrives.
You're probably right, I didn't consider the hardware. In terms of weighting routine, I'm with you. Usually wear a 3/2 WS, and with that, if I'm diving anything deeper than 25ft, I go extremely light, 5lbs, so + rubber belt and equipment probably about 7lbs.

I got the Scubapro Cruiser snorkeling vest for my last trip and really liked it. Most of the time I just keep it completely deflated and it feels like I am wearing a vest made of wet suit material (the vest does not have crotch strap). If needed I could very quickly blow it up with the attached air tube in just a couple breath. It does ride up slightly when filled with air but not bad and again most of the time I just keep it deflated - it is more for peace of mind and extra safety when I go off snorkeling by myself.
Works when you're at the surface and conscious, but what if you're 'down 'n out'?? Just saying ...
