Travel BCD?

[Anish]

I just finished a LA in the Maldives with my new Dive Rite Hydro Lite and loved it. It's light enough, soft back plate, adjustable straps and dumpable weight pockets. I found the trim to be great. It's minimalist but not too sparse. It has SS hardware, 6 D rings, and is rugged.

I use a Dive Rite Hydrolite for single tank travel diving. It is relatively inexpensive, very lightweight, and holds up well.

60xx alloys are plenty strong enough for mountain bike frames. I suspect if your scooter can pull you fast enough that "they're not strong enough", you'll have other equipment problems too. Like, your regulator getting ripped out of your mouth by hose drag.

I’m not sure that, from an engineering perspective, the comparison to a bike frame is valid.

A aluminium bike frame gets its strength partly from using thicker materials than steel frames, triangular (not round) shaped beams and from the triangular frame design. The forces applied to the frame are compression forces, not pulling the frame apart.

The O or D-ring is a thin cross section of an aluminium frame beam, with the pulling forces being applied stretching it.

The aluminium ring may or may not be strong enough for a scuba scooter application, but I wouldn’t use it on a climbing harness.

Edit: the cargo ones go to 10K pounds but I can't easily find a diving-style one with load rating. Steel ones do 7K pounds, if Alu can hold 1/10th of that, it should be good for scooters.
