Weight belt idea - what am I missing?

[lowviz]

True.

Ideally, just a couple of pounds more than the total weight of your gas when you splash.

Mako has a new weight belt that's designed for heavier weight totals. It's still rubber, but not as stretchy as the other one. I have my two 10 lb shaped weights on one, and I really love it. It still has enough stretch to compensate for depth, but it's not as soft as the older ones are.

Whether a 1lbs belt or 100lbs belt, I can tighten either without difficulty if I'm HORIZONTAL.
Also the belt doesn't stretch, it is your exposure suit that compresses with depth.

One thing you're missing is releasing slack when you're ascending. Nylon ratcheted down is going to need to be loosened unless you want to end the dive in a corsage.

This means your ratchet needs springs, small parts. Lots of metal integrated into moving parts costs money.
Not a huge market for a problem that doesn't really exist. There's already a solution to your problem that's completely free of charge.

And there's even a solution that costs money. It's called BC weight integration and rubber weightbelts.
I'm a fan of splitting the load.
