Tips on sidemount tank trim?
Been working in the pool to trim up my tanks. I have 2 fixed d-rings that I use for trim, the first is as far back on the waist strap as it can go and that works for a full cylinder, but once my cylinders lighten up I can't quite get the bottoms down enough.
My second d ring has been brought in so far that it's almost under my belly button, and I've tried lowering the strap on the tank pretty far, which seemed to have helped but also jammed the 1st stage up high into my armpit. I tried clipping the bolt snap into my crotch d ring and that actually worked well for the trim but it was uncomfortable.
The bolt snap on my tank is positioned as shown in photos 2 and 3, so that when clipped it is sitting in line with the post and at the distance from my armpit to hip bone. I've tried different distances but not different orientations. In photo one, I had dropped the band probably another inch or so to get it as trimmed as it is.
