arrick c Can I mount this on other brand's BCD or a harness? Will this hold a bigger bottle like a 6lb pony bottle?
GREGORY P yes, you can mount this on any BC, however, it will not fit any cylinder larger then the Spare air bottle. Your 6lb pony will not fit!
MICAH B I didn't mount this on my BCD. I put it on upside down and attached it to my tank. It is a designed for the 3 CF bottle and it a snug fit. I don't think it will fit any bigger bottles. Hope this helps.
LUKE A It uses grommets to attach so if the bc has grommets you can probably make it work. It will not hold anything larger. I've been using it for 2 years and due to the weight of the spare air out of the water, the pocket it tearing at the top grommet but still holds.
