i went to my local dive-shop and purchased a belt (about $10.00),it comes with a plastic buckle that i replaced with a metal,spring loaded buckle($25.00),it stays on tight and will not rust.
I made a simple rod holder out of a brass ring,covered it with electrical tape and hung it off my buckle,i can place my rod through the ring and the butt sits inbetween my legs.It really helps when releasing fish(great for pencil popping too).
