Centaur Gimbal Belt
When fishing off shore for tuna, billfish and other large pelagics in New Enlgand a gimble fighting belt can be an important piece of gear. This one from Centaur fishing is an excellent option.
It is shockingly lightweight and comfortable, but still sturdy enough to handle enormous pressure from enormous fish. Foam backing keeps you cushioned and comfortable the whole fight long. Gimble pin is removable to allow normal rod butt ends as well.
