 This style of harness may be off the shelf from an original equipment manufacturer or retailer, or home made, as most of the parts are freely available or relatively simple to make.In the UK, cave diving was an additional skill learned by cavers to explore flooded parts of a cave system, rather than divers choosing to explore caves.The early equipment was little more than cylinders fitted with belt loops and slid onto the standard caver's belay or battery belt along with any extra weights needed to achieve neutral buoyancy, and a caver's belt mounted battery pack.
