Unlike scuba diving, a freediver can’t stop to adjust a loosening weight belt due to wet suit compression at depth. The Salvimar Elastic Pro Rubber Weight Belt with classic Marseille Buckle (positive lock) allows the serious diver to snug up the belt at the surface and forget it while diving.
The choice of a weight belt for freediving is of essential importance. A freediver descends underwater, head first, and remains vertical until they reach their goal depth. The pressure decreases the volume of your wetsuit as you descend, and only an elastic belt can be tight enough to respond to this.
