Extremely durable ‘pass-thru’ style divers lead block, coated with extra strong vinyl covering. Optimally used with belts and in conjunction with weight retainers. An environmentally friendly solution to maximise comfort during diving as the tough coating also seals the lead inside to avoid any possible water contamination. Standard 2 inch/50 mm webbing weight belts pass through the centre of the weights, which can be easily combined together and any movement simply stopped using 3 bar buckle weight retainers. All edges are rounded and shaped to form perfectly around your waist.
