The P-weight 4 kg is perfect for adding some addition weight to a diving system, either a twinset or a single cylinder. A P-Weight fits neatly inside the 'v' of a backplate and is attached using the same bolts and wing nuts as a backplate and wing system.
P-Weights are an excellent way of placing weight onto a diving system allowing some weight to be removed from a weight belt. In an emergency this means less weight is ditched, allowing for a safer ascent rate whilst still being more buoyant at the surface. P-Weights are also neatly concealed right above a divers centre of gravity making the diver more stable.
