The 3lb Lead Dive Weight is specifically designed for scuba divers, spearfishers and freedivers to make fine adjustments to achieve perfect buoyancy in the water. This lead weight is sized to easily fit most standard 50mm wide nylon or rubber weight belts making it versatile for all types of underwater activities, whilst the rounded and contoured design ensures comfort against your body during extended diving sessions. The weight is hardened with antimony to prevent deforming making it six times harder than plain lead ensuring exceptional durability even when dropped or knocked during use, whilst wide belt slots make lacing easy and the recessed strong cross-section protects your belt strap from natural wear preventing clamping onto your belt when dropped.3lb Lead Dive Weight – Buoyancy Adjustment Antimony Hardened – six times harder than plain lead preventing deforming with rounded contoured design for comfort during extended sessions Standard Fit – sized to fit most 50mm wide nylon or rubber weight belts with wide belt slots for easy lacing and adjustment Durable Construction – recessed strong cross-section protects belt strap from wear whilst preventing clamping when dropped Fine Adjustment – 3lb size allows precise buoyancy tuning making it ideal for achieving perfect neutral buoyancy at depth
