The Princeton Tec Shockwave Rechargeable Underwater Torch is a powerful 20 watt torch that is ideal for underwater use. With NiCd battery technology and halogen lighting, this torch provides a bright and reliable light source. Its rechargeable feature makes it a convenient and environmentally friendly option. The shockwave model is known for its durability and the sleek blue colour adds a stylish touch to this practical and versatile torch. The rechargeable battery can be replaced with 8 C cells to give a longer burn time. Torch is negatively buoyant and comes with wrist lanyard and foam lined hard carry case. The battery was still working but is now out of power and the torch has been opened to check the battery so oring will need cleaning and regreasing before closing the torch again tightly. No responsibility is taken for leaks as I know it was waterproof when last used.
