ABSTRACT:
A shark deterrent device is disclosed. The device comprises at least two hollow cylindrical shafts, a tip, a twist-release mechanism, and at least one self-lock mechanism. The tip may be replaceable. The shark deterrent device is a retractable unit that is easy for a diver to carry and stow, and yet can be extended in order to deter a shark. The device is unlocked from its retracted position by twisting a collar, thereby unlocking the concentric shafts and allowing the unit to be fully extendable by hand. Once the unit is fully extended, a self-lock mechanism lock the unit to prevent it from retracting during use. The unit has a handle formed at one end of the outermost cylindrical shaft and a tip at the opposing end of the innermost cylindrical shaft. The tip may be replaceable and removed, and other useful tips may be attached.
