A diving accessory is disclosed. The invention is comprised of a compact, lightweight fishing spear having two parts: a hollow main tube and a barbed spear. Said spear can be stowed inside the tube and the entire apparatus clipped to a diver when not in use. The invention can also be used as a poking stick (for self defense against large sea creatures), a tickling stick (for prodding prey out of small spaces), and as a camera monopole (by using the onboard shoe mount). An objective of the invention is to provide a compact, spearfishing device with multiple functions to enhance the diving experience.

The invention relates to a speargun handle (1) having a reinforced trigger guard (5) which creates a chamber (6) in which there is a trigger lever (7). The handle (1) has a retaining member (10) with chambers (12) surrounded by a non-slip retaining cover (11). It also has a loading aid (17), a front end (23) for fitting a tube (2), incorporated deflectors (25) for lines and a line holder (32). The handle (1) further comprises a reverse trigger mechanism, wherein the trigger lever (7) is located outside the cartridge (26). The retaining hook (27) may alternatively have a notch for a pivot pin (38) which receives the developing stresses derived from the shaft's (4) launching.
