The invention pertains to a speargun, comprising a barrel having an oblong body and a spear track for directly receiving a spear, the spear track being formed as a channel on the outer surface of the barrel, a handle unit connected to the barrel, and a trigger unit for releasing the spear through activation of a finger trigger, wherein the barrel is constructed as a single piece having an oblong barrel body comprising a hollow interior space, wherein a reinforcing bar is provided inside the hollow interior space, the reinforcing bar running essentially a length of the barrel body. The invention also pertains to a speargun wherein a housing containing the trigger unit has a window through which the trigger mechanism of the trigger unit is at least partly visible from an outside and a speargun wherein fixation means are provided for fixing the handle unit in different positions along the barrel.

An arrow gun is provided having a controllable retention force on the arrow. By setting the retention force on the arrow, increased energy from motive compressed gas can be imparted to the arrow. The arrow gun also includes a damping coupling for reducing vibration of an unsupported length of the barrel.
