Abstract
A spear gun includes two spears disposed in laterally spaced relation to one another. A separate trigger is dedicated to each spear. Each spear is received within the lumen of a forward spear guide tube and a rearward spear guide tube. Each forward spear guide tube includes a laterally extending post to which is attached the forward end of an elastomeric member. The rearward end of each elastomeric member engages an inclined notch formed in the trailing end of its associated spear. The trailing end of each spear is notched and the notch is engaged by a mating notch formed in a pivotally mounted detent plate. Pulling a trigger pivots the detent plate so that the notches disengage and the bias on the elastomeric member unloads to propel the spear forwardly. A safety latch prevents pulling of the trigger by preventing pivoting of the detent plate.
