ABSTRACT:
The invention relates to an underwater catapult in which the arrow is propelled along the length of the barrel. The inventive catapult comprises a system which can be used to launch a gun arrow with bungee cords along the length of the shaft. The system comprises fixed or moving pulleys which are disposed on each side at the head of the gun and fixed or adjustable anchoring points (lugs, recesses) which are open for loading under the gun and which serve as support points to the tension cords for the movement thereof. The aforementioned pulleys can be used to load the large-sectioned bungees which are linked to variable- and standard-length bungees under the catapult for loading and power utilities. The catapult can be used to store more energy and use the integral characteristics of the elastic rubber. In this way, underwater hunters can equip themselves with an arm which is very powerful, accurate and recoil free compared to those currently available.
