Abstract

A laser beam sight incorporated inside a spear gun. The device has a capsule positioned at the tip of the spear gun, the capsule includes a light source preferably a laser diode and the battery powered, a magnetic switch in the handle (close to the spear gun trigger) to control the laser device, a cable to connect the capsule to the magnetic switch, and an optional floating bar located inside the spear gun barrel to balance the spear gun's weight in the water.

What I claim as my invention is:  
     
         1 . A light beam sight device located inside of a spear gun, the device comprising of: 
 a) A magnetic switch to activate the light beam mean.    b) An elongate capsule containing the light beam source and its power source.    c) A cable that attaches the capsule mean to the magnetic switch mean.    d) A cylinder of floating material inside the tube of the spear gun    
     
     
         2 . The device of  claim 1  wherein the magnetic switch includes means for affixing the switch in ‘on’ and ‘off’ position.  
     
     
         3 . The device of  claim 2  wherein said magnetic switch means is adapted to turn on the light beam in pulse mode operation.  
     
     
         4 . The device of  claim 1  wherein said the power source mentioned above is composed of a plurality of batteries.  
     
     
         5 . The device of  claim 1  wherein said capsule mentioned above is made of reinforced plastic.
