ABSTRACT:
A sleeve air gun for releasing compressed air into water. The air gun housing has a chamber enclosed with an end cap. The end cap is engaged with the air gun housing with a retainer that is light weight and expedites the engagement and disengagement of the end cap and housing. The retainer can comprise a light weight ring that engages the housing and end cap. The retainer uniquely permits larger diameter air guns to be constructed without disproportionately increasing the weight of the air gun. The larger diameter air gun expedites the discharge of compressed air from the air gun, which maximizes the acoustic pulse generated in the water.
