Aquatech P-50Ex (50mm Extension Rings)

The P-50Ex 50mm Extension Ring from AquaTech increases the length of compatible P-series PD-65 and PD-85 lens ports by 50mm to allow them to accommodate longer lenses. It mechanically seals onto the housing and the port screws into the ring. This extension port is compatible with the AquaTech Base, Compac, Elite, and Delphin underwater sport housings.
