One of our favourite features on the Nauticam housings is the unique port latch mechanism.
Most modern underwater housings require inserting the port into the housing and rotating the port to lock it in place. This rotation varies from a few degrees for bayonet mount systems to several full revolutions for thread mount systems. In either of these designs, the friction induced by rotating the port can extrude the port o-ring if it is not properly lubricated.

Nauticam takes a different approach. Each Nauticam housing has a bright red port release lever, topped with a safety release button. Rotating the port release lever rotates the locking bayonet tabs while the port remains stationary.
To mount a port on a Nauticam housing:
Because the bayonet locking tabs rotate, not the port, there is no danger of an extruded o-ring when mounting the port. The safety release button insures that the port release lever cannot be accidentally opened.
Don’t forget, Nauticam has port adapters for all the popular brands of ports including Ikelite, Aquatica, Sea & Sea, Nexus, Subal and Seacam. So you can shoot with the most innovative housing on the planet without sacrificing your investment in ports for your existing housing.
