The clear case provides a "comfort factor" that is simply not available in any other professional caliber SLR housing. This is not another cheap plastic product. A clear case would be the logical choice if cost was no object. The design requires costly tooling and molding machines compared to a simple aluminum casting or machined product. The final product is less likely to condensation and finish problems that can occur with aluminum. The paint does not chip or fall off of these housings, and the aluminum housing finishers have not figured out how to make their housing clear.

A design can be too small to provide neutral buoyancy underwater. The handle bar removes with two screws for easy packing. The ports remove instantly and allow easy removal of the "O" ring for cleaning. The new "Safety Port Locks" click into position, and can not be accidentally bumped open.

The seal of the interchangeable port system is the only design that allows you to see if it is correct. You can look through the clear plastic and see the "O" ring seal. If it looks sealed it will be sealed. Every other SLR housing relies on theory and hope. There is no way to see if the port is sealed properly on an aluminum housing.

The housing "O" ring seal is a masterpiece in simplicity compared to designs that require stuffing the "O" ring into a groove.

The housing and ports utilizes a unique gear drive sleeve system that allows various and simultaneous combinations of both manual focus and zoom control for many lenses.
