The Ewa-Marine D-CG7 housing is manufactured from double laminated PVC and has an integrated, optically neutral flat glass port. It has a pair of non-corrosive, seawater resistant clamping rails that fit together to form the seal and are secured in place by means of two screw knobs. Rated to a depth of 33' (10 m).

This versatile housing can be used in a variety of applications like sandy or dirty conditions, kayaking, or while swimming, snorkeling, or diving. It's easy to operate the camera because its various components and buttons can be operated through the PVC.

The D-CG7 housing was specially designed for the Canon G7 digital camera.
