Fantasea FG7X III S Underwater Housing

Includes Hybrid Vacuum Safety System


Fantasea underwater housings are compact, lightweight, rugged, and stylish - and made of top-quality polycarbonate for any budget. The Fantasea Canon G7X Mark III housing is designed with excellent ergonomics and labels on every button for easy control identification. All controls are within a finger's distance and easy to operate. Another great feature of the housing is that it comes with the Fantasea Hybrid Vacuum System. It provides an early warning if the housing has a leak and peace of mind that the camera is safe while underwater. The Fantasea housings are also reasonably priced and will not break your bank.
