The easy to hold ergonomic housing was especially designed for use underwater, while the housing is easy to hold and use even with one hand, the tough enclosure also features a unique closing system – a “Pressure Lock” thumb screw that exerts the optimal amount of pressure on the housings O-ring seal. The waterproof housing encases the small inner camera, and also stores a powerful drying agent called “Moisture Muncher” next to the camera that prevents internal fogging caused by heat and humidity trapped inside the housing.

With the expandable memory of the ReefMaster RM-4K, you can use Micro SDHC memory cards up to 128GB, ensuring you have room to shoot & save all of your video content. It also has a time lapse function – shooting at set time intervals and saves as video file or series of still images.

Lighting is easy, use the ReefMaster RM-4K with Sea Dragon constant underwater LED photo/video lights (or other LED light sources). There’s no flash or cable to sync to an external strobe. Simply turn your light on and adjust the intensity based on the subject, conditions and distance.
