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. For optimal results, especially when shooting 4K video, use Micro SDXC Class UHS Class 3 (U3) or Video Class 30 (V30) memory cards.

The compact RM-4K is easily expandable with popular SeaLife accessories, including one or two Sea Dragon Photo/Video/Dive lights, and available 10x close-up or super macro lens. Its 2.0” TFT color LCD screen creates a sharp and easily visible display on the small camera.
