SeaLife ReefMaster RM-4K Ultra-Compact Underwater Camera

The SeaLife RM-4K features brilliant 14mp still images and vivid 4K video in an incredibly small package that's easy to hold and use alone or with attached lights like the SeaLife Sea Dragon. The ultra-compact removable inner camera and robust external housing mounts easily to a light tray. The easy, 4-button control system makes catching the action an effortless process. The ReefMaster offers WiFi sharing ability, so you can wirelessly preview, download, and share pictures & videos to a smartphone or tablet.

The easy to hold ergonomic housing was specially 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 a video file or series of still images.

The compact RM-4K is easily expandable with popular SeaLife accessories, including one or two Sea Dragon 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.
