Capture vibrant 14MP still images and brilliant 4K video with a ultra-compact camera especially designed for the underwater environment with the ReefMaster RM-4K. Waterproof to 130ft/40m, the ReefMaster RM-4K underwater camera is a game changer in underwater imaging; the housing is robust and designed to be hand-held, tray mounted, or worn on your head, mask or body. Unlike cheaper plastic box-style enclosures included with popular action cameras, the unique ReefMaster Dive housing assures consistent waterproof performance with its "Pressure-Lock" sealing system. The ultra-compact ReefMaster RM-4K goes anywhere and is ready to capture your dive adventure. The shape fits comfortably into your hand or mounts easily to a photo/video light like the Sea Dragon 2000F. With 4K video resolution, your videos will be ultra-sharp and rich in color and the high performance 14MP image sensor will capture brilliant still images. Around the back there’s a high res 2"/5cm display for easy aiming and quick review. The pressure locking thumb-screw seals the camera’s housing down to 130'/40m.
