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.
