The CA500 Camera is the ultimate underwater observation system. This thru-hull camera will display what is directly below the boat, making it an ideal underwater fishing camera or underwater video surveillance/ safety system. Simply connect the single cable to a Raymarine E-Series Classic, C-Series Widescreen, E-Series Widescreen, or G-Series System and spy on the underwater world. The CA500 is one of the lowest Lux (0.01) cameras available today-all protected by a sapphire viewing window that resists scratching or cracking. The retractable housing with valve is available in plastic and allows for easy servicing and cleaning of the camera while the boat is in the water.
