This thru-hull camera will display what is directly below the boat, making it an ideal underwater fishing camera or video surveillance / safety system. Simply connect the single cable to any display with a NTSC input and spy on the underwater world. Airmar has combined the industry renowned Airmar housings with one of the lowest Lux (0.01) cameras available today - all protected by a sapphire viewing window that resists scratching or cracking.
