Need to check your props or hull, examine bottom structure or scope out a narrow channel? Let HydroView, a remote-control submersible robot, perform these tasks for you. It comes complete with an HD camera, waterproof carrying case, 75 feet of cable (longer lengths available) and LCD display for $3,995. Too pricey? Check out the AquaLens ($475), an underwater camera that attaches to a pole to become your underwater eye. It has a 15-foot cable and a 3.5-inch display that straps to your wrist. Both are from Aquabotix Technology (aquabotix.com).
Personal AIS Rescue Alert
How do you find someone who has fallen overboard? The Kannad SafeLink R10 ($299, kannadmarine.com) is a personal Automatic Identification System transmitter with built-in GPS that can be worn on a life jacket or fastened to clothing. When activated, it broadcasts an emergency alert that places an AIS icon on your navigation screen. The exact location and distance of, and bearing to, the person in the water are also displayed. The R10 is not an EPIRB or PLB and does not alert first responders unless they happen to be within four miles of your location.
