You can't always be a purist. When it's "fish or cut bait," you want the fish, and Humminbird's SmartCast RF10 mobile station is just the device to help you reel 'em on in. You get all the benefits of a traditional fishfinder, plus the freedom and mobility to fish wherever you want. Just hook the supplied remote sonar sensor to your line, cast it out, reel it in, and watch the handy 3.1 x 2.5-inch display to identify your target fish. The sensor gives you a view of the fish, the bottom, and the underwater structure right where your line is, in real time. The unit not only helps you find fish--it also contributes to your boating safety.

The remote sonar sensor uses an internal sonar transducer to collect and wirelessly transmit data to the display. Whether you're casting from the bank, a dock, a kayak, a canoe, or a float tube, SmartCast is ready to perform. Its impressive, 100-foot radius extends down as well as around, giving you an ultra-wide coverage equal to twice your depth (down to 100 feet of water, of course). A one-touch menu navigation controls fish ID, depth range, fish alarm, and sensitivity. The 8 AA battery-powered display itself is lightweight, compact, and totally waterproof and even offers a backlight for night fishing.

Wet Switch technology maximizes battery life by shutting down the display whenever the remote sonar sensor is out of water. The user-replaceable remote sonar sensor gives you around 400 hours of in-water use. An A/B channel option lets you use two remote sonar sensors in the same area at the same time for greater coverage (additional purchase required, sensor model number RF40). The base unit, which supports the display, comes outfitted with an anti-skid rubber bottom. It also converts to a handy carrying case--the unit folds in for protected transport and storage.
