Why guess where to find fish? See exactly where they're hiding with STRIKER Cast castable sonar. Just download the STRIKER Cast app, pair your mobile device with the sonar, and go fishing in minutes. Cast from shore, dock or watercraft, and reel back in to locate and display fish on your smartphone or tablet. The sonar streams wirelessly from up to 200' away, working in freshwater or saltwater (and even below ice) to show you fish and structure in crisp, easy-to-interpret detail. Select from easy-to-understand traditional 2-D sonar and ice fishing flasher modes, with setting adjustments for gain, range and more. Access to the online Garmin Quickdraw Community lets you download maps with 1' contours so you can remember the best fishing spots.
