Why guess where the fish are hiding? With the wireless, throwable Striker Cast fish finder, you can see the exact location of the fish. Download the Striker Cast app, pair your mobile device with the fish finder, and head out fishing right away. Throw the fish finder from the shore, dock, or boat and start reeling it in. The fish will appear on your smartphone or tablet screen. The fish finder transmits data up to 60 meters away in fresh and saltwater (and even while ice fishing). Fish and underwater objects are visible in the app's sharp, easily interpretable image. Choose an easy-to-read traditional 2D sonar mode or an ice fishing-specific flasher mode, where you can adjust sensitivity, depth range, and more. To remember the best fishing spots, you can download maps marked with contours every 0.3 meters from the Garmin Quickdraw web service. Striker Cast GPS models feature an internal GPS, allowing you to create your own maps with 0.3-meter contour intervals using Quickdraw Contours software. Uploading new maps or sharing your own maps on the Garmin Quickdraw web service is easy.
