The 5-inch STRIKER Plus 5 Ice Fishing Bundle features support for ClearVu scanning sonar and includes an ice fishing transducer for crisp, clear fish arches and excellent target separation. Built-in GPS and Quickdraw Contour mapping software let you find and mark your favorite spot and return later. Includes rechargeable battery, charger, tilt/swivel unit mount, foam float and a portable carrying case for it all. This transducer is designed for ice fishing. CHIRP sends a continuous sweep of frequencies, ranging from low to high, instead of sending just one. When the frequencies return, CHIRP interprets them individually, gathering a wider range of information for crisp, clear fish arches and excellent target separation. The wide 16-24-degree beam angle covers a large area in the water, so you know what’s coming. Nobody knows the waters you fish better than you and your fellow fishermen. While you are fishing the depths, Quickdraw Contours mapping software creates HD fishing maps of the places you’ve been. No special knowledge is required. Now you can store up to 2 million acres of your Quickdraw Contours maps with 1’ contours. STRIKER provides you with both a fishfinder and flasher all in one unit. Anytime you are stationary fishing, such as ice fishing or jigging for crappie, the built-in flasher will show your jig or weighted bait and the depth of fish as they swim into the sonar beam.
