Take the guesswork out of ice fishing with the Ice Helix 7 Sonar GPS Fishfinder from Humminbird. Its high-speed LCD digital read-out shows your exact depth, and there's also a latency-free digital flasher and customizable graph view with up to 8X zoom.
This fishfinder utilizes DualBeam Plus sonar, which offers a narrow beam for high detail and a wide beam for larger searches. Additionally, SwitchFire technology provides finely tuned returns on the 7" LED-backlit display.
This system has a RMS power output of 500W and a peak to peak output of 4000W, which allows the unit to provide an accurate representation of the bottom down to 1,500 feet. The XI 9 20 transducer features coverage angles of 20° and 60° @ -10db, so that you can adjust the coverage to suit depth and angling conditions for the best returns.
Use the built-in GPS unit to mark waypoints for structures or areas where you've had angling success and return to them at a later date. UniMap cartography covers the contiguous US coastline, inland lakes, and rivers at 30 meters per pixel resolution.
Pair the Ice Helix 7 with an optional open-water transducer and it can be used gimbal or dash-mounted in a boat, vehicle, snowmobile, or ATV.
