Designed for ice fishing, it provides clear bottom definition under the ice as well as crisp, clear and wide fish arches with excellent target separation. The wide beam width up to 24 beam angle provides a large coverage area in the water. Beam width can be adjusted, allowing fishermen to dynamically change the beam from 24 to 16.

Its shape and beamwidths have been optimized for ice fishing and feature a silicon-coated cable that remains flexible in harsh winter conditions.Mark Spots with high-sensitivity GPS: Unlike regular fishfinders, Striker fishfinders have built-in, high-sensitivity non-mapping GPS to locate your current position quickly and precisely, then maintain your GPS location anywhere you go on the lake. More importantly, they allow you to mark spots where the fish are biting so you can return to them again in the future. You also can mark docks, boat ramps and other locations on the lake. Just follow the path created on your screen to return to them whenever you wish.Fish vertically with built-in flasher: Striker provides you with both a fishfinder and a traditional, old-school flasher all in one unit. Anytime you are stationary fishing, such as ice fishing or jigging for crappie, the built-in flasher will show you the bottom, whether it is solid or muddy, your jig or weighted bait, and the depth of fish as they swim into the sonar beam. You can even watch how high your jig is being lifted and dropped and whether fish move toward or away from it.Take your fishfinder anywhere: The included portable kit protects and carries your Striker 5 fishfinder with GPS, so its perfect for ice fishing or fishing from a dock. It includes a sealed, rechargeable battery with charger, built-in transducer
