Fish Hawk Lithium Ultra System FH250

The Fish Hawk Lithium Ultra System is the new standard in trolling-specific electronics. The Ultra, our new flagship system, delivers speed and temperature data from both the surface and at depth. It also transmits the true depth of your downrigger using water pressure. Using Bluetooth technology, the Lithium Ultra System integrates with Cannon Optimum Downriggers and the Humminbird One-Boat Network, or the Fish Hawk mobile app. This allows access to Fish Hawk data from multiple displays on the boat.

Charging Ahead! The Fish Hawk Electronics Lithium Series incorporates four decades of experience with the lithium power anglers expect in modern electronics. The new, maintenance-free probe is 40% smaller than its predecessor and provides a weekend of fishing on a single charge.

Underwater currents make trolling speeds at depth unpredictable. Temperature throughout the water column can change dramatically. Fish Hawk Electronics delivers speed and temperature data at depth to make trolling more efficient and effective. You can’t get this information from traditional fishing electronics.
