Fish Hawk Lithium Ultra System
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 BluetoothĀ® wirelessĀ 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.Ā Ā Ā Ā
The new, maintenance-free probe is 40% smaller than its predecessor and providesĀ more than 50-hours of fishing time on a single full charge.Ā Fish Hawk's Lithium Series incorporates four decades of experience with the lithium power anglers expect in modern electronics.
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 canāt get this information from traditional fishing electronics.
