The Fish Hawk Lithium Pro System is the latest generation of our most popular system, the Fish Hawk X4. The Lithium Pro delivers speed and temperature information from the depths and at the surface. This system works with any downrigger, making it a great choice for all serious trolling anglers, no matter 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.
