Fish Hawk Lithium Ultra System – Advanced Trolling Speed & Temperature Electronics

The Fish Hawk Lithium Ultra System is our flagship trolling electronics package, engineered for serious anglers who demand accurate, real-time data at depth. Featuring the all-new Double Wide Transducer and next-generation Lithium Series Probe, this system delivers unmatched performance, reliability, and convenience on the water.

Real-Time Speed, Depth & Temperature at Depth

Unlike traditional fishing electronics that only read surface conditions, the Fish Hawk Lithium Ultra System transmits actual trolling speed, water temperature, and depth readings from your downrigger. By using water pressure to measure actual depth, you get the precise data needed to put your lures in the strike zone.

Seamless Wireless Integration

Built with Bluetooth® wireless technology, the Lithium Ultra System connects with:

• Cannon Optimum Downriggers
• Humminbird One-Boat Network®
• Fish Hawk Mobile App

This integration lets you view and log Fish Hawk data from multiple displays or mobile devices anywhere on your boat.

Lithium Series Probe – Smaller, Smarter, Longer-Lasting

The Lithium Ultra Probe is 40% smaller than previous models and powered by a long-life lithium battery. Benefits include:

• 40 hours of run time on a single charge
• Fast charging: full charge in 2–4 hours, partial charge in just 20 minutes
• 5,000+ lifetime charges
• Water-activated design – turns on only when submerged
• Compact profile reduces blowback for more accurate depth readings

Double Wide Transducer – Twice the Coverage

The Double Wide Transducer is engineered for superior performance in deep water, strong currents, and higher trolling speeds. Its expanded cone angle doubles signal reception compared to legacy Fish Hawk transducers, virtually eliminating signal loss from blowback.

Key design features:

• Reliable signal in extreme conditions
• Compact, easy-to-install mount
• 3D-printed transom bracket for maximum strength and perfect alignment

Easy-to-Read Display
