Fish Hawk Lithium Ultra Probe – Speed, Temperature & True Depth

The Fish Hawk Lithium Ultra Probe delivers the most important trolling data right where it matters—at depth. By measuring speed, water temperature, and the actual depth of your downrigger (via water pressure), the Ultra takes the guesswork out of trolling. It’s also fully compatible with the Fish Hawk X4D, making it a smart upgrade for existing users.

Why Anglers Choose the Ultra

• Actual Speed at Depth – Surface speed doesn’t tell the whole story. Underwater currents can change lure performance dramatically. The Ultra shows your actual trolling speed where your lures are running.
• Find Productive Water – Water temperature can shift quickly throughout the water column. The Ultra identifies temperature breaks so you can target fish in their preferred zone.
• Built for Performance – At 40% smaller than its predecessor, the Ultra cuts through water cleanly, reducing blowback and improving accuracy.

Smarter Trolling, Better Results

Traditional electronics can’t tell you what’s happening at depth. The Fish Hawk Lithium Ultra Probe gives you the speed, temperature, and depth data you need to fish smarter, adapt faster, and consistently put more fish in the boat.
