The Fish Hawk Lithium Ultra Probe and Fish Hawk Lithium Ultra Probe with Charger are devices that transmit speed and temperature readings from underwater, as well as the true depth of your downrigger using water pressure. The Ultra is the latest top-of-the-line model from Fish Hawk Electronics, and it is compatible with its predecessor, the X4D Bluetooth.

The Fish Hawk Electronics Lithium Series incorporates four decades of experience with the lithium power that 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. Fish Hawk Electronics systems provide speed and temperature data at depth, making trolling more efficient. Salmon and trout are sensitive to water temperature, and knowing where it's favorable helps to eliminate nonproductive water and catch more fish. Underwater currents affect lures, causing them to behave unnaturally and disrupt the trolling speeds of your lure. Fish Hawk Electronics systems measure speed at depth, helping to maintain consistent down speeds so you can stay on the fish.

• Compatible with Fish Hawk X4D Bluetooth
• Transmits speed and water temperature at depth and true depth
• Lithium Series Probe provides 50+ hours of fishing from a single charge
• Probe fully charges in 2-4 hours, partially charges in 20 minutes
• 5,000+ lifetime probe charges
• Water-activated probe extends battery life
• A smaller profile cuts through water and minimizes blowback
• Works on any downrigger
• The probe uses a 70kHz sonar signal to send data
• Probe with charger includes wireless charging pad and USB-C cable
