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.
Q: Will it interfere with my fish finder?
A: No. The probe operates on a unique sonar frequency and will not interfere with 200 kHz, CHIRP, or side imaging transducers mounted next to each other.
Q: Is the Ultra Probe compatible with older Fish Hawk models?
A: Yes. It works seamlessly with the Fish Hawk X4D system.
Q: How do I best care for the probe?
A: Avoid deep discharges and charge before storing. Storing it at moderate temperatures and performing monthly maintenance charges during the off-season will ensure many seasons of reliable performance.
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.
Used for first time 7/18-20/2025 on Lake Ontario. Fish Hawk Probe worked flawlessly. Very happy with the new design. Hope to have many years of service, Thank you for your customer service.
Customer Service is always very helpful, and go the extra mile to help solve any difficulties I may be having. They were very responsive via email and by phone. They really try hard.
Customer service guy was off the charts awesome!
It works awesome!!!! So nice to not have to worry about batteries or water getting into the probe. It is much smaller so there is minimal blow back. Refresh rate for information is much faster. Overall a HUGE upgrade from the previous probes. Highly recommend this product, plus they are a great company!!!
Seems to be better than the original. Long battery life will be better. And complete waterproof encasement is a huge plus.
Slow to change from the old probe (stubborn ole cap) but happy to have this updated version!! Definitely redesigned and improved performance that delivers its promises! less blowback and quicker info which helps pinpoint down breaks with accuracy! The most important electronic on boat besides vhf radio ? great job Fish Hawk! thanks for the support and years of great products … Captain Kurt Driscoll Stalker sport fishing Western Lake Ontario
Have not used it yet much smaller than the old unit charging system works well can’t wait to try it out
Worked very well. Especially liked the fact that it is completely sealed. No wires or batteries to contend with. Also, much less blow back.
Just purchased, it’s the first week of April can’t wait for marina to open to drop boat in slip. Added new Fish Hawk LITHIUM ULTRA PROBE with my X4D really like new profile and sensor placement on this probe. And 4 new CANNON OPTIMUM electric downriggers. Excited to have one boat network. It’s sure to be an awesome season!!
