Nice response from service request. I was surprised when my unit failed since I have friends with much older units. Overall I am happy with the product ( quite expensive) and the service response from Fish Hawk. I think it is a valuable tool on my boat fishing Lake Michigan.
unit works well. Reliability is in question. Service and support from Tanya Bocock is excellent.
My very old display finally gave out… This insulation was quick and easy plugged it in & a big improvement easy to read works great thank you!
I had the original Fish Hawk 840, which I wasn't impressed with. The battery life was very short (ran on 9V battery), and the signal was iffy below 50 feet in depth. I upgraded the probe last summer, and was impressed at the performance. The battery life improved (4 AA's) significantly as well as a much better signal. I added the new X4 display this spring, and it is well lit, and the displayed numbers are big and easy to read. Very happy with the new X4 display.
