    Great product.

    Great product. Works exactly as described. For us weekend warriors this is a very functional alternative to the $600-800 boat mounted unit and does the job.

    Will be using it soon in MN, to find where the Lake Trout are... Tested it in my pool, worked as advertised, was accurate for temperature and depth. Being a guy, not reading instructions, and can't see well, I almost ran a line through the thermister window, thinking the thermister was a molding defect. It could get damaged if someone isn't aware.

    Fine little device

    Posted by Tony Thorpe on 30th Mar 2021

    I coordinate a statewide group of volunteer lake water quality monitors. Many of our volunteers use these to track the depth and timing of lake stratification (or where and when the thermocline develops). They are easy to use and accurate enough for our purposes when compared to a YSI EXO3 (a fancy and expensive science doodad). I only wish the battery life were longer so we didn't have to replace the entire unit every 5 years, and would love if it could record in half-meter increments.

    FishHawk works like a charm!

    Posted by Robert Klamt on 9th Jan 2021

    This little unit does exactly as advertised. I used to work for the water quality board and did lake surveys, so was looking for an inexpensive way to get a temperature profile to help with fishing. This does the trick. One thing to be wary of--the instructions say not to let it get below freezing. I did with my first one (left it in the truck overnight), and it died.

    This device works as advertised. Very useful for finding your target fish species favorite temperature depth.

    I used my Fish Hawk TD today for the first time. Found the sweet spot right away and caught rainbows and browns. This is a great tool.

    Priceless tool

    Posted by D on 20th Jun 2019

    This instrument has singlehandedly helped me to catch a heck of a lot more salmon. I drop this down and find the magical 50 degree mark and begin trolling above and below this temp. This is an invaluable tool that helps you to reduce a 70 mile X 30 mile lake (Michigan) to a much smaller water by zeroing in your fishing around the temp's. BRAVO FishHawk.
