    First time out with this small pocket sized unit , I was a little doubtful in its value. I hooked it up to my rigger and sent it to the bottom. Pulled it back up and hit the view button. Wow! What a sweet little unit. Did exactly what was advertised. It clearly showed a temperature break at around 95 feet in 230fow. This told me to run my baits deep. Result was a box full of king salmon fillets. Home run on a more affordable unit that anyone can benefit from. Temperature is crucial when targeting cold water species, and this unit is a must have.

    I love my Fishawk TD

    I use it several times per morning to determine temperature breaks when fishing salmon on Lake Michigan. On inland lakes I use it to find thermocline/oxycline levels. It is a great little device. Pretty durable too. Just take care of it like it says in the instructions. It’s really necessary on the big lake.

    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.

    Fish Hawk TD

    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

    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.
