Fish Hawk Electronics
Lower the Fish Hawk TD to record water temperature every 5-feet from the surface to the bottom. Locate the depth of fish by finding their preferred water temperature within the water column.
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.
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.
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.
It does everything it claims to do. Great
Yes, I was apprehensive, but... I read the instructions and followed them. Easy operation and was able to determine temperature down to 55'. Now my only concern is that my fishing line might break.
Works as advertised; short, easy instructions. Makes finding the productive water column a snap. No more guessing where the thermocline is located. Temperature at depth helps identify different species based on preferred temps. Great product.
