    Water Testing

    Posted by Barb on 16th Dec 2012

    We used the Fish Hawk TD the other day. Wow, does that streamline the process! Barb – Hungry Jack Lake Water Monitor – Cook County, MN I attached a photo of Cook SWCD staff using the Fish Hawk during water monitoring. It works great and aids in the accuracy of gathering data.

    Good Product!

    Posted by Randy Carlson on 3rd Sep 2012

    How could Lake Michigan be 69f down to 155ft? I thought the probe was bad but after checking with the Charters the thermal cline started at 170ft! The next day it rose to 140ft. We caught several fish both days, Thanks Fishhawk for a great product!

    T/D is a "Must Have" for fishing

    Posted by Francis on 2nd Sep 2012

    The first time I tried the T/D was on the south end of Lake Michigan. We found the temperature to be 75 degrees down to 40 ft. It dropped to 55 degrees between 40 and 45 feet. The fish finder showed fish between 37 and 40 feet and no fish shallower than 35 ft or deeper than 42 ft. We were in search of perch and did catch some small ones before the sun set on us.

    It works as advertised

    Easy to use - either on a line or a rigger. I put an extra line on the eye as a safety and used a snap swivel to hook on to my rigger weight in case the attachment came loose. I'd haste to lose it!!

    Fish Hawk TD

    Outstanding operation, easy to operate and read. The only concern is loss prevention, the line fastener is easy enough to use but not to sure how durable it is.

    Hi I'm from Canada, near Montreal Province of Quebec. I fish the St-Laurent River and many lakes for Lake trout in the north region of the province. I ordered the Fish Hawk TD and the transaction was fast and the delivery was beyond my expectation. I tried it yesterday for the first time and it’s a great tool for fisherman like me who is using all the technology available to increase your chance to catch fish. Tanks again to Fish Hawk

    Fishing Club Endorsement

    Posted by Bob B. - Twin Lakes Walleye Club on 22nd Feb 2012

    Just a short note to express our satisfaction with the Fish Hawk TD temperature probe. Water temperature is extremely important in understanding fish behavior during the spring, summer and fall fishing season. We routinely measure the water temperature of Bull Shoals lake and publish the results to our Club members. Since we started using the FishHawk device our temperature measurement process has decreased from approximately 20 minutes (old method) to less than 1 minute of effort. Additionally our data is substantially more accurate. Our members appreciate the data and we appreciate the accuracy and convenience.
