Product Overview

The Fish Hawk TD reveals water temperature at depth. Temperature and water pressure sensors sample multiple times per second for unmatched accuracy. The TD has two modes of operation.

The BY TEMP mode provides a temperature profile of the entire water column at 5-foot intervals. Attach the TD to a fishing line and lower it to the bottom. Retrieve the TD to see the water temperature every 5-feet.

The BY DEPTH mode records maximum depth to the nearest foot. Use it to check the running depth of lures, divers, and weighted lines. Make your own dive charts by allowing the TD to slide to the end of your trolled lined.

    Works as Advertised

    I tried it out to get a temp profile for local reservoir. It worked great and the depth matched my sonar exactly on the bottom location.

    This is a time saver and works great, I really like the feature of lowering the unit while Trolling. Great product for the price.

    Water Testing

    We used the Fish Hawk TD the other day. Wow, does that streamline the process!

    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.
