Engineered to be a powerful complement to live sonar or standard fishfinders, the Fish Hawk TD Connect Water Temperature and Depth Sensor provides a quick way to measure and record water temperatures throughout the entire water column from top to bottom. To use the TD Connect, simply attach its top end to your fishing line with one of the included snaps, and clip a weight to the bottom (1–3 ounces works well) with the other snap. Next, let the unit drop all the way to the bottom, then reel it back in. With no buttons, menus, or setup, the TD Connect turns itself on the instant it hits the water and records samples at a blazing fast 20 times per second, automatically sending data to your phone or tablet via Bluetooth when it exits the water at the end of the retrieve. Complete temperature and depth profiles are easily viewed with the free iOS and Android app, which also supports the use of multiple TD Connect units.

Additional features include a Target Temp Mode that visually highlights the best strike zones, an automatic logbook with date, time, and GPS, and a rechargeable internal lithium-polymer battery providing days of use between charges. Letting you instantly locate the best temperature band for targeting your preferred species, the Fish Hawk TD Connect Water Temperature and Depth Sensor is perfect for casting, trolling, or bait fishing in fresh and saltwater.
