Just clip TD Connect to your fishing rod and line with a weight, drop it to the bottom, reel it back up, and open the free TD Connect app. There are no buttons, menus, or setup; the device automatically turns on when it hits the water and records temperature and depth as it descends. As soon as it comes back out of the water, the full temperature and depth profile is sent wirelessly and instantly to your smartphone or tablet.
On the app, you will see exactly how temperature changes with depth and choose to view the profile in 1', 5', or 10' increments. Enter your target species’ preferred temperature range in Target Temp Mode, and the app highlights the precise depths where that band of water exists, so you can immediately target the real strike zone. Every drop is automatically saved in your personal logbook with date, time, and GPS location (no cell service required), and you can add your own notes or share data with partners via text or email.
