In addition to gauging speed and temperature, the new Cannon IntelliTroll tracks the depth at your lure - delivering the most comprehensive, accurate readings of the water below. And with a blow-back reducing, hydrodynamic design, you get the clearest, most consistent controlled-depth fishing possible. IntelliTroll is ready to fish, right out of the box. An easy-on, easy-off clamping mechanism eliminates the need to cut wires for attachment, while creating a more stable electrical connection and a stronger mechanical connection. An integrated wet switch automatically activates IntelliTroll when it hits the water, and data is delivered on a large, clear LCD screen.
