This patented system allows you to monitor the speed of the  lure - not the speed of the boat. You know immediately if under water currents are  affecting the lure's action. You also monitor changes in temperature right where it's  happening, at the lure.

The Sub Troll 900 consists of only three  interacting parts. The display readout, the antenna, and the sending unit. The sending unit attaches to the downrigger cable and transmits a signal to the antenna mounted on the downrigger boom. From the antenna the signal is sent to the display through a cable. There  is no physical contact between the sending unit and the display readout. The readout may  be installed up to 25 feet from the downrigger.

The Sub Troll 900 is the only system available  that does not require transducers or grounding rods. Because the Sub Troll uses a radio  signal for the transmission of information, you eliminate bothersome problems associated  with sonar type systems. The 9-volt battery will last up to a full season and, no  interference with sonar or other electronics on the boat. But most important, a constant reading on the display, even in choppy lake conditions.

The  underwater sending unit automatically turns its transmitter off when removed from the water. This insures that the 9-volt battery will  remain ready for your next fishing trip. While trolling after dark, the Units Illuminating displays make easy work of controlling the speed and temperature. The Sub Troll display requires 12 volts to operate.
