The ST-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 ST-900 is the only system available that does not require transducers or grounding rods. Because the ST-900 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 (see note below). But most important, a constant reading on the display, even in choppy lake conditions.
The ST-900 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 ST-900 Illuminating displays make easy work of controlling the speed and temperature. The ST-900 display requires 12 volts to operate.
