Moor Sub-Troll 900The 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. But most important, a constant reading on the display, even in choppy lake conditions. **Please allow 5 to 10 days for delivery** Moor Sub Troll 900 Price: $ 409.99 |
