Running More Than One Garmin® Transducer at a Time

While it is not recommended that more than one transducer be run simultaneously, there can be multiple transducers installed on a boat.

If two transducers are transmitting at or close to the same frequency and the signals cross, interference may appear on the display of the  chartplotter. For best results, two transducers need to have at least a 50 kHz difference in their frequencies to not cause interference.

Some chartplotters will share their built-in sonar with a compatible chartplotter. This allows for a single transducer to be shared through the Garmin® Marine Network. See Marine Network Sharing Compatibility to check for compatibility of specific chartplotters.
