Minn Kota offers some trolling motors with a transducer built in. These transducers operate at 83kHz and 200kHz. A few select Garmin devices are capable of utilizing both of these frequencies. To connect these transducers to Garmin devices, and adapter cable will be required.
If the Garmin device requires a 4 pin transducer, MKR-US2-12 part number should be used.
If the Garmin device requires a 6 pin transducer, MKR-US2-1 part number should be used.
If the Garmin device requires an 8 pin transducer, MKR-US2-14 part number should be used.
Here is a link to the Minn Kota webpage that sells these adapters.
List of devices that can utilize the 83kHz and 200kHz frequencies from the Minn Kota transducers:
Devices not listed above can use the 200kHz frequency, but will not be able to utilize the 83kHz frequency. The appropriate adapter will still be required.
