Airmar TM185M – Single Band, Medium Frequency, CHIRP Transom Mount Transducer, No Connector
These are suitable for shallow to medium depths and work great with any of the Garmin GPSMAP 1kW CHIRP units.
This is a great 1kW option with medium CHIRP capability. Covers shallow to deep operation. We have tested these and still had fish pick up at ~400m. Complete with transom mount bracket for trailer boats. As it is bare wires will require Garmin adaptor box to fit to the 8 pin transducer connector.
You can run one of these on the Garmin GPSMAP series coupled with a GT51M-TM transducer and have both connected at the same time, giving you SideVu and DownVu functionality as well as shallow to deep water CHIRP traditional sonar – the fish don’t have a chance.
