Garmin GT15M-TM is the ideal transom-mount CHIRP transducer for anglers who want a pure fishfinder solution with excellent bottom definition, clear fish arches, and good target separation — even at great depths.
With a transmit power of 600 W and CHIRP in the mid-band frequency range of 85–165 kHz, it delivers stable and clear sonar images for serious fishing up to approx. 600 meters / 1,900 ft in freshwater.
The GT15M-TM measures both depth and temperature and comes with robust mounting hardware for transom installation. The wide transom mounting angle makes it suitable for a large variety of boat types, making it a popular choice for all-round use.
