Garmin TM265LM CHIRP Transom Mount Depth and Temperature Transducer Barewire
Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The Garmin TM265LM is a 1 kW plastic transom-mount CHIRP transducer that pairs a low band of 42 to 65 kHz with a medium band of 85 to 135 kHz. The low frequency reaches deep water while the medium band widens coverage and lifts target separation through the mid-range, making it a strong all-round offshore performer.
This bare-wire model reads to a maximum depth of 3,000 ft and mounts on transoms with a deadrise of 3 to 21 degrees on a 39 ft cable. It connects to the Garmin GSD 26 CHIRP sonar module via its terminal block and also reports water temperature.
The kit includes installation instructions; follow them carefully to avoid damaging your boat.
