The TM275LHW transom-mount CHIRP transducer combines depth sensing with a fast‑response water‑temperature sensor, designed for anglers who want broad coverage and reliable readings from a single unit.
-
CHIRP coverage and beamwidth: Low–CHIRP 42 kHz–65 kHz with beamwidth 25°–16°; High–CHIRP 150 kHz–250 kHz with constant beamwidth 25°. Broad bandwidth totals 123 kHz from a single transducer, and the design supports wide-band coverage that includes popular 50 kHz and 200 kHz frequencies.
-
Transom-mount design: TM275-LHW transducer with no connector; includes mount brackets and hardware.
-
Integrated sensors: Depth sensing plus a fast‑response water-temperature sensor for on‑water data.
-
Under-boat coverage: Wide beam transducer design provides twice the coverage under the boat compared to current high-frequency CHIRP transducers.
-
Hull compatibility: Suitable for hulls with a deadrise up to 28°.
-
Acoustic window: Urethane window protects performance in marine conditions.

In the box: TM-275 LHW Transom Mount Bracket and Hardware; 3 × 3° shims.
With a steady 25° beam across high frequencies and broad coverage over the water column, this transducer helps you spot structure, schools, and fish more reliably. The built-in temperature sensor adds valuable on‑water data for fishing decisions and environmental awareness. The included mounting hardware and shims simplify installation on many boats, and the urethane window protects performance in marine conditions. Its hull compatibility up to 28° deadrise makes it a versatile choice for CHIRP‑enabled sonar setups.
