Product Overview

Airmar TM275C-LHW Transom Mount Low/High Wide CHIRP Transducer with Navico 7-Pin & Y Mix-N-Match Cable

Model: TM275C-LHW-BL2
  • Depth & fast-response water-temperature sensor
  • Low - CHIRPS from 42 kHz to 65 kHz - 25° to 16° beamwidth
  • High - CHIRPS from 150 kHz to 250 kHz - 25° constant beamwidth
  • 123 kHz of total bandwidth from one transducer
  • Covers popular fishing frequencies of 50 and 200 kHz plus everything else in the bandwidth

Get more coverage under the boat with Airmar's new wide beam Chirp product line. Offering a high frequency range of 150-250 kHz and a constant 25° Beamwidth, these transducers are truly broadband at its best. In addition to improving the performance of Chirp-ready echosounders, anglers using the new wide beam transducers will achieve twice the coverage under the boat compared to our current high frequency Chirp transducers.

A unique property of the new high frequency transducers is that the Beamwidth is a constant 25° angle across the entire frequency band. Now, in addition to providing vast bottom coverage and precise fish detection in the upper water column that can sometimes go unseen with our narrow beam transducers, Airmar's new wide beam format also creates crisper and larger return images on the display. We've got you covered.

Expert Overview

The Airmar TM275C-LHW Transducer is a transom-mount solution designed for marine applications, providing both depth and fast-response water temperature sensing. This unit utilizes CHIRP technology across two frequency ranges: a low band from 42 kHz to 65 kHz with a 25� to 16� beamwidth, and a high band from 150 kHz to 250 kHz with a constant 25� beamwidth. It offers 123 kHz of total bandwidth, encompassing common fishing frequencies like 50 kHz and 200 kHz, alongside other frequencies within its operational range. The wide beam design aims to increase coverage under the vessel and enhance target detection in the upper water column. This transducer is suitable for vessels with a hull deadrise of up to 28� and connects via a Navico 7-Pin & Y Mix-N-Match Cable. The part number for this model is TM275C-LHW-BL2.
