Garmin TM275LH-W CHIRP

This is the new wide beam chirp 1Kw transom transducer. This gives a constant 25deg coverage twice that of the TM265LH.

It makes more sense as you want a wider beam width in shallow water targetting snapper and terakahi but want a narrower beam width in deeper water when targetting bluenose and puka

Fits CHIRP sounder modules which take bare wires – eg Garmin GSD26 or Furuno DFF1uHD. If you want to use one with the new GPSMAP 7400 series, then you will need a bare wire adapter. An 8 pin adapter will give you either high or low frequency, where a 12 pin adapter will give you access to both frequencies.


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° beam width, 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 beambwidth 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.
