These transducers have only been out for a couple of years but have made a huge impact. They have a very similar transducer to the low frequency side of a TM265, but there are 3 main reasons why you would want to go thru hull. 

* Move the transducer away from turbulence – transducers don’t like turbulence and the transom is the most turbulent part of a boat.

* Move the transducer away from the source of electrical and mechanical(vibration) noise – which is normally the outboard / sternleg

* Encapsulated in metal tends to work better than the plastic encapsulated transducers

In the box is actually a plastic isolating ring too, so very suitable for aluminium boats. When installed, they’re only about 10mm proud of the hull, so it is normally quite possible to find a spot which doesn’t interfer with the existing trailer!

This particular one is 20 degree tilt which we find best for most NZ built boats, and it comes with a Garmin 8 pin transducer plug molded on. If using an FCV295 or BSM3 you can just cut the plug off and wire the bare ends


  • Low-Frequency CHIRP (L)
  • Chirps from 40 kHz to 60 kHz -> 32° to 21° beamwidth
  • 20 kHz of total bandwidth from one transducer
  • Covers popular fishing frequency of 50 kHz plus can be set to any other frequency within the bandwidth

Whether you’re a commercial fisherman, charter skipper, or tournament angler, CHIRP transducers will enable you to detect the bottom  down to 3,000m (10,000’) with 5 to 10 times greater detail and resolution so precise it’s possible to distinguish between individual baitfish, game fish, and underwater structures. One transducer delivers up to 80 kHz of total bandwidth in just one installation, saving customers time and money.

This transducer is designed for smaller boats up to 36 feet (11 m).
