TM-265LH CHIRP Transom Mount


We know that specific frequencies excel at detecting certain species of fish: Bluefin Tuna—60 kHz, squid—133 kHz, and cod—175 kHz. The TM265LH transducer includes all these frequencies plus every other frequency in the high and low bandwidths. This powerhouse delivers excellent resolution, bottom discrimination, and bait and game-fish separation at all depths.


    Transom Mount Chirp Transducers

    Unlock the true potential of your fishfinder with the superior quality and performance of an AIRMAR Chirp-ready transducer.

    The Benefits of AIRMAR’s Chirp-ready Transducers 

    • One broadband transducer covers up to 117 kHz of bandwidth – greater opportunities to detect fish in the water column
    • Superior resolution – precise separation between baitfish and gamefish represented on the display with crisp images
    • Enhanced bottom fishing – resolve targets close to the bottom or near structure/wrecks
    • Amazing detail – recognise haloclines and thermoclines
    • Improved signal to noise ratio – find fish and track bottom at high boat speeds

    Benefits of Transom Mount Transducers

    Transom models are best suited for small and trailered vessels where a thru-hull installation is not practical. Perfect for freshwater boat styles and centre consoles. Simple to install and ideal for small trailered vessels where a thru-hull may interfere with loading.

    • Simple installation on transom of the boat
    • Great performance at boat speeds below 30 knots
    • Easy maintenance and low-cost replacement
