Airmar TM265 CHIRP Fishfinder Transducer TM265C-LH

The TM265C-LH CHIRP transom-mount transducer has 8 internal, broadband ceramic elements. The low-frequency can be chirped from 42 to 65 kHz while the high-frequency chirps from 130 to 210 kHz. Beamwidths range from 16° to 25° on the low-frequency band and 6° to 10°on the high-frequency band. Also included is a high-precision water-temperature sensor for accurate sea-surface temperature readings.

Traditional transducers only operate at specific frequencies, most commonly 50 and 200 kHz. This is not ideal as various fish species, bottom compositions, and environmental noise present themselves differently on a sounder screen at different frequencies. With traditional fish finding, a target could be missed if the 50 kHz or 200 kHz were not able to detect it, and flow noise can easily overcome the sounders ability to show targets or even track the bottom. Over the past few years, Airmar has been developing a new transducer technology that is revolutionizing fish finding as we all know it. The result is a complete line of CHIRP Broadband transducers that operate equally well within a wide range of frequencies with an unprecedented level of performance and efficiency. It is now possible to detect targets at far greater depths and track bottom at much higher speeds than previously possible. Fish targets can literally be "pulled" out of the noise that would have overcome earlier technology sounders.

These revolutionary transducers continuously operate across a range of frequencies, rather than at the traditional dedicated frequencies of 50 kHz or 200 kHz. When transmitting at dedicated frequencies, targets that are smaller than the 50 kHz or 200 kHz sound wave may be undetected and therefore not shown on the fishfinder display. With CHIRP, the transmitted signal covers a wide band of frequencies, providing significant improvements in the ability to detect all targets in the water column. More bottom and water column area is covered as the beamwidth constantly changes from narrow to wide while the transducer is "chirped" across the specified band. It is proven that some fish species return better signals at specific frequencies, which makes CHIRP systems the optimal choice for fishfinding. Additional benefits include 25 to 50 times more energy on targets, enhanced detail and resolution, precise location (within inches) of fish in the water column or tight to the seabed, no noise interference, and extreme deep-water sounding below 10,000 ft.

CHIRP transducers are for use with sounders and fishfinders that have been designed specifically to control them. These include the Garmin GSD-26 and the Simrad BSM-2.

CHIRP transducers can also be used with Furuno sounders and fishfinders that have selectable frequencies, including the FCV-295, BBFF3 and DFF3 models. The increased efficiency and low Q of CHIRP Broadband transducers allows these traditional fish finders to more easily detect closely spaced targets and offers increased structure and bottom detail now, while paving the way for a future upgrade to CHIRP enabled electronics in the future.
