Airmar

In 1982, AIRMAR brought its first product to market, a transom-mounted transducer. Two years later, the company patented the TRIDUCER® multisensor which revolutionized marine-sensor technology. From that modest beginning, Airmar has grown steadily to become the world-recognized leader in marine-sensing technology.

Airmar supply high performance transdcuers for all the major brands including Garmin, Lowrance, Raymarine, Simrad, howerver due to most manufacturers having unique plugs, they are rarely interchangeable.

New in 2011 is the Broadband Chirp Transducer that continuously operates 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 bottomand 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.

Depending on the model, these transducers contain a low-frequency ceramic array capable of running at either 28 to 60 kHz or 42 to 65 kHz. To complement the deep-water detection, either a high-frequency or medium-frequency broadband ceramic is also included. The high-frequency ceramics operate in the 130 to 210 kHz band.

The medium-frequency ceramics cover the 85 to 135 kHz band, which has historically beenused in commercial fishing, especially 88 and 107 kHz—due to certain fish species being better detected at these frequencies. This band has rarely been used in the sport fishing market, until now. Medium-frequency benefits include the ability to sound deeper than the high-frequency, along with better target resolution than the low-frequency. All low and high-frequency broadband transducers will carry an “LH” suffix after the model name while the low and medium-frequency transducers carry an “LM” suffix after the model name.
