Airmar Transducers & Accessories

Airmar Transducers & Accessories: Precision Underwater Sensing

Airmar Technology Corporation has been the benchmark for marine transducer engineering since its founding in 1982. What began as a single transom-mounted transducer has evolved into one of the most comprehensive transducer and accessories lineups in the marine industry — trusted by recreational anglers, competitive fishermen, commercial mariners, and oceanographic researchers alike. Founded in Milford, New Hampshire by engineer Steve Boucher, the company's first product was a transom-mounted transducer that worked with a variety of fish finders — a philosophy of universal compatibility that still defines the brand today.

CHIRP Technology and Broadband Performance

Airmar's CHIRP-ready transducers make the market's best fishfinders and sounders even better — for decades, the Airmar brand has been the top choice of boaters and anglers around the globe, long known for technological advantage and the highest quality. Unlike traditional single-frequency sonar, CHIRP transducers sweep through a continuous range of frequencies, delivering dramatically improved target separation and depth resolution. Airmar offers a wide range of options including CHIRP, broadband, and multi-frequency transducers , covering everything from shallow-water sport fishing to deep-sea survey work.

New 1 kW models feature Airmar's revolutionary concave ceramic array, delivering an exceptionally wide beamwidth of up to 73° port/starboard in the medium frequency range (60–100 kHz). This ultra-wide beam allows for significantly greater underwater coverage than traditional transducers, while the high frequency range (150–250 kHz) provides a 25° beamwidth, ideal for detecting smaller targets with high-resolution detail.

Smart Sensors and NMEA 2000 Integration

The DST820 Smart™ Multisensor is Airmar's next-generation multisensor, delivering industry-leading speed through water accuracy plus integrated depth, water temperature, and pitch and roll data to NMEA 2000® networks, or wirelessly to Airmar's CAST™ app. Advanced embedded microelectronics process signals within the sensor for display on any NMEA 2000® compatible device , making these sensors straightforward to integrate into modern chart plotters and multifunction displays.

Mix & Match Cables and Accessories

One of Airmar's most practical innovations for installers and upgraders is their Mix & Match cable system. Mix and Match 1 kW transducers are made as a common base transducer with a short (2m) cable attach ment point, allowing boaters to pair a single transducer body with brand-specific connector cables. Airmar's patented Transducer ID™ makes connecting to popular brands possible, including Garmin, Simrad, Raymarine, Furuno, Lowrance, Humminbird, and more. This means one quality transducer can move with you across upgrades and different helm electronics.

Mounting Options and Hull Compatibility

Airmar transducers are available in popular transom-mount, in-hull, and through-hull applications , ensuring there is a solution for virtually any hull type or installation scenario. From small jet-ski sensors to large steel-tank transducers, Airmar's depth, speed, and temperature sensors are among the most responsive in the market. Accessories such as hull nut wrenches and mounting hardware round out the category, giving installers everything needed for a clean, professional setup.

Whether you're upgrading a weekend fishing boat or outfitting a serious bluewater vessel, Airmar's transducers and accessories represent the gold standard in underwater acoustic sensing.
