<h3>About Airmar Technology Corporation</h3><p><strong>Airmar Technology Corporation</strong> is a globally recognized pioneer in ultrasonic and acoustic sensing solutions, headquartered in Milford, New Hampshire. <a href="/11479-airmar">Airmar</a> has spent more than three decades pushing the boundaries of what ultrasonic technology can accomplish on the water, earning a reputation as the go-to supplier for marine transducers, intelligent weather instruments, and network connectivity hardware across recreational, commercial, scientific, and military sectors.</p><h3>A Legacy Built on Ultrasonic Innovation</h3><p>At its core, Airmar's expertise lies in turning sound waves into actionable data. The company is widely regarded as the primary supplier of ultrasonic transducers to manufacturers of marine electronics for recreational boating, sportfishing, and commercial fishing. From compact sensors suited to personal watercraft to large-scale transducer arrays deployed on oceanographic research vessels, Airmar products are engineered to perform reliably from the surface to full ocean depth. As part of the Amphenol Interconnect and Sensor Systems Division, Airmar continues to expand its reach while retaining its deep roots in marine innovation.</p><p>The brand's <a href="/200641-transducers-accessories-airmar-11479">transducers and accessories</a> represent the heart of its catalog. Airmar's CHIRP-capable transducers deliver broadband sonar coverage, enabling more detailed fish arches, precise depth readings, and superior bottom discrimination compared to traditional single-frequency units. Whether thru-hull, transom-mount, or in-hull, Airmar transducers are trusted by both OEM boat builders and individual boaters upgrading their electronics suites.</p><h3>WeatherStation Instruments &mdash; All-in-One Environmental Intelligence</h3><p>One of Airmar's most distinctive product lines is its WeatherStation family, which falls within its broader <a href="/200363-electronics-parts-accessories-airmar-11479">electronics parts and accessories</a> lineup. These compact, all-in-one instruments consolidate up to seven environmental sensors into a single rugged, UV-stabilized housing with no moving parts to wear out or foul. Using proprietary ultrasonic technology, they measure true and apparent wind speed and direction, temperature, humidity, dew point, wind chill, and barometric pressure &mdash; all from one mountable unit. Models like the 110WX, 220WX, and the newer 300WX series (featuring Bluetooth integration and expanded communication protocols) make them suitable for everything from marina weather monitoring to dynamic platforms aboard unmanned surface vehicles.</p><p>Broad protocol support across the WeatherStation family &mdash; including NMEA 0183, NMEA 2000&reg;, J1939, and CAN-based interfaces &mdash; ensures compatibility with virtually any modern marine electronics network. Airmar extended its standard product warranty from two to three years in 2025, underscoring its confidence in the long-term durability of its instruments.</p><h3>Connectivity: Cables, Adapters, and NMEA 2000 Networking</h3><p>A sensor is only as good as the network it feeds. Airmar addresses this reality with a comprehensive range of <a href="/200282-connection-kits-cable-adapters-airmar-11479">connection kits and cable adapters</a> purpose-built for its instruments. Dedicated WeatherStation cables are available in NMEA 0183, NMEA 2000, combined NMEA 0183/2000, and manufacturer-specific configurations, making integration straightforward regardless of the chart plotter or display aboard.</p><p>For boaters building or expanding a full onboard data network, Airmar's <a href="/200717-nmea-2000-interface-cables-and-connectors-airmar-11479">NMEA 2000 interface cables and connectors</a> provide a USA-manufactured, fully standards-compliant solution. Featuring zinc-alloy housings and gold-plated pins, these connectors are engineered to resist corrosion, vibration, and signal degradation in demanding marine environments. The product range covers all backbone components &mdash; drop cables, tee connectors, terminators, power tees, and field-attachable connectors &mdash; making Airmar a one-stop source for both sensing hardware and the network infrastructure needed to tie it all together.</p>

Product Details

The Airmar B75C-12-M-MM is a bronze thru-hull CHIRP transducer designed for serious anglers and fishing professionals who demand exceptional underwater clarity and target separation. This 600W transducer features a 12-degree tilted element, making it ideal for installation on deadrise hulls up to 25 feet in fiberglass or wood construction.

Medium CHIRP Technology:

Operating across a wide frequency range from 80 kHz to 130 kHz, this transducer delivers 50 kHz of total bandwidth with beamwidths ranging from 24° to 16°. CHIRP technology provides 5 to 10 times greater detail and resolution compared to traditional single-frequency transducers, allowing you to distinguish individual baitfish, game fish, and underwater structures with remarkable precision. The broadband coverage includes popular fishing frequencies of 88 kHz and 107 kHz, plus everything in between.

Key Features:

  • Medium CHIRP range: 80-130 kHz with 50 kHz total bandwidth
  • 600W power rating for deep water performance down to 3,000 meters (10,000 feet)
  • 12° tilted element for optimal performance on angled deadrise hulls
  • Integrated fast-response water temperature sensor
  • Durable bronze housing with excellent corrosion resistance
  • Exclusive Xducer ID® technology for automatic transducer recognition
  • Mix and Match cable system for compatibility with multiple chartplotter brands

Installation Requirements:

This transducer requires a separate Mix and Match cable (sold separately) to connect to your compatible fishfinder or chartplotter. Suitable for boats up to 8 meters (25 feet) with fiberglass or wood hulls. The 12° tilt angle accommodates hull deadrise angles for optimal sonar performance.

Note: This product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns.
