<h3>Airmar Technology Corporation: Leaders in Marine Sensing</h3><p><strong>Airmar Technology Corporation</strong> has been at the forefront of acoustic and ultrasonic sensing since its founding in 1982 in Milford, New Hampshire. Over more than four decades, the company has grown from a single-product transducer manufacturer into the world&apos;s leading designer and maker of high-performance marine sensing technology — earning a reputation for precision, durability, and innovation across recreational, commercial, scientific, and military applications.</p><p>At the core of Airmar&apos;s identity is a deep expertise in ultrasonic technology. As one of the company&apos;s directors famously put it, Airmar doesn&apos;t build marine electronics — it builds high-end &quot;speakers.&quot; That philosophy has made Airmar the trusted OEM partner behind the transducer technology found inside some of the biggest names in marine electronics. From sport fishing to offshore surveying, Airmar products are engineered to deliver reliable, high-resolution data whether you&apos;re chasing gamefish in shallow freshwater or conducting hydrographic surveys at depth.</p><h3>Marine Transducers for Every Application</h3><p>Airmar&apos;s lineup of marine transducers spans everything from entry-level transom-mount sensors to professional-grade CHIRP thru-hull transducers capable of reading extraordinary depths. Their CHIRP-ready transducers operate across low, medium, high, and high-wide frequency bands, providing anglers and mariners with exceptional target separation, bottom detail, and depth performance. Crucially, Airmar&apos;s &quot;Mix &amp; Match&quot; cable system means a single transducer body can be paired with brand-specific adapter cables — making it easy to upgrade your electronics without swapping out the transducer itself.</p><p>Airmar transducers are engineered to work seamlessly with leading marine electronics platforms. Their <a href="/11479-airmar-raymarine-transducers-accessories-202422">Raymarine-compatible transducers and accessories</a> are a popular choice for Axiom and other Raymarine multifunction display users who want industry-leading sonar performance. Likewise, Airmar&apos;s <a href="/11479-airmar-humminbird-transducers-cables-accessories-202118">Humminbird-compatible transducers, cables, and accessories</a> — including dedicated 9-pin and 14-pin connector variants — integrate directly with Helix, SOLIX, and APEX fish finders for plug-and-play CHIRP capability.</p><h3>WeatherStation Instruments</h3><p>Beyond transducers, Airmar is renowned for its WeatherStation® instruments — all-in-one ultrasonic weather sensors that consolidate multiple measurement capabilities into a single compact, rugged housing. Using proprietary ultrasonic technology with no moving parts, these instruments measure wind speed and direction, temperature, humidity, barometric pressure, and rainfall simultaneously. Because they rely on ultrasound rather than mechanical anemometers, they are immune to bearing wear and unaffected by salt, dirt, and marine fouling — making them exceptionally reliable in harsh environments.</p><p>WeatherStation instruments are deployed worldwide on fixed marine platforms, unmanned surface vehicles (USVs), research vessels, and land-based weather monitoring stations. They are trusted by organizations ranging from recreational boaters to national oceanographic centers.</p><h3>Quality and Warranty</h3><p>Airmar&apos;s commitment to quality is reflected in its manufacturing process — largely hands-on and craftsmanship-driven — and in its warranty program. As of 2025, Airmar extended its standard product warranty to three years across its full lineup, including transducers and sensors. Installers who are Airmar Certified Installers (ACIs) can offer customers an exclusive extended warranty on qualifying transducers, reinforcing the brand&apos;s long-term support philosophy.</p>

Product Details

The Airmar B175C-20-HW-8G is a high-performance bronze thru-hull transducer engineered to deliver exceptional sonar imaging and fish-finding capabilities for Garmin chartplotters and fishfinders. This wide-beam, CHIRP-ready transducer operates across a high-frequency range of 150 to 250 kHz with an impressive 100 kHz of total bandwidth from a single installation, providing superior shallow-water performance, detailed bottom imaging, and excellent fish-target separation.

Key Features:

  • Wide-beam CHIRP technology with constant 25° beamwidth across entire frequency range for twice the coverage compared to narrow-beam transducers
  • High-frequency band (150-250 kHz) delivers superior resolution and detailed views of the water column
  • 20° tilted element design corrects for hull deadrise, ensuring maximum echo returns when installed flush to the hull
  • 1 kW power output provides strong signal transmission for depths up to 152 meters (500 feet)
  • Integrated fast-response water temperature sensor for accurate environmental monitoring
  • Durable bronze housing designed for fiberglass and wood hulls (suitable for vessels 25 feet and above)
  • Garmin-specific 8-pin connector with Xducer ID technology for plug-and-play compatibility
  • Creates crisp, clear fish arches and larger return images on display compared to narrow-beam alternatives

The tilted element design allows the transducer to be installed almost flush with the hull while the 20° tilt angle orients the ceramic element horizontally, compensating for hull deadrise and maximizing sonar performance. Ideal for both inshore and pelagic fishing applications where resolution and maximum bottom coverage are essential. The B175HW series represents Airmar's advanced wide-beam CHIRP technology, offering professional-grade performance for serious anglers and charter captains.
