Airmar

<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-MW-8G is a revolutionary 1kW CHIRP-ready thru-hull transducer featuring Medium Ultra-Wide (MW) Tilted Element technology. This advanced transducer operates on medium frequency (60-100 kHz) and delivers exceptional coverage with an ultra-wide beamwidth ranging from 57-73° port-starboard and 16° average fore-aft. Designed for anglers targeting pelagic species in the upper water column, the B175MW provides maximum coverage under the boat for superior mid-depth performance.

The innovative Tilted Element design features a ceramic element fixed at a 20° angle, allowing the transducer to be installed nearly flush with the hull. This tilted configuration corrects for hull deadrise and orients the element vertically to ensure maximum echo returns. The result is excellent fish-target separation and reliable depth tracking down to 400 meters (1,300 feet).

Key Features:

  • Medium frequency CHIRP technology: 60-100 kHz with 40 kHz total bandwidth
  • Ultra-wide beamwidth: 57-73° port/starboard by 16° average fore/aft
  • Fixed 20° tilted element optimized for 16-24° hull deadrise angles
  • 1 kW power rating with depth tracking to 400 m (1,300')
  • Integrated fast-response water temperature sensor
  • 8-pin connector compatible with Garmin fishfinders
  • Bronze housing suitable for stepped, planing, or displacement hulls
  • Low-profile thru-hull design for excellent resolution at speed
  • Exclusive Xducer ID technology for automatic configuration
  • Urethane acoustic window for optimal signal transmission

Technical Specifications:

  • Mounting style: Tilted element thru-hull
  • Installation hole size: 95 mm (3-3/4")
  • Hull compatibility: Fiberglass or wood
  • Maximum vessel length: Up to 11 m (36')
  • Cable length: 9-10 m (30-33')
  • Operating temperature range: -10° to 40°C (14° to 104°F)
  • Weight: 2.7 kg (6 lbs)
  • Material: Bronze construction
  • Country of origin: USA

This professional-grade transducer is ideal for serious anglers seeking superior mid-depth performance and can be paired with other Airmar models like the B275LHW to create a comprehensive frequency range from deep to shallow water applications.

Excellent product and service.
