<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-12F is a high-performance 1 kW CHIRP thru-hull transducer designed for serious anglers targeting pelagic species in the upper to mid-water column. This medium-frequency transducer operates from 60-100 kHz with an exceptional ultra-wide beamwidth of 57-73° port-starboard and 16° average fore-aft, delivering maximum coverage beneath your vessel for superior fish detection and target separation.

The B175MW features Airmar's popular tilted element design with a ceramic element fixed at a 20° angle, ideal for hulls with 16° to 24° deadrise. The low-profile bronze housing installs nearly flush with the hull while the tilted element corrects for hull angle, ensuring the transducer orients vertically for optimal echo returns and excellent resolution even at speed.

Key Features:

  • Medium frequency CHIRP operation: 60-100 kHz with 40 kHz total bandwidth
  • Ultra-wide beamwidth: 57° to 73° port/starboard × 16° average fore/aft
  • Fixed 20° tilted element for 16° to 24° hull deadrise angles
  • 1 kW power rating with depth tracking to 400 meters (1,300 feet)
  • Integrated fast-response water temperature sensor
  • 12-pin connector compatible with Furuno TZTouch3 12" and 16" displays
  • Bronze housing suitable for stepped, planing, or displacement hulls
  • Exclusive Xducer ID® technology for automatic transducer recognition
  • Urethane acoustic window for reliable signal transmission
  • 9-10 meter (30-33 foot) cable length with 95mm (3-3/4") hole size

Technical Specifications:

  • Functions: Depth and water temperature
  • Maximum depth capability: 400 m (1,300 ft)
  • Temperature range: -10°C to 40°C (14°F to 104°F)
  • Hull material compatibility: Fiberglass or wood
  • Maximum vessel length: Up to 11 m (36 ft)
  • Housing material: Bronze
  • Mounting style: Tilted element thru-hull
  • Weight: 2.7 kg (6 lbs)
  • Country of origin: USA

The B175MW medium ultra-wide model pairs perfectly with other Airmar transducers like the B275LHW to provide comprehensive frequency coverage from shallow to deep water, giving anglers the versatility to target any species at any depth. Professional installation on fiberglass or wood hulls is recommended for optimal performance.
