<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 B175H is a high-frequency CHIRP transducer designed for smaller boats such as center consoles, featuring a low-profile bronze housing ideal for fiberglass or wood hulls. This flush-mounted bronze housing protrudes less than 1/4-inch outside the hull and can sit on trailer rollers or bunks without damage.

High-Frequency CHIRP Technology:

  • CHIRPS from 130 kHz to 210 kHz with 15° to 9° beamwidth
  • 80 kHz of total bandwidth in just one installation
  • Narrow beamwidth excellent for pinpointing fish holding tight to wrecks, reefs, and other structures with amazing target separation on baitfish and schooling gamefish
  • Bottom detection down to 3,000m (10,000') with 5 to 10 times greater detail and resolution

Tilted Element Design:

  • 12° tilted element inside the transducer accommodates all hull deadrises and eliminates the need for a fairing block
  • Installed almost flush to the hull, the tilt corrects for the hull's deadrise and orients the ceramic element horizontally to ensure maximum echo returns
  • Supports vessels with maximum deadrise angles up to 24 degrees

Key Features:

  • 1 kW power rating for reliable performance
  • Depth and fast-response water-temperature sensor
  • Durable bronze transducer housing
  • Exclusive Xducer ID® technology
  • Recommended for vessels up to 36 feet (11 meters)
  • Suitable for stepped, planing, or displacement hulls

Important: This transducer requires a separate Mix and Match (M&M) CHIRP cable for connection to your compatible fish finder or sonar system. The Mix and Match connector allows you to select the appropriate cable for your specific electronics brand (Garmin, Raymarine, Humminbird, Furuno, etc.).

Superior shallow-water performance and bottom detail make this transducer ideal for serious anglers, commercial fishermen, and charter captains seeking professional-grade sonar imaging.

Found the best price for the tires I needed here. Mixed production years but can't complain for the price. Arrived very quickly.
