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 B275C-LHW-MM is a high-performance bronze thru-hull CHIRP transducer designed for serious anglers and boaters who demand maximum underwater coverage. This dual-frequency transducer combines low frequency (42-65 kHz) for deep water performance with high wide frequency (150-250 kHz) for exceptional detail in the upper water column.

Wide Beam Technology:

Unlike traditional narrow beam transducers, the B275C-LHW features a constant 25° beam width across the entire high frequency range, delivering twice the coverage under your boat. This wide beam format creates crisper, larger return images on your display while capturing fish that narrow beam transducers might miss in the upper water column.

Key Features:

  • Dual CHIRP frequencies: 42-65 kHz (Low) and 150-250 kHz (High Wide)
  • Constant 25° wide beam angle for maximum bottom coverage
  • 1 kW power rating for deep water performance
  • Integrated depth and temperature sensor
  • Durable bronze housing for thru-hull installation
  • Includes 9-meter (approximately 30 feet) cable
  • Requires Mix & Match cable for connection to compatible fishfinder

Installation Note:

This is a thru-hull mount transducer requiring professional installation through the boat hull. The bronze construction provides excellent corrosion resistance for saltwater and freshwater applications.

Compatible with CHIRP-ready echosounders and fishfinders. Mix & Match cable sold separately for connection to your specific display unit.

best price I saw for this product..could shown estimated time of arrival at checkout

Best price I found. Hope it ships soon.

great service

very quick checkout process. I hope the shipping is as quick! Glad I found the part on here. After part arrived: if the wait time for the order to ship could be reduced, I would have done 5 stars. Good product tho

No complaints. ordered a BAK Industries Truck Bed Cover BakFlip G2 for my Honda Ridgeline on 1/11/12. Package was shipped on 1/13/12 and arrived 1/18/12, delivered undamaged. <br><br>Autoplicity was cheaper than Amazon by about $40 (after shipping), and I didn't need to compromise on service. I would definately use them again.

So far so good.

Quick easy

took a long time to and fro autoplicity to amazon

Great price and fast shipping! If your looking for quality brands at the best price available!!<br>

looking forward to receiving my order!
