<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 DST810-BV-N2 Smart Multisensor delivers depth, speed-through-water, water temperature, and boat attitude data in a single bronze through-hull transducer. Featuring the advanced Gen2 paddlewheel and NMEA 2000 connectivity, this 235kHz transducer provides industry-leading performance with ultra-responsive speed sensing that starts below 0.3 knots and maintains accuracy through 45 knots.

Advanced Speed Performance:

The Gen2 paddlewheel technology delivers best-in-class speed-through-water performance, becoming linear at just 0.6 knots while maintaining smooth, accurate readings throughout the entire speed range. The DST810 outputs speed data at 5.7 Hz (5 times per second) for visibly smoother reporting and faster data updates when split-second decisions matter.

Key Features:

  • 235kHz operating frequency for accurate depth measurement
  • Ultra-responsive speed sensing begins below 0.3 knots, linear at 0.6 knots
  • Maintains accurate speed-through-water readings up to 45 knots
  • 5.7 Hz speed output delivers data 5 times per second for smoother display
  • Integrated attitude sensor provides heel and trim data
  • Bronze housing for durability in saltwater environments
  • NMEA 2000 connectivity for seamless network integration
  • Compatible with Airmar's free CAST app for wireless calibration

CAST App Calibration:

The DST810 works with Airmar's CAST app to provide simple, intuitive calibration from your mobile device. Perform basic and advanced heel-compensated speed calibrations across multiple heel angles and speed ranges without expensive PC-based software. The app enables manual speed entries for up to 10 different speeds and multiple heel angles, ensuring optimal accuracy across all sailing conditions.

The combination of water temperature, depth, upgraded speed resolution, and attitude sensing makes the DST810-BV-N2 a comprehensive solution for sailors demanding precise, reliable multisensor data.

My mechanic said this right cost twice as much. The price was great. Thank you.

The purchasing process was easy...no problem. Waiting to see how the rest of it goes before I rate further (shipping, product condition, etc.)
