<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 DST820-PV-N2 is a next-generation PSTI-compliant plastic thru-hull smart multisensor, representing the evolution of Airmar's industry-leading DST810 platform. Designed for NMEA 2000 (N2) networks, this sensor combines depth, speed, and temperature measurement in a single, streamlined installation with integrated Bluetooth connectivity for wireless configuration and diagnostics.

Key Features:

  • PSTI Compliant: Meets the Product Security Testing Initiative (PSTI) standard for connected marine electronics
  • Bluetooth Connectivity: Wireless setup and diagnostics via the Airmar Weather Station Tool or compatible app—no laptop required at the helm
  • 235 kHz Transducer: High-frequency operation delivers superior bottom discrimination and detail, ideal for coastal and inland waters
  • NMEA 2000 Output: Plug-and-play compatibility with modern MFDs and onboard networks from Garmin, Simrad, Raymarine, Furuno, and others
  • Plastic Thru-Hull Housing: Durable, corrosion-resistant plastic construction suited for fiberglass and other non-metallic hulls
  • Integrated DST Sensing: Measures Depth, Speed, and Temperature simultaneously from a single hull penetration
  • Replaces DST810: Direct upgrade path with improved compliance and connectivity features
  • SmartSensor Technology: Built-in tilt compensation and advanced signal processing for accurate readings even at speed or in rough conditions

The DST820-PV-N2 is engineered for recreational and light commercial marine applications where reliable, accurate sensor data and modern network integration are essential. Its Bluetooth-enabled configuration simplifies installation and ongoing calibration, making it a practical choice for both professional installers and experienced boaters.
