DST-820 Plastic Thru-Hull Triducer Multisensor with 6M CableThe DST820 Smart Multisensor is the next evolution of Airmars industry-leading technology, replacing the DST810 and introducing PSTI compliance for enhanced onboard network security.With its secure QR-code setup, connecting your DST820 has never been easieror safer. Simply scan the QR code and enter a one-time security password on your mobile device to protect your sensor on the network.Featuring Airmars high-performance Gen2 paddlewheel, the DST820 delivers unmatched speed-through-water accuracy providing precise start-up data below 0.3 knots, linear accuracy from 0.6 knots, and stable, reliable readings all the way up to 45knots.Whether youre a day sailor, weekend cruiser, or tactical racer, accurate speed-through-water (STW) data helps you fine-tune sail trim and rig balance for maximum performance. For racers, precise STW readings enable accurate velocity made good (VMG) and target speed calculations, ensuring every tactical decision is data-driven.Together, the DST820 and Airmars CAST app make speed calibration simpler than ever. The free CAST app provides powerful calibration toolsonce only available through costly PC-based softwarenow instantly accessible from your smartphone or tablet. Choose from basic or advanced calibration options to suit your needs.Beyond speed, the DST820 measures depth and water temperature, and provides a 5.7 Hz (5 per second) speed output with improved resolution. Its integrated attitude sensor delivers heel and trim data, enabling heel-compensated speed calibration across multiple heel angles and speed rangesfast, intuitive, and completely independent of onboard instruments.With depth tracking from 0.5 m (1.6 ft) to 100 m (328 ft), the DST820 also provides reliable depth data to help ensure you never run aground.The result: industry-leading speed accuracy, wireless calibration convenience, and next-generation securityall in one powerful, compact sensor.Features:The DST820 is fully compliant with UK PSTI security standards, ensuring that the connection between DST820 and a mobile device is secure.The industrys best speed paddlewheel DST820 features the Gen2 paddlewheel for industry-leading speed performance from 0.3 knots to 45 knots.Smoother Speed 5.7 Hz speed output (5X per second) for visibly smoother speed-through-water reporting and faster data for better decision-making when every second counts.Integrated Attitude Sensor For heel and trim and used in advanced speed calibration.DST820 secure Bluetoothconnectivity to Airmars CAST app provides the ability to:Calibrate the DST820 in a simple, intuitive way from your mobile device.Conduct basic and advanced heel-compensated speed calibrations for improved speed-through-water outputs across the speed range.Advanced speed calibration allows for manual speed entries for multiple heel angles and up to 10 speeds, formerly only possible through expensive PC software.Specifications:Functions: Depth, Speed, Temperature, AttitudeMounting Style: Low Profile Thru-HullPower Rating: 80 WProtocol Output: NMEA 2000Housing: PlasticMax Deadrise Angle: 22Hull Material: Fiberglass or metalHole Size: 51 mm (2″)Retractable housing: YesAcoustic Window: UrethaneAttitude Sensor: YesBluetooth Capable: Yes, Bluetooth BLECable-Length: 6 m (20′) NMEA 2000 cableCertifications: CECommon Use: Cruising/Racing Sailboats, Leisure/Yachting, FishingConventional Beam: 10x44Data Rate: Depth: 1X/second, Speed: 5X/second, Heel/Trim: 10X/secondMax Deadrise: Up to 22Max Depth: 0.5 m (1.6′) to 100 m (330′)Minimum Depth: 0.5 m (1.6′)NMEA 2000 LEN: 2Pulses: 20,000 p/nm* (5.6 Hz per knot)*p/nm = pulses per nautical mileRetrofits: Fits most Airmar 2″ housingsSpeed Rang
