DST810 Smart Multisensor 23kHz Bronze NMEA 2000 Transducer - N2KDepth, Speed-Through-Water, Water Temperature, Boat Attitude! The DST810 Smart Multisensor, featuring the new Gen2 paddlewheel and AIRMAR's CAST app, delivers a powerful combination of best-in-class speed performance and a simple, reliable way to calibrate accurate speed using your wireless device. The Gen2 paddlewheel delivers industry-leading start-up speed-through-water data below 0.3 knots and is linear at 0.6 knots, maintaining accurate performance up to 45 knots.The DST810 and CAST app provides a simple, consistent way to calibrate speed through the water. The free CAST app delivers calibration options that, until now, were only available through expensive PC-based software. In addition to water temperature, depth, and upgraded 5.7 Hz (5X per second) speed-through-water output with improved speed resolution, the DST810 features an integrated attitude sensor for heel and trim data. This information, combined with Airmar's powerful and simple CAST app, makes heel-compensated speed calibration across multiple heel angles and speed ranges fast and intuitive, and is independent of the onboard instruments.Features: 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.; Wireless connectivity to AIRMAR's CAST app has new user-friendly benefits: Calibrate the DST810 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.; Ultra-responsive speed begins as low as 0.3 knots and becomes linear at 0.6 knots.; Speed-through-water readings stay accurate and smooth through 45 knots.; ; This product may not be returned to the original point of purchase.
