Airmar DST820-PV-N2 Smart Multisensor PSTI Plastic Thru-Hull Bluetooth 235kHz

The Airmar DST820-PV-N2 is a DST820 Smart Multisensor, a plastic thru-hull transducer with Bluetooth and a 235kHz operating frequency. It measures speed through water, depth and water temperature. It replaces the DST810 and adds PSTI compliance for better onboard network security.

Key Features:

• Gen2 paddlewheel for speed-through-water readings, with start-up data below 0.3 knots, linear accuracy from 0.6 knots, and stable readings up to 45 knots
• 5.7 Hz speed output with improved resolution, for smoother speed reporting
• Depth tracking from 0.5 m (1.6 ft) to 100 m (328 ft)
• Also measures water temperature
• Integrated attitude sensor gives heel and trim data and supports heel-compensated speed calibration, independent of onboard instruments
• Secure Bluetooth connection to Airmar's free CAST app for basic or advanced speed calibration from a smartphone or tablet
• QR-code setup: scan the code and enter a one-time security password to protect the sensor on the network
• Compliant with UK PSTI security standards for the connection between the sensor and a mobile device
• Urethane acoustic window

Accurate speed-through-water data helps with sail trim, rig balance, and velocity made good (VMG) and target speed calculations on racing instruments. It suits day sailors, cruisers and racers.
