Description

The Airmar DST820 Smart Multisensor combines depth, speed-through-water, and temperature data with Bluetooth configuration in a plastic thru-hull package. As the successor to the DST810, it adds PSTI-compliant network security with QR-code setup and a one-time password, giving installers a more secure way to connect a mobile device to the sensor.

Airmar's Gen2 paddlewheel is designed for precise speed-through-water measurements, including start-up data below 0.3 knots, linear accuracy from 0.6 knots, and stable readings through 45 knots. Accurate STW data can support sail-trim decisions, rig balance, velocity-made-good calculations, and target-speed work where small changes in boat speed matter.

The 235 kHz depth channel is designed to reduce interference with many common fish-finder frequencies, while the multisensor also supplies water temperature. Bluetooth access allows compatible configuration and calibration from a mobile device, making the DST820 useful for sailors and boaters who want several core vessel measurements from one thru-hull sensor.

Key Features

  • Three important vessel measurements from one thru-hull: Depth, speed-through-water, and temperature data are combined in a single smart multisensor.
  • More precise low-speed water-speed data: The Gen2 paddlewheel is designed to begin producing useful speed data below 0.3 knots and remain stable across a broad operating range.
  • Secure mobile setup: QR-code pairing and a one-time password support PSTI-compliant Bluetooth configuration without leaving the sensor open to casual network access.
  • Depth frequency selected to reduce interference: The 235 kHz depth channel helps separate the sensor's depth measurement from many common fish-finder operating frequencies.

Frequently Asked Questions

How does the DST820 connect securely?
It uses secure QR-code setup; scan the code and enter a one-time security password on your mobile device to protect the sensor on the network, meeting UK PSTI security standards.
What does the CAST app do?
It provides basic and advanced speed calibration tools directly from a smartphone or tablet, including heel-compensated calibration across multiple heel angles and up to 10 speeds.
What is the depth range of this sensor?
0.5m (1.6 ft) to 100m (328 ft).
