Garmin Airmar DST 810 Smart Thru-Hull Transducer, NMEA 2000, Depth/Speed/Temp, Attitude Sensing, Bluetooth, 0 Deg Tilt

Overview

The Garmin 010-11051-20 is a low-profile thru-hull smart transducer with a plastic housing that outputs depth, speed-through-water, water temperature, and boat attitude data (heel/trim and pitch/roll) over NMEA 2000. It operates at 235 kHz with 100 W power, uses a 10 x 44 degree beam, and provides depth readings to 330 ft.

Speed data updates at 5 Hz (five times per second) for smoother readouts at the helm. Built-in Bluetooth connects to the Airmar CAST app for offsets and calibration without needing to pull out a laptop.

This is the 0 degree model and it fits a 2-inch (51 mm) thru-hull cutout. It accommodates hull deadrise angles up to 22 degrees, with best performance on lower-deadrise installations.

Key features

• Single thru-hull sensor for depth, speed-through-water, and water temperature, plus attitude data (heel/trim and pitch/roll) on NMEA 2000
• 235 kHz, 100 W depth element with a 10 x 44 degree beam and depth readings to 330 ft
• 5 Hz speed output for faster updates on compatible displays
• Bluetooth link to the Airmar CAST app for sensor offsets and advanced speed calibration, including heel-compensated calibration
• Gen2 paddlewheel performance from about 0.3 knots up to 45 knots
• 0 degree model fits a 2-inch (51 mm) thru-hull hole and supports hull deadrise angles up to 22 degrees
• IP68 dust and water ingress rating for below-the-waterline use
• Attached NMEA 2000 cable length of 20 ft for routing to the nearest backbone connection

Compatibility and fit

This transducer is meant for an NMEA 2000 network and shows up as a network sensor for depth, speed, temperature, and attitude data. It is an instrument multisensor and does not replace a dedicated sonar or fishfinder transducer.

The plastic housing is suited to fiberglass or metal hulls. Avoid installing a plastic housing in a wood hull where swelling can stress the fitting.

Installation and setup

Plan the mounting spot where water flow stays clean and the unit remains continuously immersed. Keep it clear of intakes, discharge outlets, strakes, steps, and other hull features that introduce bubbles or turbulence, and make sure the depth beam is not blocked by keel or running gear.

Orient the insert so the arrow points forward toward the bow, seal the housing with a below-waterline marine sealant, and check for leaks right after launch. The retractable insert and housing valve make it possible to service the paddlewheel without hauling, but the insert or a blanking plug still needs to be fully seated and secured for a watertight seal.

Calibration and data output

Bluetooth setup and calibration are handled through the Airmar CAST app. For pairing and adjustments, plan on having your phone or tablet within about 5 m (16 ft) of the sensor location.

Maintenance and care

In salt water, coat surfaces exposed to seawater with a water-based antifouling made for transducers and refresh it at least seasonally. Keep solvents and ketone-based paints away from the sensor face and plastic parts, and periodically inspect and lubricate O-rings when removing or reinstalling the insert.

Use on board

This unit makes sense for sailboats that want heel and trim data tied to speed-through-water calibration, and for powerboats that prefer a single clean thru-hull for depth, speed, and temperature. It is also a practical fit for refits where you want one 2-inch hole to cover multiple instrument feeds.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
