Detailed description

Designed for navigation and sport fishing, the intelligent through-hull sonar Garmin Airmar DT800 provides accurate depth and temperature data via the NMEA 2000® network. This transducer integrates Smart™ Sensor technology, processing signals directly inside the sensor for immediate digital transmission to compatible multifunction displays, chartplotters, or radars.

Tilted element and broadband technology

The DT800 stands out with its 20° tilted ceramic element, a feature of Airmar’s Tilted Element™ technology. This design compensates for hull deadrise (angles from 16° to 24°) without requiring a fairing block, ensuring a vertical beam orientation for precise readings. Using Airmar’s exclusive Broadband Ceramic technology, the 235 kHz frequency delivers improved resolution without compromising sensitivity. This specific frequency also helps prevent mutual interference with other depth sounders on board. With an RMS power of 100 W and a 12° beam (-3 dB), the DT800 provides reliable depth readings from 0.5 meters and can reach up to 180 meters.

Integration and design

Compatible with NMEA 2000® systems, the DT800 integrates easily into modern marine networks. It offers direct and simplified connectivity, with current consumption under 200 mA at 9 to 16 VDC. Its discreet and retractable housing, equipped with a water valve, minimizes drag and simplifies maintenance without dry-docking the vessel. Compared to other Airmar transducers, the DT800, with its 20° tilted element, is a dedicated solution for hulls with pronounced deadrise angles, offering an alternative to 0° or 12° tilted-element models or transducers requiring an external fairing block, such as non-Tilted Element models.

« Technical analysis of the Garmin Airmar DT800 NMEA 2000 depth sounder »

The Garmin Airmar DT800 transducer is a technically sound solution for boat owners with hulls featuring significant deadrise, typically between 16° and 24°. The integration of the 20°-angled element directly into the transducer housing is a major advantage, as it eliminates the need for an external shoe, which often introduces additional drag or installation complications. This approach simplifies mounting and maintains a more hydrodynamic hull profile.

In terms of system integration, its NMEA 2000® compatibility is a key asset. The transducer functions as an intelligent sensor, providing depth and temperature data directly on the network, reducing wiring and simplifying configuration compared to analog sounders requiring a conversion module. The 235 kHz frequency is a wise choice for installations where multiple sounders operate simultaneously, minimizing the risk of cross-interference.

The retractable housing is also a strong point for maintenance. It allows for quick cleaning or inspection of the sensor without removing the boat from the water, thanks to its integrated water valve. While the plastic housing is suitable for most fiberglass or metal hulls (with proper insulation), consider bronze or stainless steel versions for more aggressive marine environments or installations on metal hulls without adequate galvanic isolation. This model is particularly well-suited to recreational and cruising vessels seeking a reliable and discreet solution for depth and temperature measurement without compromising performance or ease of maintenance.

What is the Garmin Airmar DT800 transducer?

The Garmin Airmar DT800 is an in-hull smart transducer designed for navigation and sport fishing. It provides accurate depth and temperature data via the NMEA 2000® network. It features Smart™ Sensor technology, which processes signals directly inside the sensor for immediate digital transmission.

What is the power output of the DT800 transducer?

The DT800 transducer has an RMS power output of 100 W.

What is the operating frequency of this transducer?

The DT800 transducer operates at a frequency of 235 kHz.

What are the minimum and maximum depth ranges of the DT800 depth sounder?

The DT800 depth sounder can detect reliable depths starting from 0.5 metres (1.6 feet) and can reach up to 180 metres (590 feet).

Does the DT800 transducer measure water temperature?

Yes, the DT800 transducer is equipped with a temperature sensor. It can measure water temperature in a range from -10°C to 40°C (14°F to 104°F) with an accuracy of ±0.5°C (±1.8°F).

What is the beam angle of the DT800 transducer?

The beam angle of the DT800 transducer is 12° at -3 dB.

What is the Tilted Element™ technology and how does it work?

Airmar's Tilted Element™ technology is a unique design where the ceramic element is tilted inside the transducer housing. For the DT800, this element is tilted at 20°.
