Description and Specifications

Airmar DT820BV-235-N2 235 kHz Low Profile Tilted Element™ Smart™ Sensor 20° Tilt Bronze NMEA 2000

Airmar has taken its proven Tilted Element™ and broadband technologies and applied them to its leading line of Smart™ Sensors. The DT800 is a low-profile, retractable, thru-hull sensor that computes accurate depth and temperature data and sends it to any NMEA 0183 or NMEA 2000® display. The DT800 operates at a frequency of 235 kHz and can run simultaneously with other Airmar 50/200 kHz transducers on-board with no interference. The broadband ceramic delivers depth readings to 183M (600'), as well as accurate shallow-water readings in as little as 500 mm (1.6').

Airmar's Smart™ Sensors have embedded microelectronics - the transducer element and signal processor are only millimeters apart. The signal from the depth transducer is processed right inside the sensor itself. All that is needed to receive depth and temperature data is a single cable into a compatible device or display. Because the ceramic is tilted inside the housing, the transducer beam is oriented straight down, resulting in strong bottom echo returns and accurate depth readings. The retractable housing with a self-closing valve reduces water flow into the vessel when the transducer is removed for cleaning.

FAQs

Please read our FAQs page to find out more.

When will my order ship?

For in-stock items, orders placed by 4:00 PM EST are eligible to ship the same day. If any item in the order is not currently in stock, shipment timing will depend on availability.

What is your return window?

Eligible merchandise may be returned within 30 days from the date of receipt. All returns require a Return Merchandise Authorization (RMA) number before anything is sent back. For the smoothest experience, we ask customers to contact Salina Vita first so we can coordinate the request properly. Returned merchandise must be complete, in its original packaging, and in resalable condition. Items that arrive incomplete, improperly packed, or not suitable for resale may not qualify for return approval.

Are restocking fees possible?

Yes. Approved returns may be subject to a restocking fee of up to 15%. Non-stock items may not be returned. In addition, opened or unsealed DVDs, CDs, and cartography products are non-returnable unless defective. If the product falls into CWR’s excluded media categories—such as opened or unsealed cartography, DVDs, or CDs—it is not returnable unless defective.

If my unit needs warranty service, should I send it back to Salina Vita?

No. Units requiring service, whether under warranty or otherwise, should be returned directly to the appropriate manufacturer, not to Salina Vita. We are always happy to help guide you to the correct manufacturer support path. Absolutely. While the service destination is the manufacturer, we can help you identify the proper support channel and make the process feel more straightforward and well-managed. Units that require service themselves, however, should go directly to the manufacturer under CWR’s policy.

I still have more Questions, can we contact you?

At Salina Vita, we believe premium marine commerce should feel measured, transparent, and reassuring. If you have a question about a shipment, return eligibility, or manufacturer service, contact us before taking the next step and we will guide you with the discretion and clarity your vessel deserves.
