Overview

The Garmin 010-10272-00 is a dual-frequency 50/200 kHz transom-mount transducer that reads depth and water temperature through a 6-pin Garmin sonar connection.

It runs 500 W (RMS) and is rated for depth readings down to 1,500 ft in the right conditions. The plastic transducer body mounts on transoms from 0 degrees to 70 degrees, and the attached 30 ft cable gives you room to route up to a console, helm, or electronics box.

Key features

• Dual-frequency operation at 50 kHz and 200 kHz for traditional sonar use
• 500 W (RMS) output with a published maximum depth rating of 1,500 ft
• Built-in temperature sensor for water temperature readout on compatible Garmin displays
• 6-pin transducer plug for Garmin sonar ports that accept 6-pin connections
• 30 ft attached cable for routing to a display or sonar module
• Transom mounting hardware supports installations on 0 degree to 70 degree transom angles

What’s included

• Depth and temperature transducer with attached cable
• Transom mounting bracket
• Mounting hardware
• Installation instructions

Compatibility and fit

This transducer connects with a 6-pin Garmin plug. If your sounder or sonar module uses a different transducer port style, match the connector with the correct adapter cable so the pin count and plug style are correct.

This is a traditional 50/200 kHz transducer for standard depth and fishfinder functions. It is not a CHIRP or imaging transducer.

Installation and setup

Mount it where the transducer face will see clean water flow. Keep it away from strakes, intakes, and other fittings that introduce turbulence or air bubbles, and avoid the propeller path on single-drive boats. On twin-drive boats, placing it between the drives is often the cleanest flow.

Seal screw holes with marine sealant, route the cable away from high-current wiring to reduce interference, and support the cable run so vibration does not chafe it over time. Avoid cutting the transducer cable.

Use cases on board

Switching between 200 kHz and 50 kHz helps you tune what you see under the boat based on depth and the kind of bottom you are running. The temperature sensor is useful for tracking water changes while fishing and for keeping an eye on conditions during coastal cruising.

This setup is a practical fit for skiffs, bay boats, small cruisers, and sailboats that already have a Garmin sonar input that accepts a 6-pin transducer.

Maintenance and care

Rinse the transducer and bracket after saltwater use and check that the mounting hardware stays snug. If bottom readings drop out at speed, recheck that the transducer remains parallel to the waterline and has not shifted after a light impact or trailering.
