Overview
The Garmin 010-12445-33 is a transducer Y-cable that connects a 12-pin (orange) scanning transducer and an 8-pin (blue) 2D transducer to a single 12-pin sounder port on compatible Garmin sonar units.
It is commonly used to run a GT30 transom-mount scanning transducer alongside an in-hull traditional transducer such as the GT15M-IH, GT8HW-IH, Airmar P72, or Airmar P79. With this setup, the display can keep showing water depth from the in-hull transducer when the transom transducer loses bottom at speed or in aerated water.
Key features
- Y-cable format: 12-pin (orange) sounder connection with separate 12-pin (orange) and 8-pin (blue) transducer legs
- Supports pairing a 12-pin SideVü/ClearVü-only transducer with an 8-pin 2D-only transducer on one compatible port
- Helps maintain depth readings from an in-hull transducer when the transom mount is affected by cavitation or excess speed
- Useful on planing hulls where the transom transducer can be intermittently aerated while underway
Compatibility and fit
This adapter is for Garmin chartplotter/sonar units that use the 12-pin (orange) transducer port and support the 12-pin plus 8-pin Y-cable arrangement. It is intended for the specific mix of one 12-pin scanning transducer and one 8-pin in-hull 2D transducer.
Confirm the connector style before ordering. If your display or transducer uses a different plug style (such as 4-pin, 6-pin, or 8-pin at the display end), this cable will not match.
Installation and setup
Install the cable at the back of the display and route both legs toward their transducer cable runs. Leave enough service loop to avoid strain at the connectors, and support the wiring so it does not chafe in vibration areas like the console chase or rigging tube.
Keep all connections clean and fully seated, then tighten the connector collars by hand. After installation, verify that the unit is reading depth at idle and again on plane to confirm the in-hull transducer is carrying depth when water flow gets turbulent at the transom.
