Description
The GT34UHD-TM Transducer is a Garmin marine transducer designed to provide depth, temperature and/or scanning-sonar information to compatible Garmin sounders and chartplotters. Correct hull material, mounting style, connector type and sonar compatibility should be confirmed before installation.
Main Features
- Garmin-compatible marine sonar transducer
- Purpose-built underwater acoustic sensor for compatible Garmin sounders
- Marine installation hardware suited to the listed mounting style
- Temperature and/or depth capability as supported by this model
- Match connector, frequency and hull installation requirements before ordering
Compatibility
Transducers are not universally interchangeable. Confirm the sounder’s connector and supported frequency/power range before purchase.
Installation
Mounting location has a major effect on sonar performance. Avoid aerated water and turbulence and follow Garmin’s deadrise and hull-material guidance for the specific sensor.
Sonar performance
Maximum depth and target detail depend on frequency, power, water conditions, mounting, bottom type and the connected sounder.
System planning
For networked Garmin systems, sonar data can often be shared to compatible chartplotters once the transducer is connected to an appropriate internal or external sounder.
What’s in the Box
Transducer, attached cable and model-specific installation hardware/documentation. Verify included fairing block or adapters for the exact package.
