Fitment guidance

  • Thru-hull transducers should be matched to hull material, deadrise angle, installation location, and cable route before drilling or bedding the housing.

Before you buy

Confirm the display model, sonar port, connector, hull material, mounting style, deadrise angle, and cable route before ordering. Some installs require adapters, fairing blocks, sealant, or professional installation.

What to match

Match the transducer to the sonar technology you need: traditional CHIRP, ClearVü, SideVü, Ultra High-Definition scanning, or specialized high-power offshore CHIRP.

Common questions

Will this work with every Garmin unit?
No. Compatibility depends on your Garmin display, sonar port, connector, and supported sonar type.

How do I choose the right tilt or deadrise?
For tilted-element thru-hull models, match the transducer angle to your hull deadrise so the sonar beam points correctly in the water.

Should I confirm before ordering?
Yes. Transducers are highly installation-specific, especially thru-hull, in-hull, pocket-mount, and high-power CHIRP models.
