Description
GT12M Bronze Thru-Hull - 350W - 20 Degree
Designed for reduced drag and optimum sonar performance on midsize fishing and cruising boats, this flush-mounted, 350-watt mid-band CHIRP transducer clearly defines fish arches, structure, and bottom depth returns on your display.
Midband Chirp Traditional Sonar
This 8-pin, 350-watt bronze thru-hull transducer features high-definition mid-band CHIRP sonar that clearly defines fish targets and structures down to 800’ in saltwater and 1,200’ in freshwater.
Broad Frequency Range
Use the perfect frequency for the waters you’re fishing. Covering the medium frequency range, this transducer pulses from 85–165 kHz, displaying a wide coverage area, crisp fish arches, and accurate depth readings.
Optimum Ping Sensitivity
Offering excellent sonar sensitivity, low noise, high resolution, and good separation of targets, this robust transducer makes it easier than ever to distinguish fish and structure on your compatible chartplotter display.
Thru-Hull Installation
A durable bronze housing and stem offer straightforward thru-hull flush mounting for minimum drag and optimum beam orientation for clear sonar returns.
Auto-ID Technology
Enjoy simple plug-and-play operation with Garmin auto-identification technology — which enables the sonar to automatically configure itself to the transducer being used.
Fits Various Hull Types
Configurable for a wide variety of boat hull materials, including fiberglass, composite, and wood, the transducer is available in a range of tilt versions to accommodate deadrise angles of 0–20° without a fairing block.

Where Have You Been All My Boating Life?
What a great little piece of tech - I don't know how we got by without it in the past. No more guessing how full the holding tank is or having to clean icky tank senders. This little bluetooth RADAR sending unit mounts on top of the tank and connects wirelessly to our Victron Cerbo.
Setup is super easy, push the button on the unit so it can calibrate to the tank then enable bluetooth and set up your rank dimensions on your Cerbo. It's as easy as that.
We've had it installed and running for about two weeks now and couldn't be more pleased (We like it enough that I ordered a second one for our water tank.)
Lots of wiring - no leaks! Be sure to run ALL the wires through BEFORE completing the run!

"Currently" super happy.
Installed on Yanmar 4JH57 engines with Zeus Controllers - HOLY WOW power. Losing some power at top end but overall very satisfied. Will do a long term review later. Talk about power - hope to never need my generator again!
