Garmin Airmar B75H CHiRP Bronze Thru-Hull Transducer - 600W. Condition is Used. Shipped with USPS Ground Advantage.

This transducer is five years old and was working perfectly . It failed I bought a new 1000 watt unit and when I was removing it found the cable chewed in half by squirrels.

I’m an electronics tech by trade and cleaned up the wiring and soldered the wires together . I also individually shielded the power wires then shielded the entire group before using vulcanizing tape and RTV with heat shrink to waterproof.

I would not put the splice underwater but in a typical bilge this will hold up for a long time.

Now there is twelve foot of cable either side of the splice, 12 foot to the ducer and 12 feet to the mating connector , think about that before bidding as the splice will not go through a small hole.

I hooked it up to my garmin 1243 sv and it works perfectly, I will guarantee it works fully including reading temp upon installation.

The garmin mating cable in picture is included this must be used to change the 12 pin airmar connector to the 8 pin garmin connector on the rear of your MFD.

So if you want a through hull at a fraction of what they cost new here’s your deal.

Ask any questions

I’ll answer a few, this has zero tilt where it was placed in my MAKO I never lost bottom regardless of seas or speed

I could ping bottom up to 1000 feet but not see fish or much structure that deep

I could see ledge structure and fish up to about 600-700 feet
