((THIS HAS SOLD))
I’ve got a Garmin GPSMAP 540s with an Airmar P66 transducer. Includes all cabling and the tilt/swivel mount. Just pulled it off the boat to upgrade to something newer. $225 or best offer.
That’s a good unit. I have the 441s and am also considering something newer/bigger.
“Apathy is the Glove into Which Evil Slips It’s Hand”, but really, who cares?
Since a few people have asked: The transducer is 6 pin. It plugs into a port on the power cable, and then one single cable plugs into the back of the 540s.
