Traditional sonar is the best 200/50 khz for macarel,blue fish tuna and etc.I recommend trolling fishing.

This is my second sonar. My first was an in hull puck transducer that I epoxied to the hull. It failed the same year I got it. I learned my lesson. I used plumber putty to install this transducer in the hull. So far it works great and if it fails I can remove it easily and send it back to Garmin.

Defective unit and Garmin will not issue a refund. Unit is in original box and condition I simply plugged it up to see if it would work and it didn’t. I never installed or wired anything in or on! Unit is defective please issue a refund?!

just like OEM!

I ordered this transducer to replace a broken one(same part #). In the “questions asked”, a user asked if it was 4 pin, which is what I needed to replace part. It was answered “yes” more than once. I received transducer and it was NOT a 4 pin. I ended up having to order an adapter. I run a marine servicing business and this was for a customer. Not only did it set me back a couple days, the customer was not able to use his boat to go fishing like he planned.

Just arrived and it’s not a 4 pin like previous folks said. Have to return it. Messed up our last day of rock fishing before the 2 week ban starts this weekend!

Opened the box and inside was a used old transducer super embarrassing to the customer and his boat that I was workin on super pissed off
