Review on Garmin GT21 TM Chirp DownVu 010 01962 00 by Jonathan Olson

I ordered this sensor to replace a broken one (same part number). On "Questions" the user asked if this is a 4 pin connector that I need to replace the part. Answered "Yes" more than once. I received the converter and it was NOT 4 pin. For this reason I had to order an adapter. I am in the Navy and this was for a client. Not only did this set me back a few days, the customer was not able to use their boat for fishing as planned.
