Bought a used “93sv UHD with transducer” yesterday and got everything installed and I notice the display unit says “EchoMAP Plus 93sv” on the back and also in the system info. Shouldn’t it have “UHD” somewhere in the info and on the back? Did I buy a regular EchoMAP plus with a UHD transducer? Everything was in the box and most of it hadn’t even been opened and I didn’t even think to check.. why would I, right?.... anyways.. did I get duped or is this right?
