I own a Hummingbird 200dx fish finder. It doesn’t read the boat’s speed. What to do?
My Hummingbird 200dx fish finder work okay with exception of the boat’s speed. Speed and tempeture are both suplied via the same cable. I get tempeture but no speed. Is this caused by a defective cable or how the receiver is mounted on the boat transum or something else?

i got the same one on my boat,mine stopped working about a year ago and i replaced the cable which has the sensors in it and it started working again,unfortunately i had to pay for the cable it wasn’t under warranty,but for now it works again,those are pretty good units,the speed part of mine i know isn’t accurate,but at least it works,mine got damaged by hitting something in the water,good luck.
