Don't know if I have the right forum for this but here goes. I have a hummingbird fish/depth finder. It's a small cheaper one. When I'm just cruising under 15 mph the depth and temp numbers are correct, but when I get going on plane and in a little rough water the numbers are crazy. If I'm in 25' of water it will say 450, fish will show 120' and then sometimes it will say 0. As soon as I slow down say under 15mph everything goes back to normal. Is there a problem with the unit or is the transducer screwed up. Thanks-Russ
