Sorry but no we don't ever go to cumberland. We live in Elizabethtown so we don't get down that way. Go check out the Sonar/GPS Installation & Operation forum on BassBoatCentral.com there are quite a few screen shots that people have taken from theirs if that will help.
thanks for the reply, I bought my boat, from a man that lives in elizabethtown. his name is carl. does the structure scan show fish better than the 2d transducers do?
