In June my brand new Eagle 480 crapped out after less than 6 hours use. It took Lowrance/Eagle a month to send me a new unit. The new unit lasted less than 5 hours before it crapped out. Less than 1/2 hr. ago I took delivery on a replacement for the second unit..............Guess what..........This one crapped out in 0 hours. This one won't even boot up.
