I have a chance to get a Hummingbird LCR 8000 unit from a dealer that I have gotten to know real well. It is an older unit but still new in the plastic wrap. The list price for this unit is over $1100 and he has said he would let me have it for $250. It sounds like a real good buy but my questions are: How old is this unit? Has the technology on the newer units, Garmin, Lowrance..etc far surpassed this old bird to the point that I would be better off getting something newer. <br /> Any information anyone can give would be greatly appreciated.
