Have a couple of graphs for sale. They all work fine and nothing is wrong with them. Just looking into buying a Lowrance X-15mt with GPS. I have a Lowrance X-65 with transducer for $160, A Pinpoint 7420 (only a year old paid over $500) with speed and temp transducer for $375, and a Lowrance X-16 paper graph with gray scale with extra rolls of paper and extra stylus for $285. if interested e-mail at jj6987@yahoo.com
