I have been a Lowrance user for quite a while so I hope what I am about to say is wrong. I spent about $ 6oo.oo on a Elite 7 HDI. I have had problems from the beginning. I have talked with CS and was sent a new transducer.(no help)I have tried adjustments, soft resets, hard resets,and various speeds. Nothing seems to help. Today I went about 200 yards with NOTHING on the screen. I think it is the unit, which by this time is out of warrrenty. To call CS again and send in my unit will probably get me an offer for a new unit(with chirp) Is this the old game of keep the buyer paying. I would GLADLY go back to my x 510 that I sold to buy this unit. This unit has never produced the pictures or hype that it was supposed to have. GPS and 2d seem to work O.K.. I realize this is nothing but a computer, but a little better testing would have prevented this and would have made a satisfied customer. If I was to buy another unit, I believe I would look at anothe rsupplier. I have a friend with an Elite 5 HDI and is having problems very close to mine. Miss my X 510 C. Wish I could go back......crappie1133
