I have composed this comment and deleted it, but It is time to speak my peace. Maybe you are one of the fortunate ones who received a sonar unit that worked as advertised. I bought a Lowrance Elite 7 HDI when they first came out at about $700.00 bucks. That is a lot for an accessory.(at least to me) It never performed on DI as advertised, or as the screen shots shown on this forum. To pay this much and only receive a one year warrenty is kind of hard to swallow.I have always used Lowrance products as I don"t like Humminbird taking part of the screen on the left side to give depth, water temp, etc. instead of overlaying this information. EVERY unit should be tested for performance and a tester should have to stand behind his results. If they can hold you off until the warrenty expires, then they can offer a refurb unit at about half of the cost of the original unit. Lowrance calls this the" Advantage Plan". Guess who has the advantage? Under the thread "Humminbird 998" , Ricky stated that he just paid 697.50 on his Hunninbird 997. It's kind of like catching a fish.....once you hook um, keep winding. My only experience with Garmin was a monocrome 160 unit.(worked good) I believe if I were in need of a new unit, I would have to try a different company.....enough venting ....Thanks for everyones patience and understanding. Hope everyone has a good winter......and stay warm......crappie1133
