As some of you know I was having some trouble with my Lowrance X-15 the GPS worked fine but the sonar was scrambled and I couldn't use the MMC/SD cards in it even with a software update. Thus I used my trusty old X-97. Well about two weeks ago when I was busy with the Restaurant I sent it in to Lowrance. Guess what? They sent me a brand new one! Once again Lowrance has come thru with the type of service they are known for. I know of a lot of people who have had a positive experience with them and very few have had negative things to say. For me there is no other sonar system! Lowrance Rocks! See ya on the water!
