Got my Quattro today and rushed out before dark and hunted a vacant lot for about 30min. before it got dark. This is a totally different machine than what I am used to but I like it. The field was loaded with rusty wire pieces which made hunting difficult. The 8in. coil would have worked better here. I hunted all metal mode and dug the high tone signals. Can you believe the first target was a ring. It is a junker but sure got the adrenalin flowing. Hope this is an omen of things to come. I found the pinpointing to be dead on. I have alot to learn about this machine but I like its music already. Going to try to get to the beach tomorrow and will let you know how it does there. Good luck to all. Later, Ken
