I sure wish I had got one sooner. I had just a little free time this afternoon and run back down to the beach. Found several coins,one was a 1916 buffalo nickle. The more I use the quattro the more I like it. It sure does a good job on the beach. There was a lot of iron where I was hunting but I worked it slowly and came up with some good finds and some were very deep among the iron. I learned to do the wiggle when i got just a hint of a good signal and it would lock on to the good target. It is a different machine from anything I have ever used. There was a guy hunting with a PI machine and he had to give up because of all the iron.
