I have a quattro headed my way and can't wait to try it out. I have been detecting for several yrs. and still learning. I have read alot about the quattro and seems like you either love it or hate it. I have been using the MXT for the last couple of years. It is a good machine but now that I have moved to southern california and have access to the beach I needed a uint for the wet sand. From what I have read the quattro is a killer on the beach.Lookin forward to trying it out and learning its language. The info provide by all of you on this forum has already been a great help to me. I wish all of you the best of luck and hope you make that find of a lifetime. I am sure I will have lots of questions and hopefully we can learn together and get the very most out of this machine and this hobby. Hope everyone has a merry christmas.
