I would like to find a machine for my wife. She wouldn't use it unless it was simple. I think lightweight would be good for her as well as my mxt is almost too heavy for her. She would just be happy looking for coins so I am leaning toward the M6. I would use a 5.3 or 4x6 with it to hunt parks and schools and to lighten it up. Is it lighterweight than an mxt? will it hunt coins as well as an mxt? is it easier to use than most others? any help appreciated. Oh by the way we would be interested in a nice used one as I am in the hole on my mtx.
