I'm now very close to being able to purchase a quality metal detector and believe while depth isn't everything, it sure helps you make the older finds. I am trying to decide between the Quattro and Explorer. I like what I read about the Quattro but read that it is deeper on beaches and the Explorer is deeper on land. I never have hunted water and mostly will be hunting for civil war relics and coins. I know of some areas that I will hunt that will be laden with "aluminum artifacts" although most of the areas I hunt are not too trashy. I love gadgets so the adjustments won't intimidate me. Any input would be appreciated.
