I bought a Tesoro Sidewinder UMax for my girlfriend to use for relic hunting. Can anyone give me some info. about the detector? We have good ground here and I was wanting to know how to set it up for Civil War relics and what kind of depth can we get out of the machine. She has been using a old Silver Sabre II for years and she will not try anything else, but she liked the look of the Sidewinder so I bought it for her. Can anyone give me some pointers about the machine. Thanks Bear
