Hi Denny,
I can understand your problems because I have been through them myself. Where you are hunting can be one reason you are not finding a lot of coins and more relics. You need to hunt areas where lots of people have congregated in the past. Old school grounds, Old city parks and Ball Parks As well as soccer fields. They are hunted by many folks but there is still plenty of old coins there if the places are old. I recently found a pocket drop of a standing liberty quarter, two Wheaties, and a buffalo nickle in the same hole about 6 feet from a picnic table at 3 inches deep. Your detector is capable of finding coins 6 to 10 inches deep. the way to find the deep coins is to sweep your detector very slow and brush the soil with the coil. In trashy areas you may be swinging to fast and the detector does not have enough time to recover from the last target so you can hear it. I have a long way to go and have gained enough experience to feel the Minelab detectors are truly silver magnets used properly. You must remember you have to sweep over silver to find it. I have found more silver with this detector than 4 other ones I have bought. I now I am reaching the experience that will put me in the league of some of my friends I detect with. There are days I beat them in finds so I know this machine works.
Best of luck in the future.
