I got my used X-70 yesterday, and couldn't wait to try it out this morning, so I went to a place that I have hunted hard for 30 years, and really hit hard this summer. There were NO signals, and I realized how good I had covered it prior to today. Then, I found 3 beer cans at over a foot deep, and hadn't detected them before. I kept going, no coins, pulltabs, hair pins, foil, NOTHING. Almost ready to give up, when I got a nice tone showing a value of only 8, at 4" deep. Gold with diamonds!! Can't make out if it's 10 or 14k, but I'm happy. I "bonded" with the 70, and my arthritis isn't killing me from swinging it. Thanks to y'all for the tips on setting this thing up!!!
