Hey playingInTheDirt, I have one, but this is my first metal detector and I've only had it a month. So I'm not going to be of much help since I'm not experienced at all. I do have a hard time with it "chattering" in my back yard but this yard has more things buried in it then a landfill. I'm just now getting the hang of it. I can tell you it's so light you'll never have a problem swinging it for hours and hours, my battery has lasted so for about 26 hours. I was going to change it out today just because I thought maybe the battery reading wasn't working but after checking others who has had this machine they claim to run their battery 40 or more. Good luck, I hope you love this machine, great price since I paid $499.00 for mine new. So even if you don't like it you can sell it for a profit. HH
