I just unboxed my GM1000 today and gave it a test run in my back yard. I allowed the balance on the start up. This is what I have noticed so far. On discrimination mode, my GM still chirps and beeps like crazy. On all metal there chatter literally everywhere. This means the ground at my house is nothing more than a bunch of non-ferrous metals and iron. I also noticed that if I run my hand over the coil (wearing NO rings), it beeps just like it would on a target. I tried putting it on the auto-balance, and I ran it over the same piece of gold over, and over, and over, and it never balanced out. I thought that when you run it over an area it was supposed to zero out that mineralization or trash type? It didn't do that for me. I've watched tons of videos and feel like I have a good grasp on it so I'm not sure what I am doing wrong. I did the start up, got a reading of the ground, placed my piece of gold down, and scanned over it a few times while I tried adjusting sensitivity. I adjusted sensitivity to the point where the gold still would sound off and the ground around it. Also, the display reading on every target I found couldn't decide if it was an iron indicator or a gold indicator. Any advice would be great or links to forums of people discussing the tips and tricks of this.it [

The GM 1000 does not do a ground balance on the initial start up,the initial start up it does the auto frequency once that is done start hunting I ran into the same issue with the GM it does the ground balance automatically but what you will find if you are in the all metal mode if the GM sensitivity is set to high it gets real chatty set it in auto sens or auto sens + and I would almost bet you will find it quiets right down like I stated in an earlier reply to this post the GM 1000 is the simplest detector I have ever used and I really love the simplicity of it it is so simple that you can over think it, the meter on the GM is pretty accurate as far as if it is reading non ferrous then it generally is non ferrous,one thing I do notice with the GM 1000 if you are in the manual sensitivity and you have the manual sens to high or 10 being how sensitive the GM is it gets really noisy most ground I hunt in I run the sensitivity in manual at 8 or less and a lot of times I am as low as 5, most of the time I am running in auto sens or auto + though also why would you ever try to get it to balance out gold Iron targets I could understand but gold targets never to me the GM 1000 kind of reminds me of a Tesoro Lobo super trac which does not balance out gold either but does balance out iron objects or ferrous objects non ferrous the GM does not balance out at least that is what I have observed
