Hi All,
There has been a discussion about trying to use a PI for coin hunting on another forum and part of that discussion talked something brought to my attention by a GS 5 owner, and that was he could set the ground balance control such that high conductors such as silver and copper would generate a low tone and all ferrous objects would create a high tone. Well, after some experimenting I found this to be true.
Now, the GS 5 has the capabilities of turning off either high or low tone with a mod or two. (Actually, a switch has to be added). So, guess what, I just had to try it and add the switch. Then I set the GS 5 such that silver, copper and clad coins generated a low tone while iron objects still cause a high tone. Now, this GS 5 does not have the capability to switch tones, but that is ok.
What I ended up with is a PI that ignores small foil junk, iron junk but sounds off on copper, silver and clad coins. So, far, my testing has been limited to my yard and more needs to be done it is looking real good. Simple surface tests work great. Then, I did bury a penny about 6" to 7" deep just to see how well it worked on a buried coin. Wow, it worked great there also. I was able to raise the coil about 5" or so and still hear the target and that was with the sensitivity down to reduce the noise.
When time permits, I really do have to try this setup for coin hunting.
Just thought people might want to know.
