i'm using it for about a month already.
i believe sometimes its not about looking at the display, but listening to the sounds. but i do believe sometimes its up to your own feeling whether you decide to dig the stuff.
- pull tab sound off around med tone
- batteries sound off in all kinds of tone, low,med,high
- keys sound off in med,high tone
- coins sound off in low,med, high tone depending on whether there's oxidization on it
- nails sound off in low tone, very low tone
but i do know that gold sound off in low tone. tried some gold objects. got to increase the sensitivity to about 2 o'clock position and disc to 10 o'clock when i get sounding off the detector.
hope that helps.
anything to share with me about this detector? i'm still new too.
cheers
