I go by conditions. At some areas digging everything means I would be in a small area all day so I give myself 3 chances to find gold by programming my custom mode to accept the foil notch, also. On my Ace that's the same as the Coins mode with the foil notch on. I have found 3 gold rings in the last two weeks doing this. In tot lots, it's Relics mode or all metal and since the diggin's easy I look at everything. In fact, everywhere else except the trash areas I LOVE the Relics mode. In this custom mode, I have 3 chances to find gold-nickel accept, foil accept, and square tab accept(class rings, usually.) Of course I loose the chance to find one in the tab area, but to keep my sanity and enjoy myself under these conditions, I have had great success. Here's the clincher: if you KEEP YOUR EYES OPEN and don't watch your coil but EYEBALL in the general area you're searching, you can sometimes SEE small gold chains or rings. And to top it all off, a SNIPER coil increases the odds-OK, guys, I'll try not to get carried away on the sniper coil again.
