Whats better than silver..........?

More gold!
Tried a few different spots today, skunked at the first 2 so we headed out of town to an old favorite park on the banks of a river. There is a swimming hole at the river, and here we have previously dug a couple of silver rings, a few pennys and plenty of old decimal. Instinct said to try it again as we had ignored jumpy pull tab type signals here in the past, and with the gold rings we have found of late coming into that catorgory............who knows. A couple of old decimal coin spills later, got a jumpy 58-61 on the F4, dug it thinking it was a beaver tail and out popped this nice little 3g,  9ct gold and saphire ring. WOO HOO!

Of course Carol had it on her little finger as quick as a flash!

 I think I am now more tuned in to when to dig what might be gold. For those using the F4, or any other Fisher machine here is my experience for what its worth.
Below 20.......Iron based
Below 30.......Junk
30-40............Pull tab (varing soil conditions will change the reading along with depth, orientation etc)
40-55............Copper nickel (mostly old decimal coins)
55-61............Possibly GOLD! DIG! DIG! DIG!!!!!!
60-70............Bouncy signal that drops off below 40 at the edge, Beaver tail pull tabs
60-62............$1 & $2 coins (also anything aluminium!)
63-68............Aluminium screw caps such as from V or wine bottles
70-80............Copper coins, 1/2 pennys at the lower end of the scale, pennys have a much larger profile than 1 or 2c pieces, small silver coins and of course flattened ali cans, but they have such a large profile you can tell what they are, unless of course it turnes out to be a silver bangle!
80-100...........Difficult range to interpret, all higher conductivity metal is here, larger silver coins, medals, bangles, etc along with bottle caps, large rusted iron horseshoes and other larger iron based stuff. Usually if its deeper than a few inches and has a small profile I'll dig it.
Having said all that, things like the rings from beaver tails, mowered canslaw and die cast metal pieces will sitll trip you up, just remember that the brain in the machine has to work in conjunction with the brain of the operator. Simple rule I now follow...........If you are in anyway unsure dig it! Cheers and HH everyone.
