What settings do you use with the AT pro

[KJ&nugget]

I've found the pro coin mode covers 90% of my time.

I think I'll hit most good targets. I have a concern over gold jewelry though. I have tried a couple items for test, nothing I have tried gets me numbers below 45.

Where are you guys marking gold? Will the coin mode block much gold?

Gold is alloyed with many metals and they all give different VDI numbers even between two AT Pro's. White gold ladies rings can ring up in foil range and even high Iron like 38, and these are the ones with the rocks! Coin mode will only get you the larger rings and the silver ones as they are more conductive just like silver coins. It depends on how much fun you want to have or how much digging your willing to do in trashy area or the condition of the grass. In my neck of the woods you can get a huge fine for digging plugs.

I do a lot of relic hunting so I use the zero mode, ground balanced. But, when I go to the beach or when I am out looking for coins and jewelry, I still use the zero mode and discriminate all the iron out (not anything iron, during that type of hunting, I want). When you use the coin mode it notches out some of the mid-tones and, yes you are going to miss some gold. Like Sandman said gold can show up at different VDI numbers. Best to dig anything that is not iron, one can not tell if the signal is a pull tab or a gold ring. Dig everything. Hope this helps.

I can differentiate crown caps and coins now with near 100% I don't have to dig them, but the foil and pull tabs I'm gonna dig. The ATPro DD coil with some operator practice is able to distinguish between the crown caps and coins.

Since they "ding" in the high 80's it's not gold anyway should I pass on one. The only silver ring I found so far had a VDI of a quarter and it was rock solid right to the edge of the coil. Not like a crown cap that starts grunting at the edges

I run pro zero with iron discrimination at 35. This is what Bart recommended when I bought the machine from him. This works well for me in the trashy school ground I am doing. I did find a small silver ring that read 72 vdi and a silver link bracelet that came in at 56 vdi. I hope this helps.

I always start out using Pro Zero all metals in the start than move it up....depends on the area and trash I find....I also pull all pull tabs......believing in the no pains no gains system......You can always hunt an area you hunted before and find some goodies....sweep half the coil length and take your time in coverage....Always remember it's the trill of the hunt that counts.......and enjoy.....

Gold crap covers the gamut of mid range, and gets into the high range and low range too. Jewelry (cheap, expensive, big, or small) shows up anywhere from 40 to 99 on atpro or any decent vlf machine with ID numbers. Page 18 or so of the owner's manual shows a nice graph of this.

Works great if you play the numbers game...The only sure way is to dig........
