NUMBER READING CHEAT SHEET FOR AN AT PRO

[retire05]

I just ordered an AT Pro and am really looking forward to taking it out. I was wondering if anyone has advice on what is generally at various readings. For example, one person I talked to says that IH Pennies are always showing up at 76. I am pretty new and realize that there is no gospel when it comes to such things, but was wondering if there are some basics that I could start off with. I have researched a lot of comments and most people say it is a great detector to differentiate junk from non-junk and a good one to use in fairly trashy areas. I have an Ace 350 and although it is a good machine I dig tons of junk because either it does not discern good from bad really well or I can't discern it using the machine. Either may be the case. I am standing by eagerly for any advice. Thanks... Brad

I would suggest you hunt in pro mode, zero discrimination and set your iron discrimination to about 25. Start detecting and dig most stable signals with a nice reading in all 4 directions. It will take some time. To speed up your learning curve, build a test garden with multiple items like coins, bottle caps, pull tabs etc.

I've had this list saved on my phone thinking I would use it but really, when I'm out detecting, I never think about it. Just dig it and see what it is. Lol

 

[swagman]

Also it depends on conditions, ground balance , minerals etc I have that VDI list and I find it is more practical to see what readings you get consistently on targets. For instant I know when I get 53 it's Nickel or pull tab, 75 is Zincoln, 81 a memorial, 83 wheat or Indian, 86 a dime or quarter and so on because I get the same readings all the time. Different coils will get different readings too and deeper depths will have lower readings then normal. I have had 2 silver rings come in at 67....you just never really know until you hear it, read it, dig it and see it.

I do dig aluminum and steel because I dig high tones first......that's why old bottle caps get's me fooled a lot, if it sounds good dig it.

Thanks, Chad. I hope you are doing well in Texas. I have a buddy that lives just west of Ft Worth and I know he has had tons of rain, luckily no tornadoes hit there....Brad

 

[Chad1972]

Yeah, it's raining again today here. I'm not hardcore enough to go swingin in the rain.

 

[d2]

Going by the list provided may get your hopes up. I never got a 99 number until 3 days ago. As I am digging I am thinking silver dollar, come to papa. Turns out it was a huge washer. And I was in the vicinity of where I found the 2 seated dimes (which read 80 on my machine) It was still exciting though. The numbers are close but I suspect that they are different on each machine. I depend more on the tone than I do the numbers. I don't trust the numbers yet hence I dig a lot of aluminum and iron...d2

 

[swagman]

Actually I was out on some of my constant readings, Dime tends to be 83 and wheats about 77 (but a smoother tone then a normal penny). I have had 99 a few times and it is always for me big iron, a liberty Standing half dollar comes in at 88 to 92

 

[Diggin-N-Dumps]

The list above is a great guide to start with. Knowing these numbers, you will be able to see how they will defer sometimes. But the numbers above are about 70% right ..I only say this, because there is still times I dig memorial pennies that are reading in the quarter range (usally deep)

One thing I have noticed about deep wheats, is they will jump thru almost ALL the coin VDI numbers...I can predict a wheat about 90% of the time

Good Luck !! That Machine is a great machine!

 

[iamavol]

Thanks for the list. New detectorist here in the San Antonio area and this helps. I run an AT Max...assuming the number should ring up about the same correct?

Yes i do not pay to much attention to numbers either.
