Thanks,
I have an old church site located. It was built in 1900. It is now a field. I purchased a White's DFX . What settings can anyone reccomend for hunting on this type of ground? Also, is this machine any good for prospecting?
This should be a very productive site. However, you are new and have a highly advanced DFX. This can be a little overwhelming. I will warn you this part first. Square nails, as used in early 1900 construction will give a good coin signal. So be prepared to dig alot of nails.
Second, what coils to you have? The standard 950 is good, but if there is alot of trash, try the EXcelerator 4.5x7. It's a DD coil and goes around trash very good. If you use this coil, be sure to have the V.C.O. turned ON.
As for the program..... being your new here's what I would set it at.
Coins/Jewelry program... than make the following adjustments
Turn Modulation OFF
Turn Tone ID ON
Adjust PreAmp Gain to 3
Turn Ratched Pinpointing OFF
(if using a DD coil Turn V.C.O. ON, if using the stock coil turn V.C.O OFF)
Once you made these adjustments, re-ground balance. This is absolutely necessary any time you adjust the preAmp Gain.
Now adjust the Sensativity UP or DOWN to stableize the threshold.
If it's just way too noisy, turn the Tone ID OFF.
If you are using a small coil, I suggest you try mixed-mode audio (if you do try this, be sure to turn OFF the Tone ID) Mixed-Mode is very had to get used to, but once you learn it, WOW what a difference. And I will agree with what Jimmy Sierra wrote in his book, it's alot to listen too, so turn if OFF every once and a while and get your mind back.
You will need to visit this location several times. Go out to other locations, like parks, to get to understand the sounds a good coin signal makes, and go back to the field. Do this several times over the 12 months. You WILL continue to find coins there.
Last, go the the "FREE STUFF" section in the classifieds and see my post on how to get the book "Understanding the DFX" free from White's. I also hear "Digging Deeper with the DFX" is a must read. However, I have not read it yet, and from what I hear, it is extremely technical, therefore you will want to read Understanding the DFX first and get some field time with your machine before reading the other book.
As time goes by and you understand the detector, make more changes to the settings to fit YOUR preferences. Everyone has thier own special way of how they want to hear and see things, so you just need to find your own special settings.
Good luck and keep us posted on your finds.
