I went to an old school site being torn down today. School is over 150 years old, and the ground is screaming at me to find stuff.
However after 2 hours of old cans, an old cap gun piece, nails, etc, I came home determined to read more and go back soon.
Im going to re-read everything you posted and the links you gave also.
And I might try to run with the Disc. set at the preset and use a forward trigger selection (in the Relic mode). I read someplace to try that.
I'm a determined bugger.
Steeler,
With a little patience, you should be able to tell a whole can, or other large object from a coin. Here are a few ways:
A can will hit with a much louder volume and a bit broader sound than a coin will for a given depth. Lets say you got a good quarter or half indicator (sometimes even a dollar), but ... the sound is not quite what you usually get from a coin. Pin point it. Again, a coin will pin point with a very compact sound (as you sweep in all metal mode, you'll go from theshold to max volume and back to threshold with very little coil movement) whereas the can will usually be broader. This is sometimes called sizing the target.
If you are still not certain, then, lets say the indicated depth was 3". Now, going back into discriminate mode, raise your coil ~6" and sweep over the target again. If you still get a very healthy sounding hit, it is NOT a coin, it is a larger target buried deeper than the indicated 3".
Now, can slaw is another story.
Oh yeah, I almost forgot. Be aware that when you run in Relic mode with trigger forward, the threshold will null out when you sweep over a target whose VDI is below your disc. setting. It takes a finite amount of time for the threshold sound to come back. If you sweep past a good target that was close to the one that caused the threshold to null, the signal may not be strong enough to punch through ... and
you'll miss it. This is called target masking and can cost you the loss of good finds near junk. When you hear the threshold null, slow down. Investigate the area, sweep from other directions to see if there is anything else around the area.
In the end, it is your decision to put up with the grunts or risk target masking.
