Here are three situations where DP really helped...
This is a total of the targets I found on a morning hunt yesterday.
A few coins came from my scoured local park, so dif that cool old knife, but most of these coins came from some permission lawns that I walked over on my walk home.
I have been over these lawns a ton, lots of directions, different coils, settings even a couple of detectors.
This time using DP AND the sniper coil most of these targets popped up and most were masked but easily noticed.
My soil is tricky with red clay mineralization, even the black stuff GB's pretty high and there are pieces of iron everywhere which does a lot of masking.
If these lawns were in Kansas I am pretty sure I would have found most of them long ago but here it is much more challenging even on the shallow stuff.
This setup with the small sniper made these signals pretty obvious.
Here is a dime I found in one of those lawns.
The hole I dug was not wide, maybe 3", before I got the three pieces of iron out of this small hole first then the dime.
This iron had to be surrounding the coin, one piece might have bern above it.
I had been over this exact spot before and I can guarantee you that but no matter what settings or coils or detectors I used I missed this dime every time.
This signal was not exactly great, a little jumpy, not exactly what I look for even using DP but there was something in this mixed signal that made me dig it...some repeating high numbers although extremely quick.
I believe the big difference that helped me find this dime this time was using DP tones.
In the afternoon another quick hunt.
This site was a small strip of land that used to have a few old houses but were knocked down.
I have been here many times, found very little but modern clad using multi tones, all metal and low disc and monotone.
A few weeks ago I did find an old wheat in an area that is near the front steps in the front lawn of one of the houses using maxed out thresh in disc but nothing old has ever shown up before or since.
A few hunts after I hit this area with the F70 again and a couple of coils, used different settings and even tried the Red Racer twice with two different coils.
Nada...
This time I tried DP and just ran around this site looking for just one good signal.
I got a huge one in the same area near that other old wheat.
It was high and loud and painted pretty big in the ground like a full smashed can or a big iron piece but moving the coil around the area a couple inches away I seemed to get another with some repeating high numbers and tones.
This was actually kind of classic iron behavior, low when you get the coil over iron but on the outskirts of that iron, even a few inches away, there is usually falsing into the high range.
I thought that was what this was at first but moving the coil around the area I still got some pretty decent repeating high number high tone behavior.
Using the pinpointing feature and looking at the depth number changes as I moved from one spot to the other I noticed there were two targets here although pretty close together both at about 4" deep.
The soil was pretty moist here too due to having some pretty good amount of rain the day before so I believe the conductivity of all targets I dug on these hunts were heightened.
That might have had something to do with me being able to find all these targets but this DP stuff seemed to be working just as well before the rain, also.
I went after the smaller target first and I was actually a little shocked that a coin popped up.
A really dirty crusty cent...I hoped it was an Indian head but it was a wheat when I scrubbed it clean enough to ID it.
Then I went after the big target still expecting a big can but again was surprised when a smaller piece of iron cake up instead.
Pretty thick on one end though, and fairly heavy.
The separation in the pic below is not exactly right...add about one more inch of separation between the two but the moist soil definitely helped bleed the iron signal over to the area of the coin if only in those high perimeter falsing kind.
So far DP seems to be working pretty well for me, as I continue to practice I think I am getting better, sensing more, noticing more.
Now I have at least three good methods I can use to hunt in iron and heavy mineralization.
Like changing coils using all of them at certain sites could just increase my chances of finding the better masked targets.
All three methods work pretty well but when I go back and hit sites again with another I seem to find more.
There might be an overlap here, or it could be in some cases what one method might miss another can find more easily.
Using all three when I have the time I think my chances for success have gotten better.
Still experimenting...not done yet but now I know that DP and the sniper coil seems to be a deadly combination.
