There was a break in the rain today, ground was wet, after my errands took advantage of the last few hours before darkness.
Took the PI out again, almost grabbed the VLF. Looking at the amount of time I gad to hunt, didn't want to spent a whole bunch of time digging pennies.
Went to the local school, today would hunt the open field outside of 2nd base, knew targets might be sparse, there's always something out there to find.
I set the PI up just a tad different, dropped the frequency to combat most EMI, then dropped threshold to almost silence with just a few ticks now and then.
Generally the threshold should be heard with a steady slow ticking sound so you don't lose small targets. Didn't have that effect, the PI worked just fine. Deeper targets would still
increase the threshold to let me know something was there. Some targets were way to deep, so I gave up. To my surprise, my first coin was a Loonie, almost gave up on it too.
Way down in the hole I saw a goldish edge, by golly it was a Loonie. The detector gave off a scratchy broken up sound that was surprisingly loud, would have thought it was junk.
It was then decided to dig all those sounds today, a bunch were trash. And a bunch were deeper coins flat and on edge.
What I learned today using the PI, I can almost silent search knocking out more EMI. Surface coins to about 4-5" depending upon size give off a loud clear crisp sound. Deeper coins and those on edge give off a scratchy almost trashy sound, anything deeper again, you'll notice a nice clean sound as the threshold sound slightly increases. Bare in mind I am using a 7" search coil, and not sure of it's full depth potential on coins yet. Finding deeper coins as I use it more and learning the target sounds.........Not sure I'm ready to put the 10.5" search coil on to hunt the school yards...LOL
I did OK today finding clad, hope to get out a few more times before winter finally takes hold.
Pictured below are finds from todays hunting (1st pix) and my previous hunt.
