Day 3 and got silver but....

[Anonymous]

Found a 1948 quarter today, my first silver with the Explorer. I wish I could say it was 12" deep but it was 4" loud and clear. The site was where an old home (location dates to 1880s) was recently razed. It hit the quarter within 5 mins of starting and was fired up about the prospects of more and older silver but.... not another coin in 1.5 hrs of slow hunting. I was getting noumerous very short notes that were in the silver range but they were not repeatable or at least not anything I could even begin to pinpoint. The 2D screen icon would jump around sometimes hitting the upper silver range but I couldn't get a repeatable lock. I left the site thinking there had to be more there and was wondering if thoses short single beeps where good targets. I'll be going back so any suggestions on those ghost signals?

Richard,
Congrats on first Silver,
What you are seeing is most likely iron falsing. Sometimes a single iron target, and more often multiple iron targets under your coil will cause intermitant good signals. Generally iron falsing will cause the target icon to bounce around the screen; it will hit primarily in the upper left corner, but can bounce to upper right (which you hear), and sometimes lower right, (actually about anywhere). If you are using any discrimination try turning it off and run open screen to see where the target icon is bouncing. With discrimination or iron mask on you will hear the detector null and the icon position will not move if the signal bounced to a blacked out area. If you are getting a short good signal then losing it this is probably what is happening. With an open screen you won't get the nulling and will be able to see where the target icon goes each sweep. With iron falsing not only will the target icon jump around, but also the location on the ground where you get the good signal will often move. Eventually you'll start to get the feel for iron falsing.
But... The real problem is when you have a good target mixed in with iron. 95% of the challenge of using the explorer is learning to differentiate between "pure" iron falsing and a good target mixed with iron.
Hope this wasn't too confusing.

Are you using manual or auto sensitivity?

I was using semi-auto.

Hey thanks Chris, I'll give that a try tonight.

thats what I thought, to me it seems to false more in auto.. try switching to manual on those signals

Hi all, I'm still working the old house site. It's very small lot about 30'X60' and I realize now it's covered with iron debis from the home being bulldozed. The lession I learned is this: I bought the explorer for several reasons but one of them was to have one of the most if not the most powerful metal detectors on the market today to go after the "old stuff". With all the deep penatrating power I was try to bust through the top 12" of ground and any trash in the way. I found out it just don't work that way. Power to go deep is also power reading all that trash in the way. I know there is good stuff at this site but I wasn't finding it. So after some help from you guys understanding iron falsing and understanding that the 10.5 coil is covering a large area I put 2 and 2 together and turned down the sensitivity. And 15 mins later out pops a 1943 Merc at 5". The sound was good but the 2D icon was jumping from upper right to upper left in iron mask -10. The key for me was that I could isolate a repeatable high note signal and the target size seemed approprate for a coin. The Explorer was right.
