More Metal Detecting - Less Luck

Went out for a metal detect yesterday up on an old dirt mount covered with trees and bushes..After getting a strong signal from the Ace 250 i started to dig, it said the item was 2 inches deep. Once i dug 2 inches deep the Garrett Ace 250 changed it's mind  and said the item was now 6 inches deep..So i kept on digging but could not locate the target. i wasn't going to stop digging until i found what was there. After digging a big deep hole i was met with a concrete floor! There must of been metal within the concrete. I felt robbed!

So i moved on to another part of the same mound. I soon got more strong signals...I started to dig and was met with the same..Bricks and concrete. After a while i stopped digging up these signals because they were all giving off the same signal sound from the Garrett Ace 250.

I think there must of been a building on this mound many years ago, and i think the concrete and bricks were probably the footings of the house / building.

Until the next time.............
