Sinking coins

[mwaynebennett]

While in the Gifford Pincho National Forest a few weeks ago I went MDing in campgrounds. The searched areas were under large Douglas Fir trees that shed needles. It was my observation based upon the dates of the clad coins and pennies I found that the needles bury the coins about 1/10" per year. When MDing in the lawns of parks, it seems that the grass grows up, dies and deposits a layer of mulch which eventually becomes organic soil at about half that rate. So based upon those numbers, coins lost 100 years ago would be found 5" deep in lawns and 10" deep under fir trees.

Are there any MDs that can locate dimes and pennies 10" deep?

Which BH provides the best depth?

I think that I need to buy a 10" coil for my Elite 2200.

yrs ago I found a silver bracelet at 10" using a BH202 with stock 81/2" coil- it rang up as dime.-I have several different types of detectors aFishers F5 and the BH202 are both made by same co ,also use a detector pro wader for beach/water hunting-with all these units I hunt with lo disc and high sens,slow coil swing and check batts often.have hit coins up to a measured 14".learn your machine and it will point ya in the right place to dig.for the best odds of finding great stuff hunt all metal and dig every thing-then ya know for sure.NEVER give up on a target-if it set off the detector dig til its found-ya never know whats in the ground
