New to MXT...have another question

[deepsix]

Thanks for the feedback...'appreciate it!

On another subject...in the local park, I often find readings that turn out to be the brass spinkler watering heads...Since they are anywhere from 3"-5+" deep, I'm assuming that they are part of an older (turned-off) watering system since they can 'sprinkle/spray' if they're buried...I know coins work their way into the ground but as I can't believe that they re-sodded the entire park, I'm wondering why these brass watering heads are 3"-5" deep... AND, more to the point, if they are 3-5" deep because of years of deposition of decomposed leaves/grass etc. that 'built up' the level of ground...if the older coins I'm hunting are therefore several inches deeper than the sprinkler heads...any thoughts/experience similar??

There has been a lot of discussion over the years on that subject and I don't think there is a definitive answer. My best guess is a combination of many theories that targets will go deeper in the ground from gravity, freezing/thawing, cracks from dry soil, decomposition, rodents, heavy rains, flood water, erosion, back fill and so on. In your case, it sounds like decomposing grass and leaves have built the soil up.
