Aluminum objects

[mwaynebennett]

I just returned from a local park about 1 mile from my house. I don't think the part is very old... perhaps built in the 1970s. There are thousands of signals there, mostly deep ones, like around 5-7 inches. I did not dig them, only the ones about 3" of less. Those I dug, were 75% of the time coins, 90% pennies. I suppose it is good practice. I estimate there are about 1000 to 2000 such deep signals at the park. When the soil gets wetter, I'll spend more time digging some.

I saw an energy drink can on the ground and passed my coil over it. My Elite 2200 said it was a dollar. It seems that the PT (pull tab) detection circuit only works on small aluminum objects and any aluminum object larger than a PT shows up as a coin. That is a bummer since aluminum stays in the ground forever and does not corrode.

I still have fun and am learning the quirks of the sport.

your old park may have been somthing elese earlyer the deep signals should be checked asp before someone else does older deeper in most cases but not always as youll find all mding seems to have exceptions
