It is to hard on me physically. 3 days is enough. I will try again in the future to dig the rest of the pennies. Getting very tired of the penny sound. Had to change my battery on my Garrett pin pointer and the battery lasts a long time on that pin pointer. I would find an area with a number of signals and leave the pin pointer on and look for the coins. The pennies are from the penny pit. The other coins are from around the basketball court. I am guessing at least another 100 or more pennies left? It was nice to dig some other coins. The rectangle thing is from seaworld. Thanks for looking in and Happy Trails.....Z
