Digging the plug is the easy part. The pinpointing takes learning your detector. Practice with a coin on top the ground. Once you can pinpoint with accuracy, you are ready for the plug or the pop out method. With the popout method, you push your probe down till you touch the coin. then you move the probe over to the side of the coin. now you push your probe about 2" lower. next you push your probe over sideways. this pops the coin out. This might work to about 3"down. If lower I would plug. To plug just picture a 6" circle around the coin and push your trowl down all around the coin on the 6" circle. Never plug less than 3" or you will cut the grass roots! Lever the plug out and place it on a clouth beside the hole. Now check the hole and the plug. Get the coin, replace the plug. That was easy!
