It pays to swing that coil back over the spot you just made a recovery from. Hit the park for a couple of hours this morning as soon as the temp got up to 20 degrees. The coins on the left were concentrated in an area no more that three inches in diameter. I was using a probe so I'd roll one out then swing the coil back over it and bam! It would be another coin come out. Stopped by a tot lot afterwards and picked up a 35' and 50 wheatie alonf with some newer stuff.
