Went down to a local ball field this afternoon with the Simplex+ and the new coil. Ended with $3.51 1 Wheat was the only older coin. It run very quiet and pinpointed better than the stock coil. Id's were also better than the stock coil. Nothing over 5in. deep today. My first impression was very good. Was hunting in Park1 and have the 2.78 update. I've had some problems with rusty bottlecaps with the Simplex with the stock coil but only dug one today. My Simplex will not replace my Equinox but for the price it is a very good detector especially with this coil for me.
