To me the stock coin program is set up to locate various coins in many countries of the world. Now the silver program will also locate gold,silver, platinum, copper etc. as well as rings, jewelery (from my finds) that I have scanned under the coil. With a tighter factory pattern. (less open white area- accept) to accept unwanted targets. So is there any real advantage to using the stock coin program? Unless in another country? Am I missing something here also can more than one mode be on at the same time like the SE and other explorers? alright 3030 pros straighten me out on this.
