This is a pattern I have been using in real trashy parks. It works real good for picking up coins. Of course you will lose some jewelry but I only use it where there is a lot of trash like pull tabs, can slaw, etc. It is a killer on nickels. I found all the coins in my previous post using it. If anyone wants a copy I can email it to you in a ptrn file and you can upload it to your Etrac.
