The Beep Goes On said:Hi STH69 - I'm in Houston so can't be much help, but you may want to try joining some of the local detecting clubs in your area. Otherwise, you can hunt parks, schools, woods, etc., but just make sure you check the rules and make sure it is legal.
Here's a link that may help... http://www.texascouncil.net/

I'd look up PBK and ask him. He can identify anything. If you found that in your yard you'd better get back out there. Good luck.
