...I am going to look for that ring that my co-worker's brother in law lost a couple weeks ago...I asked my co-worker tonite if there was any engraving in this ring He said "YES-IT SAYS TITANIUM IN IT""...ALL RIGHTY THEN:I have a question:HOW in the world does a titanium ANYTHING respond on a detector???I didnt even know they made titanium rings...No wonder that guy wants it back-He didnt tell me how much he spent on it;other than it was "a substantial amount"...I guess I will just have to run with very little discrimination;and hope for the best...I will see him again tomorrow night-I am going to ask him if he is sure it is Titanium,and not PLATINUM....
