Hello. For those of you who have access to a tiger shark and wouldn't mind helping me out I have a question. .in disc mode (normal mode) with disc on 0 all the way down,will your unit read a Bobby pin consistently? Now if you switch it to salt mode will it read it. Mine is like it is almost rejecting the Bobby pin at 0 disc and my understanding was that it would go down into the iron ranger enough to read it. Thanks. Daniel
