I know that sound crazy but it does work Last spring I was searching for some graves and this Gentleman was helping me using the coat hanger you can tell if it is male or female it is the way you are holding them if it is a female they do not turn for a male they cross Now it is the way you cut the hanger you have one for each hand we tried it all day and several people have tried it it will also locate lost graves Take a heavy coat hanger cut the hanger part off and straighten the rest to a L shape Make two hold one in each hand test on one you know male or female and see what happens If any one lives in the Paris Area I have a pair will be happy to show them how it works Sue
