I have always been looking for an excuse to buy a metal detector. Costs range from $79 to many hundreds. Mine was $147. Over the years I have lost arrows in fields. Today my crossbow arrows cost $10 or so per arrow. Finding them was not difficult with the metal detector. I found the head of a golf seven iron too. Maybe you need an excuse to buy one. Amazon delivered mine in a day. Assembly was easy.  

Have Fun!
