This metal detector is simple to use and makes time spent down at the river fun. It comes with directions but it is easier to understand how to use by watching the video on Amazon that was done. Open the end of the metal detector - reef on it, it's in there really securely and I didn't get it open at first because I thought I would break it. Pop in the battery according to the directions and replace the end. Follow the instructional video on Amazon on the listing for purchasing the metal detector and ready, set, go! I had a ball finding everything metal in my home office before taking it outside. This is my new favorite "toy" :-)
