If you have been metal detecting without a handheld pin-pointer, you probably have a pretty good grasp of what frustration feels like. Trying to find a dirt encrusted coin that is the same color as the dirt in your plug, can be a maddening experience for rookies and veterans alike.
Dig a plug - sweep the coil - dig some more - sweep some more - dig even more - sweep even more. Rinse-and-repeat until you are ready to wrap your detector around a tree.
It does not take a genius to realize that the faster you recover a target, the more treasure you are putting in your pouch. It would probably be a safe bet to say using a pinpointer can decrease target recovery time by a factor of 3 to 4.
Good thing for you, as there is a brand new pinpointer in town ready to cut those recovery times down dramatically.
