Benefits of Utilizing a Metal Detector
Bullets arent always on the ground. Perhaps a shot has become embedded in a tree, making it almost impossible to spot by eye. A metal detector will show you where it is.
How about a hypodermic needle in the leaves? Its not safe to be pawing around for it. Let your detector pin point it for you and stay safe.
Lets say you are searching for a handgun or knife or some other weapon in a house hidden in the walls or under the floor. You can actually program some detectors to reject common things like sheetrock nails, screws, and even armored cable, letting you find what you are looking for. A few years ago this would not have been possible, but with the technological advancements available today, your detector will help you in more situations than you can imagine.
Think about working cold cases, where evidence has been buried either by years of leaf fall and erosion, or by human hands. Could you locate something several inches or several feet in the ground with your eyes? Using a metal detector you can.
In an extreme example of a cold-case investigation, a team revisited the site of the 1876 Battle of the Little Bighorn (a.k.a. Custers Last Stand) shortly after a range fire in the area. Using quality detectors and experienced operators, they were able to recover countless cartridge cases and bullets. The advancement of todays forensics allowed this team to actually track the movement of various rifles across the battlefield. We probably will not work a cold case quite that old, but it is important to know just how much you can accomplish with this technology.
