So, you've binged a few treasure-hunting shows and now you're wondering if your own old detector in the garage can find you a pirate chest. One of the first questions that may pop up in your head ...

Why would you want to detect metal? Oh, I don't know … maybe you want to find some gold in the ground. You could dig up ALL the dirt, or you could find the location that has the gold before you dig.

Scanning parks and beaches with one of these can be a unique and fascinating hobby.
