Beach and Water

Many treasures are hidden underwater and you need to use waterproof metal detector with a sharp scoop with you to get those hidden treasures. The chances are bigger if you try to find jewelry at older beaches. In my point of view, most lost treasures are in the water not on dry land. So underwater metal detector is a must for every hobby treasure hunter.

Gold Prospecting

It is smart to buy a metal detector specially designed for locating small gold nuggets. The general purpose detectors are used for big size nugget. But there are fewer and fewer big nuggets for us to look for. So it is wise to focus on the left small nuggets. These specialty metal detectors are expensive and sure you will get what you pay for.
