Treasure hunting at the beach with your metal detector. A great hobby for any age.
Equipment required is a metal detector that should be able to withstand salt and also go in the water. The second item is a “digger” which is usually a handled-basket made out of aluminum for digging up your treasure finds.
Metal detectors range from the very cheap to the super expensive and you get what you pay for. The more expensive detectors do a much better job of finding buried treasure.
Do your research and reviews before making a purchase of a metal detector so that you will be satisfied with the results.
You never know when luck is on your side and you find something really valuable.
