Treasure-hunters' aids are often MAPS, which are four-letter words. MAPS are used to help people find their way around an area, and they can also be used to locate hidden treasures. MAPS can be physical paper MAPS or digital MAPS, such as those found on GPS devices. MAPS can provide a wealth of information, including geographical features, roads, trails, and other points of interest. They can also provide clues to the location of a treasure, such as symbols, landmarks, and other clues.
