Metal detectors work by generating an electromagnetic field. When metal objects come into contact with this field, they create a current that is picked up by a receiver coil and sent to the detector's control unit. People often use them to uncover hazardous or valuable materials on private property, and they can sometimes be used in public spaces. You will want to look at local laws and regulations before taking your metal detector to a public area.
If you plan on walking long distances with your new metal detector, consider wearing a fitness tracker to get feedback on your activity levels, heart rate and more. You might also use a portable outdoor GPS for navigation purposes.
Additionally, if you are interested in using your metal detector for exploration and discovery, you might enjoy other adventurous devices as well. For example, a drone can map out areas from above, and if you take your equipment into the field, you could use portable solar power to keep it charged. With the right tools and preparation, metal detecting can become a fun, active and rewarding way to explore the outdoors and uncover hidden treasures.
