These are some 3D printed and micro geocaches. Basically this is a international hobby that uses a GPS (Global Positioning System using satellites) to find small (1cm) to large (ammunition box) geocaches. It is great to get children out into the outdoors, get fresh air and exercise and get to know more about the locations you see. Observation skills are enhanced and a respect for nature is cultured. Information can be found at https://www.geocaching.com/play and we have been happy using Garmin.
