Chemistry comes to geocaching with this trackable Geomedal in an antique silver coloured finish. The front shows an atom with spinning electrons and 3D details. The back has a ridged pattern around the outside ring and a laser engraved plate in the centre that is adhered to the token. It features the chemical formula for Germanium Oxide from the Periodic Table of Elements, which spells GeO. Cutouts in the metal add to the appearance and allow for easy attachment to an object for travel. It is also available with other versions in a set.
