The DupleBug™ is a replacement tag for your trackable items. This can be written on with a marker in the place provided and then sent out into the wild instead of your nice shiny geocoin. You can also use these as a replacement tag for those lost or stolen trackables you may have on your profile. The lightweight yet very durable tags will hold up in the wild while traveling from cache to cache. Each one of these will come with a zip tie to make it easy to attach these to most anything.
