An adaptation to the world famous Joani designed custom made nano cache. Perfect for your local urban Geocaching experience. A built in magnet makes it easy to hide these cache containers in various settings.

Now with built in speaker and heat sensitive chip. Are you sick of spending hours trying to find these tiny magnetic geocache containers? Well we've decided enough is enough, these little critters are spoiling our fun so we've manufactured these genius nano containers.

Built into the base is a heat sensitive chip so if a fellow geocacher is within 500 yards their body heat will be detected and trigger the audible device to send out a high pitch tone through the speaker on the base. The geocacher can then easily follow the sound directly to the find and move quickly onto the next cache.

Extra log included as well as a gasket to water proof the container as normal.
