MOB Geocaches aim to gather certain number of people at specific place and ask them to open the same URL with their mobile devices. As soon as the system detects the required number of connected devices, it will display the final geocache coordinates and an optional hint.
If you want to discover coordinates of an existing MOB geocache, use the URL provided in the geocache listing or search for the desired page with its GC code.
Firstly, you need to create your geocache listing in order to obtain your GC code. Do not publish your cache yet. Fill in the form to set up your MOB.
