To find the cache you will need to complete the Reverse Wherigo Cartridge. Don't worry if you have never done one before they are pretty straight forward to play. You will need a wherigo App on your phone first, once you have this from your App store, the Cartridge from -Waldmeister- is available to download here.
The way it works is you are told the distance you are from the cache but not the direction of travel you need to take to find the cache. As you move around looking for the cache you can check your distance from the cache to work out if you are getting closer or further away. This is all explained in more detail in the cartridge.
So to start the reverse whereigo you need to enter a code, which comes in the form of 6 digits on 3 separate lines. To work out the code for this reverse whereigo you must visit the main waypoint of this cache, where you will find a post box.
On the post box, let the fifth digit of the first phone number be G
On the post box, let the fitth digit of the second phone number be E
On the post box, let the post box number (BSXX XXXX) = BSHC BAFD
Substitute the values into the code below and you have the numbers you need for the cartridge:
CADHCF
DDDDBG
AEECAF
The cartridge will ask you for one line of numbers at a time, keep hold of these numbers if the cartridge crashes you will need to put them in again to continue. Once you complete the cartridge you will get a code so that you can create your own reverse wherigo anywhere you like, just make sure you tell Waldmeister about your cache.
Please do not write any hints into your log about how and where you found the cache or post photos that might give the final location away. Thank you.
Please use stealth at the GZ and have fun...
