Reservoir Reverse
Please Read:
Unlike many reverse wherigo cartridges, especially of this type, I recommend you PARK and START at the listed coordinates.
The final cache is hidden ON the track from the parking coordinates. You will follow Reservoir Track past BOTH the large reservoir tanks, and then continue on the dirt track once the tarmac ends. The cache is literally hidden ON this track, so do not divert off it, and keep checking your cartridge until you reach a point where the cartridge bearing suddenly changes by 180 degrees behind you rather than infront of you. (this will mean you have just walked under / past the cache!)
The cache is NOT at the posted coordinates
This Wherigo converts your player into a virtual version of the "Reverse Cache Box" which tells you the bearing to the cache, but not the distance.

The cartridge was created by day1976 and is available to download from the wherigo website. day1976's Open Source Reverse Wherigo .
Start up the player, find and load the cartridge. > NewGame > Find a Geocache > Answer > Enter First Code > xxxxx > Answer > Enter Second Code > xxxxx > Answer > The bearing to this Geocache is xxx degrees. This bearing is from where you are standing. It is now up to you how many times you relocate and obtain different bearings so as to triangulate the cache. The ultimate goal would be to find the cache with just one bearing reading, but for most, it would need a minimum of two bearings. Bearings are with respect to True North, so If using an OS map, allowances will have to be made, as Grid North, Magnetic North, and True North are all different!
To begin, you will have to type these two codes into your player when prompted:
jl3e8
x0666
It is suggested that you take the code with you on your journey. It will be needed if it becomes necessary to restart your player for any reason.
Have Fun!
