Tip of the Day 10/22:Puzzle caches —fake coords

Find It Friday is taking a turn for the puzzling the next few weeks. We’ve heard from a lot of cachers that they don’t even try puzzle caches because they just don’t know where to start. We’re here to help,as always! We found a great resource on the Geocaching NSW site and Darren Osborne has agreed to let us share it with you.

Since mid-2008,puzzle caches require the starting,or fake,coordinates to be within about 3 kilometres from the actual geocache. In southern Australia,this equates to roughly ±2′(minutes) east/west and ±1.5′north/south. Typically this will also mean the degrees portion of GZ will be identical to the fake coordinates –unless it is close to a longitude/latitude line,which will narrow down your search for 10- and 15-digit puzzles.

For example,if the fake coordinates are S33 24.509 E151 02.677 and you need to solve AB CD.EFG HIJ KL.MNO,you can reduce this to S33 2D.EFG E151 0L.MNO and that D is 3,4,5 or 6 and L is likely to be 0,1,2,3 or 4.

If the puzzle uses repetition – such as AB BB.ACA – this will help you even further.

Example:

The geocache’s starting coordinates are S 33° 46.800 E 151° 01.000

The puzzle asks use to find the cache with the following:AA° BC.DEF GHG° FG.ACG

We could quickly solve most of this as we know A=3,B=4,G=1,H=5 and F=0.

So now our puzzle have been reduced to this 33° 4C.DE0 151° 01.3C1
