WARNING: this is a night cache!
Behind enemy
lines...
You have a
mission...
Finding a secret detonator box before
daybreak!
With a task force that can run out of
resources any minute...
It may turn you into
madness!
This cache is only for tough guys. The
expedition is about 12 kilometres through dark woods. It will take
you at least 5 - 6 hours to complete it. The target can only be
found during night.
You need some advanced technology. However,
do not panic, your (simple) digital camera and your GPS will do it
for you! During the expedition you will find out how to use your
digital camera as an infrared device.
You must also have some basic knowledge
about positioning and co-ordinates. You will need to make
"projections" and you must bring a "triangulation" to a good
end.
So, prepare your trip very well and read
this text carefully.
What do you
need?
-Caution: do not depart on this mission on
your own (team of 2-3 persons is OK)!
-Safety: make sure you have a (charged) GSM
with you in case of...
-Light: you need an electric torch (lamp)
with enough spare batteries.
-Equipment: you must absolutely have a
digital camera with you.
-Information: do not forget to bring this
cache description with you.
-Clothes: some parts of the walk are quite
muddy and wet, so put on the right clothing.
-Drinks: 12km in dark woods is quite a
challenge! Take some water/drinks with you.
-Maps: you will need a topographic map of
the environment situated at the north and west of WP1 (e.g. a
print-out of OZI or Mapsource on your GPS).
-Know-how: it is a good idea to practice in
advance: do some projections and perform a triangulation (you can
do this on your GPS or by hand - in that case take pencil, paper
and protractor with you).
-Sight: do not forget your glasses: some
WPs are quite small to read.
-Backup/Help: see below for help when you
can not find a particular waypoint...
Starting your
mission
To find the secret detonator you have to
discover several beacons placed by the enemy. Make sure it is
completely dark! You can only find these beacons during night. You
are looking for devices, "things"...
WP1: is your starting point
N50°16.388 E5°37.943. You will find there a tag pointing to
WP2.
Please respect nature: leave your car
here!!! You would get stuck anyway, so do not even try
it!
WP2: find here the first beacon.
Look about 15cm above ground level. Note that you can NEVER spot a beacon from the path. Put
your lamp off!! It is important to realise that the position
of a beacon is never given accurately. Hence, when you are arriving
at the location, start looking for it in an area with a radius of
up to 40 meters around the given position. Once you found the
beacon you must do 2 things:
-measure its exact location (with your
GPS), as projections and triangulations always starts from the
actual position of the beacon itself,
-read very carefully the tag next to the
beacon!
WP4: will give you 2 angles: the
upper angle is the bearing of WP5 measured at WP4; the
lower angle is the bearing of WP5 measured at WP3.
WP6: this
beacon is invisible in the dark as it is infrared, but its position
is given very accurately and you can use the spoiler
photograph on this page (bottom picture). So, spotting it must be
possible with your torch. Once you found it, use your digital camera and
point it to the tag (from a distance of about 15cm). You will
notice that your camera is sensitive for infrared light! Look at
the display of the camera and count the number of light flashes per
minute:
5 – 10 flashes/min,
go: 827m
183.6°
10 – 20
flashes/min, go:
491m
98.4°
20 – 40
flashes/min, go: 473m
176.4°
40 – 80
flashes/min, go: 738m
150,3°
WP7: is a transparant plastic tag
and invisible in the dark! But its position is given also
accurately. Spot it with your lamp!
WP8: reveals the position of the
detonator box!
We wish you good luck on this Mission to
Madness,
CB
HELP AND BACKUP:
In case one or more WPs should be vandalised you are
stuck!
To continue and get help during night you can call the
number 0471/386637.
Wait for about 10 seconds, an automatic robot voice will
give you coordinates.
Call only when you are really blocked!
It spoils your mission!!
Each call to this number will be logged on the cache
page.
