Equipment

• Hand level, David White Builder's
Determining the horizon
• Laser pointer
Determining the level of distant object and to make sight lines clearer.
• sighting compass, Suunto KB-20
For determining the magnetic azimuth. For calibrating this magnetic azimuth see the calibration page. This compass seems to have a statistical error of 10' and a reading scale interval of 1^o.
Normally this compass should be read by using the two eye method, but if you has an eye condition called heterophoria, one should use the one eye method.
• spectacles without iron!
Even a small bolt can change the reading of the compass. So be aware about glasses and watches with iron.
• two bags with polyethylene/peas pellets
This is a light weight bag for leveling your compass/level/photograph equipment/etc.
• photograph equipment, like Olympus OM 10, 28 - 170 mm
For making pictures and to determine the altitude of the horizon.
• removable chalk
To mark positions
• rope, some 50 m
For determining the free path (can also be done with laser pointer).
• two length tape, 5 m, interval 1 mm
To measure length.
• two torch
To get light in chambers;-)
• four aluminum camping nails
To pin down the rope or other things.
• a clipboard
To have a good writing surface
• maps
They should be at least 1:25000
• paper for detailed photo registration
some columns with info about the photos taken
• literature
You need to bring all literature available on the site, so that you can look up and compare and see if mistakes are made in your measurements or in literature.
• time
You need time and you need to visit the site a few times. Relaxation will bring ideas and a clearer mind.
