Main Equipment Recommended by James Mandeville:
Compasses:
Considerations:
- The compass in a Personal Survival Kit should be as good as you can
fit into
the container and should be treated in most cases as a second compass. If you are making a general purpose Personal Survival
Kit it is best to have a global compass (one with a needle balanced for use in both hemispheres).
The Silva Voyager 9020 compass is ideal for this; to make the compass smaller, cut it down to
around 6.5x5 cm as shown in the photo. Shown in the photo is a cut-down compass with new lanyard
holes and the inset shows the original compass.
- "Escape and Evasion" type compasses are only accurate to +/- 5
degrees and they are made to work in one hemisphere but if space is of the
essence, an E&E compass is a good one to choose. The
Silva "SERE" Compass 40H luminous is the best miniature compass to pack in your survival kit
and is available in models for both the northern and southern hemispheres; pack
one of each and make sure you know which is which! Beware of what you are buying
when it comes to miniature compasses, many on the market are little better than
toys so always buy a top-brand compass, never cut costs on this item. The
photo above left shows the Silva 40H E&E compass; see below for more details. Both
the luminous and non-luminous versions of this compass have a lanyard loop (this compass is also sold
without a lanyard loop, so once more, take care what you are buying). All Silva
E&E versions are robust and oil damped.
- Silva also make a version of the 40 model that fits on a wristwatch strap.
If you use this version DO NOT fit it on a strap next to an electric watch as
this will make the compass highly inaccurate.
- Always pack two compasses in your survival kit or one larger and one
miniature compass is a good decision. They take up no room at all
and you need to have a spare. Keep them apart so they do not affect each other.
- Do not pack a compass in a tin box that can become magnetised. Keep it away
from items such as a survival knife, multi-tool, radio equipment, etc., for the same reason. If packed in a magnetised tin, or
kept near a magnetised item, you could permanently damage your compass. Another
reason for using a small aluminium mess tin as described earlier for the
container. Magnetic screening of items such as knives and Multi-tools is a problem and needs careful consideration when you design your Personal
Survival Kit.
James recommends:
SILVA VOYAGER 9020 Global Compass.

Cut it down if necessary to fit your container.)
