I suspect that cheaper compasses would be just as good at indicating (magnetic) north, but this seems to be the standard item for people who are not absolute beginners.
The whole item being only 85mm x 54mm, the scales marked on the sides are necessarily short, but they might be useful for measuring distances off maps one day - or even something completely different.
It comes with a lanyard, so you can hang it round your neck if you want to.
The needle is not luminous, so does not glow in the dark. That is no criticism as Silva make no claim that it is/does, but for would-be users with night work in mind it might be a reason to choose a different model.
A leaflet explains in very many languages how to use a compass in conjunction with a map. The key point is, find a physical object (that won't move and that will remain in your sight as you move) and travel towards it for a while, then check map and compass again and if necessary change the object towards which you are moving. In thick fog or a blizzard, the only available object may be your companion, standing (at your direction) as far away in the desired direction of travel as you can see.
