Oops! Sorry to have misled everyone. I really thought that my compass was a Plastimo.

Just checked and it's a SUUNTO - really good for the price. This is it:
Yes Rolf, I've used a Silva in the past but (and this may be your problem) I found the numbers weren't particularly clear!!!!!

Interestingly enough the newer Silva 103P compasses are much more readable than the ones I used to have.
I do like this Suunto though, notice how nice and large the numbers are above?
