Fellas,

I highly recommend a Hamilton vertical card compass, easily swung and
never a leak. I also like the planform display. I've given up on the
old style compass, always leaking and not legal to fix or refill
yourself. They're pricey, but once you buy it, you're done messing with
compasses.

Anubody ever had problems with a Hamilton?
