I have never had the problem of using the wrong end of my 9020's though because the lanyard attaches closest to you.
Which proves two things:
#1 - Always attach a lanyard to your compass. I've heard some recommend adding a whistle to the same lanyard.
#2 - I never used the 9020 with a lanyard ... which means I'm foolish enough not to follow rule #1.
I've heard of Recta, but have no experience with them. I always assumed that was a non-U.S. trademark. I think Nexus (or similar) is a trademark sometimes used by Silva SE/Brunton, possibly outside the U.S.
On a slightly different topic, I tend to think of button compasses as emergency, last resort, better than no compass at all compasses. You really can't use them for following a bearing other than the basic 8 rose points - at least not very easily, and they don't play at all well orienteering with maps.
I'm a person who thinks that people who tread outside of familiar suburbia should carry a decent compass, a great map, and a basic GPS w/ extra batteries ... and of course know how to use all three with each other.
