I just purchased this for the SAR academy a few months ago. So far this compass is working well for me with the exception that the inclinometer keeps sticking. Several other students are using this compass without this problem so I figure mine is a lemon. Fortunately I bought it at REI so I'm returning it later today in exchange for another MC2.
I wanted the mirror for signaling, for removing debris from my eye, shooting precise azimuths, etc. It's a luxury feature and by no means necessary. If you don't need the mirror, then the Suunto M3 looks really nice.
I read and observed on Youtube some negative reviews of the Americanized Silva compasses. They felt that the quality was lacking compared to the Swedish version. One guy had significant problems with bubbles and felt that his compass was inferior compared to others at high altitude. Many people use them and are happy with them and I haven’t touched one since the ‘80s so take it FWIW.
With my failing eyes, I really appreciate having the magnifying glass on the baseplate. I use this constantly. I like knowing that this is a back-up for my reading glasses.
EDIT: I somehow bypassed the first page and just now realized that much of this has been covered. Sounds like you have this dialed in (pun intended.)
