Best Compass design

[Ty G]

Not quite bicycle, but useful non-the-less.  I am wanting to really "learn" how to use a compass correctly.  The decent compasses are either flat base plate or sight mirror.  Which would be better for map reading and general getting somewhere and getting out?  Which do you prefer?

Thanks, Ty

I prefer the US military Lensatic Compass.   Simple, rugged, and very accurate.
If you're not familar with the design check out this website.

I do alot of Adenture racing and use only the base plate type compass. It is easy to use either with a map or just finding general direction. Look into Bruntons line.

The Silva Rangers are nice. If it has an inclinometer that can be useful for ski touring to determine slope angle too. Definitely nice to have a mirror.

I teach map and compass classes for [insert large national consumer co-operative that sells outdoor gear and clothing]. I'm also an adventure racer, bikepacker, and backpacker.  I personally only use the $14-15 simple baseplate compasses by Silva or Suunto.  The mirrored sighting compasses are nice and have some great features but a) they are expensive, b) heavy and bulky by comparison, and c) more accurate than you really need for general getting around in the woods.  I would not get a lensatic compass as they are much harder to use in conjunction with a map since you can't see through them and not all have a straight edge to draw bearings, meaning you need multiple pieces of gear.
