I have owned a number of other compasses and never gave it much thought.  Then with those compasses I cam into an area where I was concerned about my location. I have not checked the declination and struggled somewhat with location.  I finally got out but swore I would research a product that had an adjustable declination and climb indicator. This Suunto is just that compass.  It is well made and has many features for the price.  The declination is adjustable with an attached small screwdriver and the climb indicator is accurate and easy to read.  I highly recommend this compass!
