This is really a quality compass and very easy to use. I like the fact it has a magnetic declination adjustment you can dial in too. It also has an inclinometer, but I confess I have yet to use it for measuring anything. The fact it has a mirror is a big plus as it can also be used as a signal device or checking your face or eyes for injury should you have an accident. The dial and etchings are large enough to read easily and checked against my other compasses, this one seems to be one hundred percent accurate. As with all things, practice with it and you will soon be able to navigate with the best of them!
