I have one that looks like that but a brass colored finish. Appears well made. I admit, I have no idea how to use it for orienteering.
I don't really think orienteering would be a big deal unless you're far from any known landmarks. Most of the stories of people getting really lost didn't have even a basic kit with them. Really goes to show the need for the essentials though. One lady got off trail to pee and died later from starvation 1/2 mile from the trail (they found her with a journal). Sheesh.
Anyway, I think it's worth a 10min vid though. There's a lot more to the advanced stuff but this girl does a good job with the basics.
