About 30 years ago in Central Maine I turned the wrong way while deer hunting and like to never made it back to the road. Ever since I´ve carried a compass even for day hikes.
The suunto clip on can be a lifesaver, or at least an embarrassment saver. For $23 its worth it and will last a lifetime if not damaged in a fall. Other option is a wrist watch with compass and thermometer and altimeter. I bought a Casio about 20 years ago for $50 or $60 and it still works fine except the glow in the dark button has faded to useless.
My favorite compass is the Suunto M2 with the mirror. I use the compass for orienteering games and the mirror for tick checks every morning and night. I also use a mirror on my smartphone and have even snapped a photo of hard to see place to check on butt chaffing.
Smartphone compass is excellent idea, too when you have a signal and battery is charged. You can pull up the map on screen that shows your surrounding highways and your location, then its easy to get unconfused.
