Magnetic compass has glow in the dark principal directional points(N,E,S,W); the compass incorporates an accurate bubble level; basic but effective magnifying lens; analogue thermometer from -20 degrees Celsius to 50 degrees Celsius with 2 degrees Celsius graduations. All these features fit in a 8 centimeters(3 inches)clear plastic ruler.
Pros: Phosphorescent N, E,S,W compass points; accurate bubble level; accurate analogue thermometer; ruler in centimeters and inches; magnifying lens.
Cons: No declination adjustment(only because it's a small ruler which cannot fit any more features)...
Would recommend: Yes
