I used the compass for the first time yesterday. I really like not having to do math as I had to when using the compass ruler. The only drawback I have found is the compass covers the scale in a couple places.
Would definately purchase another (I already did get a spare!)
Does what it should

Best survey compass and at a reasonable cost to boot!
