### Quiz for Surveyors New to the Field

Rob Migliore‎ shared this with us.... let's see how well you do...

I sometimes give an easy quiz to potential field and CAD people during their interview, just to get an understanding of their experience.
I wonder how many of you can answer these questions:
What does it mean to “Buck In” or “Trick In”?
What is the standard temperature correction for a steel tape?
What is “Double Centering”?
What does it mean to “Kick a Leg”?
What does the anagram “SOHCAHTOA” stand for?
How many hundredths of a foot are in an inch?
What is the difference between a Lenker Rod and a Philly Rod?
What is the difference between a PC and a PT?
What does it mean to “Boot the Rod”
What does it mean to “Raise for Red”?
How many feet are in a “Rod”?
What does RTK stand for
What does it mean to “Plunge the Scope”?

Define the following
1. Grantee
2. NAVD
3. Grantor
4. Parrallax
5. Mere Stone
6. Magnetic Declination
7. GPS

• Maybe due to different parts of the country, but I've been surveying for 36 years and I have never heard of "Buck In" or "Trick In". If I'm thinking of the same thing, we call it "Wiggling In". Getting on line between two points.

And I have never heard of "SOHCAHTOA" or a "Mere Stone"
