On the B/C scale it is:
- Main beam length measured on the outside
- Inside Spread
- Tine length starting at the beam
- Then you have 4 mass measurements.
Like F.H said go to their websight so you can actually see where the tape goes.
For in the field though you need to look at comparable features.
For example the deer's ears will be about 16-18" wide when they have them perked up.
Each ear is around 8-9" long
The eyes will give you about a 4-5" circumference measurement
And the deer's nose to antler bases should be anywhere around 10" or so.
You can then use those measurements to field judge a rack with a little practice.
