REFLECTOR: GRT compass calibration

[Craig and Denise Woolston]

Terry-

  John and I have same setup with GRT plus a BM G3 and whiskey compass.
It's like having three watches, you never really know what time it is, just
an average...

  We did do a cal on the GRT and got within a few degrees of the whiskey
compass at the cardinal headings using the compass rose.  BM and GRT dis
agree here and there but not by 20 degrees.
