Product Review (submitted on January 30, 2010):
This is an excellent compass for motor home satellite dish alignment. It works well, is accurate and easy to use. I like it better than my $180 Suunto Tandem. To align a manual dish you must determine where north is so the reference dial can be set. This compass makes that job easy. Determine what direction the motor home is facing by getting 10 or more feet in front or back of the home and sighting down the edge of the home. Read the heading on the compass and set the adjustable pivoting dial to the same heading. Open the compass all the way and place against the inside wall of the home and north will be shown on the pivoting dial triangle (36 on the dial) Note: Do not read the floating compass dial at this point.
