CD100A Course Detector
The owner may prefer to use the boat’s own compass. The 
compass must be fully gimbaled and have a flat surface 
underneath to fit the CD100A. Make a hole for a 6 mm screw in 
the bottom of the compass and mount the CD100A as shown in 
Figure 4-44. Secure the 6 mm screw through the center hole of 
the CD100A. Make sure the cable does not prevent the compass 
from moving freely in the gimbals.
