Can you adjust the declination on this compass?

Best Answer

Hi Jenny, this compass doesn't have a permanent adjustable declination, a set screw that you adjust the declination to permanently. It does have a declination scale that you orient the needle to... The red line in the picture is pointing to the declination scale.

Here's the blurb from the manual:

Allow for Declination When Using a Map:
When the paralleling method of declination adjustment with
pre-drawn Magnetic North lines is not available, the
DECLINATION SCALE gives a fast, sure method for compensating
for the difference between True North and Magnetic
North.
1. Take your heading from the map by placing the Base Plate
edge of the compass along your desired line of travel. The
Direction of Travel Arrow points to your destination.
2. Turn the compass Dial so that the Orienting Arrow and
Orienting Lines are parallel to the map side margins. Your
Map Heading can be read at the Index Line on the Dial.
3. Hold the compass level, turn your body until the Compass
Needle aligns with the Orienting Arrow. You are facing your
Map Heading. Now turn yourself slightly until the Needle
offsets against the DECLINATION SCALE to the appropriate
degrees for your area. You now face your Magnetic Heading.
Sight ahead to a landmark and walk to it. Repeat this process
until you reach your destination.
