sary, to achieve the proper focus at various
distances.
MOUNTING ON A TRIPOD
The OTS 4T is tripod mountable and can be mounted on tripods with a 1/4”

pass Scale. To calibrate rotate

tion, as pictured on the left.
NOTE

vice please remember that
the compass will work best
when holding the OTS 4T
parallel to the ground.
