PROFESSIONAL GRADE BOXED PELORUS
Autonautic Instrumental
Watch relative bearings change, predict crossing situations, plot offshore fixes
with a 3 arm protractor, or check your compass by sun or stars. These are some
of the things you can do with a pelorus. Large ships have permanently mounted
peloruses, or some that can be mounted in deck shoes. On a smaller scale,
this portable boxed pelorus will give you many of the same benefits. A compass
adjuster will find this a very nice instrument when calling on an assignment.
The pelorus is stored in its plywood box by resting on two lower gimbals and
folding down the metal sighting vanes. For operational use, the pelorus is raised
to engage two upper gimbals and raising the sighting vanes or installing the sun
shadow vane.
The gimbaled bearing card is 5 inches in diameter, and is marked in one degree
increments. The heading indicator and sighting vanes may be locked independently
of each other. The gimbal is weighted for stability, and overall construction
is of metal and plastic.
The pelorus is quite nice looking in its box which is well finished in natural wood
tones. Apart from its functional attributes, it would be well suited as a marine artifact
in a den or office. Box size is 7.5" square x 5.4" high. SW 4 lbs
