Francis Barker Surveyors and
Artillery Prismatic Compass
$1,340.00
This Francis Barker Surveyors and Artillery Prismatic Compass is the best Prismatic Compass available, and yields extremely accurate results.
This famous compass has been proven over many years in all world regions in surveying, artillery, satellite positioning, and compass swinging.
The design of the Prismatic Compass allows the user to simultaneously view the object being sighted and its magnetic heading with amazing 1/4 degree accuracy.
This extremely high accuracy is owed to the precision design, high quality solid aluminum, brass and glass construction,
and the large 4 1/2 inch (11.5 cm) diameter induction-damped compass card.
The prism can be flipped up for use as a front sight, and at the same time view the compass heading.
There are two colored filters that can be placed in the optical path of the measurement to reduce glare.
A small cover that can be swung into place to protect the prism when not in use.
The degree markings on the compass rose are stamped mirror image so the heading reads properly when viewed through the prism.
When taking a heading measurement, the magnetic heading appears clearly under the object being sighted.
Two height of the prism to be precisely set for proper focus.
The compass has a needle lift mechanism to protect the precision sapphire jeweled bearing when being transported.
Simply folding down the sight enables the needle lift mechanism.
The rear sight has a hinged mirror that can also be raised or lowered.
The compass can be threaded onto a standard surveyor's tripod with a ball and socket head using standard 0.650 inch x 20 threads.
The compass measures 4 1/2 inches (11.4 cm) in diameter, 1 7/8 inches (4.8 cm) thick, and weighs one pound, 4.4 ounces (578 grams).
This compass is highly accurate to ± 15 arcminutes (± 0.25 degrees) with 1/2 degree graduations.
The entire compass folds flat for easy storage with a metal protective lid, and the padded case for the compass has a Velcro closure and neck strap.
The Francis Barker Surveyors and Artillery Prismatic Compass sells for $1,340.00.
We also offer the affordable Stanley London Brass Fully Functional Prismatic Surveying Compass with Tripod,
three models of Francis Barker Handheld Military Prismatic Compasses,
and a Polished Brass Prismatic Compass on a Brass Desk Stand.
