This Stanley London® Prismatic Compass is a fully functional Prismatic Surveying Compass and yields reasonably accurate results.  It comes with an aluminum tripod and canvas cases.  The design of the Prismatic Compass allows the user to simultaneously view the object being sighted and its magnetic heading with approximately 1/2 degree resolution.  The compass case and lid is solid brass with a black powder coating.  "Stanley London," is stamped on the large brass lid and can be removed to reveal the low-inertia aluminum compass dial.  The prism can be flipped up for use as a front sight and concurrent view of the compass heading.  A small cover can be swung into place to protect the prism.  There are also two colored filters that can be placed in the optical path of the measurement to reduce glare.  Mirror image stamped degree markings are found on the compass rose so that the compass heading reads properly when viewed though the prism.  When taking a heading measurement, the magnetic heading appears clearly under the object being sighted.  Two adjustment screws allow the height of the prism to be precisely set for proper focus.  For easier reading, the user can press a small plunger button near the rear sight that locks the compass card.  When the compass is being transported, the compass has a needle lift mechanism to protect the agate compass jeweled bearing.  The rear sight is machined aluminum and has a replaceable thread and a hinged mirror that can also be raised or lowered.  The compass can be threaded onto the lightweight surveyor's tripod with a ball and socket head using standard 3/4 inch x 24 threads.
The compass measures 4 3/8 inches (11.1 cm) in diameter, 1 1/2 inches (3.8 cm) thick, and weighs one pound, 3 ounces (539 grams).  Mounted on its tripod, the height of the compass can be adjusted from a minimum height of 12 1/2 inches (31.7 cm) tall to a maximum height of 21 inches (53.3 cm) tall.  This compass is accurate with a resolution of approximately 1/2 a degree.  Both the compass and tripod come with canvas cases.  The compass case has a Velcro closure and the tripod case has a draw string.
The Stanley London Brass Fully Functional Prismatic Surveying Compass on Aluminum Tripod with Canvas Cases is offered at only $105.  We also offer a Polished Brass Prismatic Compass on a Brass Desk Stand.
