This Stanley London® Prismatic Compass is a solid brass reproduction of a large antique Prismatic compass.  The design of the Prismatic Compass allows for the simultaneous viewing of the object being sighted and its magnetic heading.  The large brass lid is stamped "Stanley London," and can be removed to reveal the aluminum compass dial.  The prism can be flipped up for use as a front sight, and at the same time view the compass heading.  A unique feature of this Prismatic Compass is that there are two colored filters that can be placed in the optical path of the measurement to reduce the amount of glare.  A small cover that can be swung into place to protect the prism.  The compass rose degree markings are stamped mirror image so the heading reads properly when viewed through the prism.  When taking a heading measurement, the magnetic heading appears under the object being sighted.  For proper focus, the height of the prism can be precisely set by utilizing the two adjustment screws.  Pressing a small plunger button near the rear sight locks the compass card for easier reading.  The compass has a needle lift mechanism to protect the compass jewel when the compass is being transported.  The rear sight has a replaceable thread and a hinged mirror that can also be raised or lowered.  When the brass stand is removed the compass is threaded for a surveyor's tripod.  The compass measures 4 3/8 inches (11.1 cm) in diameter, 1 1/2 inches (3.8 cm) thick, the compass and stand are 4 1/2 inches (11.4 cm) tall, and weighs one pound, 14 ounces (859 grams).  This compass is well made, beautifully detailed, and polished to a high luster.  Your personalized inscription can be engraved on the top of this compass.
The large Prismatic Compass is offered at only $81.50.  We also offer a similar and more functional Brass Prismatic Surveying Compass on an Aluminum Tripod.
