This protractor was designed by us to specifically to meet the requirements of the Swedish Artillery. It has the less common “Reverse Reading” protractor scale, and with calibrations in both Kilometres and Nautical Miles it is useful for all involved in the littoral environment.

These protractors are digitally printed on the underside of 1.5mm thick plastic to avoid parallax error. They are then laminated with 15 micron Tedlar® to ensure the image is totally waterproof, scratch resistant, and UV stable for many years. They are then laser cut to an accuracy of +/- 0.25 mm.
