Compass Suunto KB-20 call buana technosurvey 081908101888 Hand-bearing floating compass The Suunto KB-20 is a hand-bearing floating compass weights only 40 g. It is an ideal instrument for marine, professional and outdoor use. The Suunto KB-20 has an accuracy that is better than 1 degree, graduation is 1° and has reverse scale. Suunto bearing compasses are designed to combine extreme accuracy with ease and speed of operation. The compasses are water resistant. The cards of these compasses are immersed in a special dampening fluid that ensures vibrationless, smooth movement. They are pivoted on polished sapphire tips. The veering assembly is to all intents and purposes subject to no wear and the liquid remains clear and its viscosity low under all conditions. The compasses have been given permanent anti-static treatment. The lens apertures of the Suunto KB-14 and KB-20 types are restricted horizontally by a column, which automatically centers the eye on the optical axis, thus eliminating parallax.
