Recta Marschkompaß DP 10

Recta DP 10 Box compass, the top model from Recta

The underlying mirror allows very simple sighting with a high accuracy by precision measurement of angles by prism-optical system (precision 1/3 degree). The needles are rotating on a sapphire bearings in antistatic fluid. The DP series feature a Noryl case, highly durable, offering strong protection for the capsule. A Noryl case, highly resistant, offers a strong protection to the capsule. It also features a cm scale, and provides sighting line of 11cm when opened. The DP compasses allows handbearing and mirror sighting. It also has luminous markings and a conversion table on the rear of mirror, the scale is in cm. Durable, compact, and easy to use, they are ideal for any orienteering need.

Information
Metal objects or power-lines in your vicinity can deviate the compass needle. Strong magnetic fields can in some circumstances even reverse the polarity. Therefore, it is important to check your compass periodically. Small bubbles in the liquid are of no importance. They may appear and disappear with changes of temperature and air pressure.

Inclination
The vertical intensity and direction of earth’s magnetic field, the Inclination, influences the horizontal plane of a compass needle according to the latitude where it is used. Due to inclination, compasses must be balanced for several zones in order to keep the needle in a horizontal position.

Declination
Magnetic lines do not necessary point to geographical North. The angle between these two directions is called the declination It varies locally and over time between one country and another. With certain models, the appropriate correction can be set permanently, with simpler models, this has to be calculated or taken into account on the fixed declination scale.
