Recta DT420 Elite Global System Compass "Designed for worldwide use" What is little known about the compass is that a compass needle dips varying amounts depending on latitude (where in the world you are). The dip of the needle is known as "inclination" and it prevents a normal compass bought in the UK from working properly in the southern hemisphere. Locations such as Australia, South America and much of Africa is affected. That"s why one would need different compasses for different parts of the world. Thankfully, Recta now have the solution. The Recta DT 420 Global System overcomes this problem and will work anywhere in the world - reliably. This compass is the ultimate for active outdoorsman and world travellers.
