This surveying compass clinometer DQL-8A is our newest compass which is a technical instrument, housed in an Metallic case. It also has a flip open sighting mirror for more accurate bearing readings, and a long and short arm sighting device on each end of the compass. The instrument can be used to obtains dip and strike readings, accurately due to the inbuilt spirit level. A verticle circle locking mechanism is also on the compass and the needle can also be locked. The surveying compass can also be used to obtain vertical readings, height readings and also be used as a level device. The compass is global and will work in all magnetic zones of the world thanks to the inbuilt declination adjuster which will adjust the needle to local magnetic variations. This compass clinometer is easy to use, robust for use in the field and ideal for professionals in the field of geology, geography, surveying and exploration and comes with a free case which can clip onto a belt. A product technical specification sheet is available upon request. Please email us.

What happens to my compass in the southern hemisphere? For a compass to work properly, the compass needle must be free to rotate and align with the magnetic field. The difference between compasses designed to work in the northern and southern hemispheres is simply the location of the "balance", a weight placed on the needle to ensure it remains in a horizontal plane and hence free to rotate. In the northern hemisphere, the magnetic field dips down into the Earth so the compass needle has a weight on the south end of the needle to keep the needle in the horizontal plane. In the southern hemisphere, the weight needs to be on the north end of the needle. If you did not change the weight, the needle would not rotate freely, and hence would not work properly.
