HOW TO USE COMPAS

COMPASS

Compass is a tool to set / find the direction of the wind . Used enumerated by the sailors , pilots , hunters , camp , and other adventurers to move from one place to another . There are two basic types of compass , namely :

1 . Magnetic compass that has been used since mtujuh century ago , in the direction indicated by a magnetic compass needle shaped magnet that leads in the direction of the North Pole under the influence of Earth's magnetic field . The biggest is the magnetic compass used by sailors .

2 . Gyrocompass tools found at the beginning of this century . Not affected by the earth's magnetic .

On the compass that uses a liquid , the liquid used is a mixture of alcohol danair . By using the liquid compass needle will be easy to use , profit is what causes the compass contains more liquid than the compass banyakdipergunakan dry ( dry compass ) .

Part - Part Compass

1 . Dial : The surface where the listed number / letter as at

2 . Visir : Sight the target

3 . Magnifying glass : To see the goals and number on the dial

4 . Hours Indicator : Addressing the location of the Earth's magnetic

5 . Close the Dial : With 2 lines besudut 45 degrees and can be rotated

6 . Hook tool : for rope and can also for hooking thumb

  while doing the shot .

HOW TO USE COMPASS

1 . Place the compass on a flat surface . Once the compass needle does not move anymore , it has a          compass needle pointing to magnetic north . So it's not Arctic . Therefore , compass needles were        attracted by the magnetism of the earth is a few degrees of the Earth's north pole .

2 . Zero goals through Visir ( Sight ) .

3 . If Visir dubious , because less obvious , just straighten the lines contained in the dial towards Visir        cap , align with the target .

4 . Aim at the target point is also called check point .

5 . Behind target ( reading back ) , used when we will return to the point of origin / previous .

The formula behind the target ( Back Azimuth )

1 . Added to 180 degrees when the target bidiknya less than 180 degrees .

2 . Reduce to 180 degrees when the target bidiknya more than 180 degrees .

Examples of goals through :

Suggestions aim at 30 degrees then the goal behind it is : 30 + 180 = 210 degrees

If the target behind the goals bidiknya 200 200-180 = 20 degrees .

Thus the introduction of basic compass may be useful ... and congratulations to guide
