1 |
Choose a location where a diving point with a maximum water depth of about 10m spreads offshore, and stand at the coast entry point. |
2 |
Hold the compass correctly and aim your body so that the rubber line arrow points offshore. |
3 |
Turn the bezel so that the north of the magnetic needle is between the index marks. |
4 |
After entry and descending, move straight in the direction of the rubber line, being careful not to shift the north of the magnetic needle from between the index marks.
When moving, mark the target in the direction in which you want to proceed and proceed without looking at the compass. |
5 |
If you come to a place where there is a large change in the topography, such as the boundary between the rock and the sand, change the direction and proceed along the boundary.
Memorize the terrain and creatures that mark the place where you changed direction. |
6 |
When the amount of air reaches the first two-thirds, go back the boundary in the opposite direction. |
7 |
When you return to the mark of the place where you changed direction, turn your body so that the south of the magnetic needle is between the index mark. |
8 |
Be careful not to shift the south of the magnetic needle from between the index marks, and move straight toward the rubber line. |
9 |
When the volume of air reaches the first third, let's ascent. |
10 |
Make sure you have returned to your starting point. |
