■How to use compass

1

Look at the direction you want to go.

2

Aim the rubber line arrow in the direction you want to go.

3

Make sure the compass is horizont with the ground or water surface and keep it on your chest at the centerline of your body.


4

Turn the bezel with index marks so that the magnetic needle (north) is located between the index marks.

5

Make sure that the magnetic needle does not come off the index mark, and swim straight in the direction of the rubber line to advance in the direction you want to go.


6

If you move while looking at only the compass, you may not be able to proceed in the direction that you want to go due to the tidal current.When moving to the target object,

Do not look only at the compass, but proceed while looking at the next target point (rock, creature, etc.) defined by the compass.


Once you have a target in the direction of travel, such as soft coral, swim without looking at the compass.
