■Descent

After confirming that there is no abnormality about the entire group on the water surface, discharge the BC simultaneously for the entire group.

When exhausting with the oral button, the group cannot descend at the same time due to the difference in the capacity of the BC. When exhausting, press the power exhaust button or pull the inflator hose to exhaust the air at a stretch.

Dive following the team leader, being careful not to leave the buddy.

Tidal currents vary in speed and direction at different depths.
If your depth is different from the team leader one, for example because of poor ear removal, you will be separated from the team leader.
In such cases, use the horn to notify the team leader the abnormality.

If the team leader is using a water surface float, descend along the ropes.
Use it as a mark without touching the rope.
If you touch the rope, the rope of the team leader will be pulled strongly, and the team leader will rise from the seabed and will not be able to descend.

There is a team leader on the extension of the rope, so even if you are at a different depth from the team leader because of poor ear removal, you do not have to worry about separating from the team leader.
Relax and descent.
