Descent

■Descent

After you and your buddy confirm OK and are comfortable at the surface, begin your descent using the descent line or anchor line.

Stay close and maintain visual contact with your buddy during the descent.

In strong current, use the current line or tag line to reach the descent line.

When moving along a tag line, do not go between the boat and the tag line.
If the boat moves with the waves, you could be pinned between the line and the hull, which can cause serious injury.
Use extra caution.

Tag line caution
Be careful with tag lines

If you are using an anchor line instead of a descent line at the surface, the same rule applies: do not position yourself between the boat and the anchor line.

The boat may move significantly in waves—especially near the bow. Avoid contact with the hull to prevent injury.

Avoid the bow/hull

If the anchor breaks free from the bottom, it may surge and swing beneath the tensioned anchor line.

Do not remain under the anchor line near the bottom.

Anchor hazard

Once on the bottom, buddies confirm OK again and then check the surrounding area before continuing the dive.
