The most important thing in drift diving is not to stay away from groups and buddies.

Pay special attention when descending or ascending, as the direction of the tide may differ between near the sea surface and near the sea floor.

■Preparation for entry

For groups to gather on the seabed where tides are fast, exhaust BC completely before entry.
Press the oral button of the inflator and inhale BC air. That way, you can completely exhaust BC on the boat.
