Hold G beside a crystal, bulb or vent mat to gather it; it is gone from the reef and banks at the ship. Hold the light on an animal or a landmark to log it, or sweep to log everything in a wide cone. Rise beneath the ship and slow down: the clamps take you, bank your cargo and charge you. Sink to launch; the sub warps down to the reef by itself, and rising stops it.
The lamp rides a boom to starboard, so things cast shadows.
Bub is another pilot at work on this reef. His gauge gives range and bearing.
