What is quicksand in the marine environment and how does a diver deal with it safely?
The sandy seabed is not stable. Currents move sand and create unexpected situations.
Striking the fins close to a sandy bottom raises a sand cloud that hides everything. Move forward and wait for it to precipitate.
Some areas of the sandy bottom are steep and shifting and may drag the diver deeper than planned.
The sandy bottom is beautiful, but requires greater control of the movement of the fins.
