Free diving center in Nosy be
to free diving, making skills on reefs from 2 to 23m, is the best way to reduce the air consumption in scuba
diving. Free diving is showing the diver all the useless moves he's doing, which are consuming air and making the dive shorter.
Once in Free diving, the diver is breathing on surface, and when he's
going down, he doesn't have any other solution to get more air.
The only air he can use is in his lungs. If he wants to stay longer, he has to remove all the useless
moves, make only efficient ones, to save some air.
Not breathing with a scuba gear means no producing bubbles. Then, when practicing free diving, the free diver is going from the surface
to the bottom, and reverse. Such a vertical move is very unusual in the water and is attracting the fishes and other animals which are coming closer to see the free diver.
Ampasindava bay is quite always calm. It's protected from the winds
from the south, east by the mountains of the mainland. the water
is flat in the morning, then a see breeze is increasing from noon
or 1pm, making some waves.
Visibility is often good, from 15 to 30m on the plateau, from 20
to 40m on the continental shelf. Visibility decreases during the
rain season, becauses of the deforestation on the main land. The
rain is taking cubic meters of mud in the rivers which are carrying
this in the bays, spreading this red water with the alternative
current of the tides.
