The sport takes you into a wonderful new world
This sport takes you into a wonderful new world.It is like a visit to the moon. When you are under the water, it is easy for you to climb big rocks,because you are no longer heavy.
Here ,under the water,everything is blue and green ,during the day,there is much light.when fish swim nearby,you can catch then with your hands.
When you have tanks of air on you back ,you can stay in deep water for a long time ,but you must be careful when you dive in deep water.
To catch fish is one of the most interesting parts of this sport.besides,there are more uses for skin-diving.
