The scuba divers are required to carry a self contained breathing set that will allow them to remain under water for a long time. Sometimes the diver swims underwater by attaching fins to his feet.
The diver can even choose to move around with the aid of the diver propulsion vehicle. Scuba diving can be done both as a fun and recreational activity and there are professional scuba divers too.
It is always recommended that the norms of diving are learned and followed accordingly while engaging in this adventure sport. Scuba diving in Singapore is a popular adventure sport and there are many scuba diving sites in Singapore too.
