    The difference between snorkeling and scuba diving is the level of equipment-assistance. Sometimes, snorkeling is also call skin diving; basically, the diver will use very limited equipment such as a snorkel, mask and fins. They normally dive in shallow water near the shore; the time they dive is the time they could hold their breath. They don't really need to learn and they don't need a license to do so. Scuba means Self Contained Underwater Breathing Apparatuses. The most obvious difference is the air-tank at the back of those divers. They dive into the water by breathing from an air-tank contains compressed air which pressure could be as high as 3000 p.s.i.. They could dive up to 130 ft in terms of safe range for non-mixed gas. Scuba diving need training and almost all dive shops would not rent gear or allowing non-trained person to be engaged in such activity because a license to do so.

    Snorkelling is done around the more shallow part of the sea where people can just float and look at the coral with their heads down. But scuba diving requires a diving licence and scuba divers are to dive right into the sea to look at the coral fishes around the deeper part of the sea (depth depends on the entitlement according to the licence and diver's experience). snorkelling do not require people to be able to swim but scuba diving does.
