Scuba Diving vs. Snorkeling: Which one is for you?
Expert Guide
Both scuba diving and snorkeling are excellent activities for anyone who enjoys seeing marine life in its natural environment. The main difference between snorkeling and scuba diving is the air supply. Breathing from a scuba tank allows you to stay underwater longer and dive deeper.
If you enjoy snorkeling and are curious about scuba diving, read on! Even if you don’t like snorkeling, you should still keep reading. You don’t have to like one to enjoy the other.
| Feature | Snorkeling | Scuba Diving |
|---|---|---|
| Air Supply | Surface tube | Tank (SCUBA) |
| Depth | 3-4m (10-13 ft) | 5m – 40m (15-130 ft) |
| Training | 15-30 min | 30 min (Try) / 2-3 Days |
Scuba divers carry tanks on their backs (or alongside their bodies) and draw air from the tank via a mouthpiece attached to a hose. Snorkelers, by contrast, breathe air from the surface through a tube. The word ‘scuba’ is actually an acronym: SCUBA stands for Self-Contained Underwater Breathing Apparatus, a term coined by Dr. Christian J. Lambertsen.
Scuba divers wear a lot more equipment than snorkelers. The breathing apparatus is called a regulator. Fun fact: the Star Wars production team used a scuba regulator to create Darth Vader’s creepy, ominous breathing! Divers also need a buoyancy control device (BCD), usually an inflatable vest. Scuba fins are specifically designed to move divers and their heavy equipment through the water with minimal effort.
The average snorkeler can swim down 3-4 meters (10-13 feet). By comparison, experienced divers can explore down to 40 meters (130 feet). During your Try Scuba Diving or SSI certification course, your dives will typically be between 5 and 18 meters (15-60 feet).
Because you aren’t limited by your breath, you can explore shipwrecks, caverns, and even the underwater world at night. Also, because there are fewer divers compared to snorkelers, you have more personal space—no more accidentally bumping into other people’s fins while trying to see a fish.
Snorkeling is mastered in minutes. Scuba requires either a 30-minute briefing for a Discover Scuba session or 2-3 days of training for the Open Water certification.
Is scuba diving scary? Most find it incredibly peaceful. Once you take your first breath underwater and realize how easy it is, the anxiety disappears. Our professional SSI instructors are with you every step of the way.
What is the minimum age? Scuba diving usually starts at age 8-10. Snorkeling is perfect for anyone aged 7 and up who is comfortable in the water!
