1. Classification of Diving

Diving falls into two categories based on the usage of diving equipment and gears. Diving divided into two categories includes Scuba diving and Freediving.

  • Scuba Diving

Suba Diving requires professional breathing apparatus and diving accessories, including flappers, wetsuits, oxygen masks, weight, gloves, and so on. It includes in-depth sea exploration at a certain depth with proper training. Scuba diving is commonly known as a professional diving style and further divided into wreck, deep, ice, and night diving types.  

  • Freediving

Freediving is a breath-holding activity usually carried out nearby shore or shallow water surfaces without breathing apparatus. However, a snorkeling kit might be used to explore the sea a bit deeper but within the time range to get back to the surface for oxygen. Freediving is usually known as recreational diving style. It is further divided into snorkeling, diving safari, and so on.

2. Two Types of Recreational Freediving

  • Diving Safari

Diving Safari includes in one of the most appealing and popular diving styles. As mentioned with its name, the diving activity is carried out through an especially equipped vessel of a boat or yacht in the middle of the ocean far across the coast.  The dive guide then conducts a session for divers by giving directions all along. The divers do not need breathing gears to perform this diving style; thus, it counts in recreational Freediving.  

It is one of the liveliest diving experiences compared to somersaulting on the coastline only. Usually, the number of dives is limited to four per day; however, it leaves a remarkable impression on people's mind for a lifetime.   

  • Snorkelling

Snorkeling is the most common recreation diving type. It does not require the diver to gain any special physical or swimming training. People from every age group, including kids to adults, can enjoy snorkeling on the coastline in shallow waters without diving gears and heavy accessories. As it does not require oxygen tanks or diving gears to explore the aquatic life, it falls massively in recreational freediving type.

Snorkeling may not require oxygen tanks, but a mask, goggles, tube, and fins are necessary equipment that helps to explore sea life freely and make your diving experience memorable.

3. Seven Types of Professional Scuba Diving

3.1. Drift Diving

This type of scuba diving leads the divers from one point and leaves them on entirely different points with the help of natural water current is known as drift diving. The divers mostly use natural current to drift from the dive site and transported to the other side without using much energy. They are commonly known as drift divers. The natural water current used as the drifting agent is usually tidal or ocean current, and if you are choosing a river, then the natural current course is the lead.

Drift divers tend to relate the drifting sensation as flying high at full speed. It includes one of the extreme professional scuba diving types and is often recommended only for high level experienced scuba divers.

3.2. Night Diving

Right after the sundown, several marine flora and fauna and aquatic creatures come to life and boldly become visible in the water out of hiding in the light. Nightlife at ocean gives you a whole new eye chanting diving experience as you have never witnessed before. Especially if you are on the bioluminescent beach where aquatic organisms, mainly algae/fungi release beautiful glowing lights, it makes you feel like you are in an entirely new world.

Night diving includes exploring the underwater landscape world and mysterious marine life with bright underwater torch or flashlight. A bright underwater flashlight allows the night divers to navigate the sea safely. These torches may also help the divers witness certain types of marine creatures attracted to light or luminous sources.  

Usually, if night divers are guided professionally, the dive guide might also build a light set up on the diving site to help them navigate easily.      

3.3. Deep Diving

Deep diving starts when the diver swims in the ocean at a depth of more than 18 meters. Usually, deep-diving excursions are limited to 30 meters or a maximum of 40 meters below the surface because of diver’s decompression sickness. Deep diving is mostly reserved for exploring the extreme environments, ancient objects searching, shipwrecks, or marine creatures that live on a fabulous sea surface.

Deep diving requires a lot of planning and emergency ascend set up as if the diver falls into decompression sickness, and other divers may climb him by the rate of 18m per minute towards sea surface. Deep diving includes several dangers for the divers as deeper he goes to explore sea life; thus, 40m is the maximum standard limit set for deep diving.

Technical diving requires the divers to use the professional breathing gears, which requires special gas mixtures compared to compressed air for breathing underwater. This type of diving requires the divers to go in more resonant length up to 130 feet appro. 40m or more where the direct access to the natural light or sea surface is nonapparent.
