Recently, due to the epidemic, many people are unable to travel abroad for summer vacation. As a result, there has been a phenomenon of “retaliatory tourism” in Taiwan. Offshore islands such as Pescadores, Green Island, and Orchid Island among others have seen unexpected swarms of tourists and blooming diving activities.

But do you know? Despite many differentiations, there are only two major diving categories: “dive without respirator” and “dive with respirator”. Now let’s take a look at them and find out your type.


1. Dive without respirator:it literally means that divining without any gear that provides oxygen. Activities in this category include snorkeling and free diving.

Snorkeling
snorkeling is a simple diving activity that requires few prerequisite skills compared to other types of diving. It is an activity of introductory level that allows people to experience oceanic fun by floating on the surface of the water and does not involve deep diving. You only need a snorkel, mask, and fins—basic diving equipment—for this activity. The beauty of the Maldives is now vivid in front of your editor!


Free Diving
Compared to snorkeling, free diving is relatively difficult and requires skills. According to the official definition: “Free diving is the exercise of deep-dive without carrying a cylinder. To dive deep, one needs to hold the breath and relies on abdominal muscle and strength.”, activities involve free diving include fishing, hunting, photography, entertainment, etc. In recent years, free diving has been popular among young people in Taiwan. Preparation does not involve burdensome and various equipment. One can also pose beautifully and selfie in the water! 



2. Dive with respirator:this generally means diving with regulator and oxygen supplied by vessels 

Self-Contained Underwater Breathing Apparatus (SCUBA)
Divers carry their own regulators which convert air pressure in the cylinder to a pressure suitable for human lungs. Open Circuit Scuba and Closed Circuit Rebreather (CCR) belong to this type.

Open Circuit Scuba 
This means that a diver uses a regulator and oxygen in the cylinder to breathe, and directly discharge air into the ocean. Discharging air will create a constant grunting sound—not a sign of hunger. Open scuba is mostly a type of recreational diving.



 
Closed Circuit Rebreather (CCR)
A closed-loop respirator recycles breathing gas and provides fresh air. It does not produce bubbles. (It is said that for military purposes, special agents like 007 use CCR to hide their presence—I would love to give it a try!) (Photo Sources: http://www.cavemexico.com/index.php?show=onas).

Helmet Diving
Most of the Helmet diving is commercial diving. The gear provides air through the transmission tube and can adjust temperature and provides power supply, which allows a prolonged underwater stay. The “underwater walks” in some well-known sites fall into this category. In Taiwan’s Pescadores island, one can enjoy helmet diving without swimming skills. It is a good opportunity to stroll undersea, feed fish, and experience the weightless float. (Photo Sources:https://www.klook.com/zh-TW/activity/7943-helmet-dive-boracay/).
