Diving equipment is the guarantee of diving safety for divers. Good-looking, fashionable and technological are all based on safety, reliability and comfort. Diving equipment can be prepared by yourself or rented on various islands. Now let's take a look at what equipment to prepare for diving.


Diving Mask & Snorkel

Diving mask (or divemask/scubamask) allows you to see the breathtaking surroundings clearly under the water. The three elements of best choice are comfort, good vision, and anti-fogging. The masks should be in good quality and the frame should be suitable for your face shape.

As for snorkels, not every diver will need one. However, it's normally suggested for beginners to carry one, while more experienced divers will see it as optional. This breathing tube comes in handy when you're swimming facedown on the surface. In addition, snorkels also help to save the air in your tank.

Diveskin & Wetsuits

Diveskin is suitable for wearing in tropical waters. It can be worn on the inside of the wetsuits, which is convenient for taking off the wetsuits and also protecting your skin.

The thickness of wetsuits is between 1-5mm, suitable for the environment with water temperature of 10-20 degrees. Wetsuits should fit your body (generally tighter is appropriate), provide less positive buoyancy and have good waterproof performance.


Fins are generally matched with diving boots. They give you control over your movement and allow you to propel yourself through the water with speed and agility. Fins are divided into open heel and full-foot. Within those two categories it find two more variants - blade or split.

Open heel fins are commonly used in cold water. Full-foot fins completely cover your feet and are normally used in warmer water.

Scuba Tank or Diving Cylinder

A scuba tank or diving cylinder is another vital compoment of your diving gear. It stores large volumes of air, allowing you to breathe underwater. Most tanks have a maximum pressure rating of around 2000 to 3500 psi. Generally made of steel or aluminum, scuba tanks come in various styles and sizes. You can either rent them or invest in one if you plan to dive frequently.


The function of the regulator is to convert the high-pressure air in the cylinder into normal-pressure air and then let us breathe. The regulator has the greatest impact on safety in all equipment. It has something called a first stage, which connects to the tank or diving cylinder you wear on your back, and a second stage—the part of the regulator that you put in your mouth. It also has a backup second stage and gauges. When choosing a regulator, the comfort and performance is what you need firstly.

Diving Computer

It is almost listed in the to buy list. It is a diversified multifunctional diving instrument that can check the safety stop time, dive depth, times, too fast speed warning, NOFLY time, historical record, etc. If you connect it to some small equipment, you can also check the residual pressure. Renting a dive computer can cost you more money, so it's often better to just purchase one.


BCD (bouyant control device) also called buoyancy compensator. It has three main functions:
1. allows you to float on the water to rest or swim
2. allows you to adjust your buoyancy when underwater
3. used as a back frame, carrying the entire scuba system on your body.

It's basically a vest or jacket that you wear during your dive to help manage your buoyancy.

Dive Light

Diving flashlight can be used for night dive, cave dive and fill light in daily shooting. It also provide critical light when exploring cracks and crevices. Many dive lights have SOS mode, can be used to transmit signal. It is one of the necessary auxiliary tools for divers.

Depth Gauge, Submersible Pressure Gauge & Compass

A depth gauge displays the current and maximum depth reached during a dive. A submersible pressure gauge (SPG) displays the amount of gas remaining in the scube tank or diving cylinder, which make you know how long you can stay underwater. Divers must develop the habit of constantly checking the SPG. A compass is used to identify the direction underwater. It is very important in diving, especially when there is low visibility.

Other things you may need for diving include diving gloves, diving boots, line wheel, surface Marker Buoy (SMB), diving headgear, pointer, diving camera, diving knife and spare mouthpiece etc.
