We’ll also explore the disadvantages, ensuring you’re well-informed before diving in. what are you waiting for? let’s dive in.

What do I Need to know about Drysuits?

Drysuits are considered the best option for scuba divers who practice scuba diving at regular manner and other diver living in colder regions. The suits are considered inflatable and have watertight shells that seal around the whole body of the diver in order to protect him from any elements inderwater.

In general, you can easily practice diving with a drysuit after simple training sessions, but for novice divers, this can be intimidating.

Drysuits have high prices when compared to wetsuits and you can find in the market dozens of different designs. In addition to that, drysuits require a unique set of specific skills to be able to dive with.

How Does a Scuba Drysuit Work?

A drysuit is made from a waterproof material that seems like a dry envelope that covers a diver’s body in order to protect him from getting wet.

From the fact that air transfers heat from the body about 25 times slower than water, in addition to the combination of the drysuit as well as the insulating undergarments, a diver can stay warm for longer periods when compared to wearing a wetsuit.

A drysuit have flexible rubber, silicone, or neoprene to create a watertight seal around both the neck and wrists of the diver in addition to a special waterproof zipper found across the back or chest which allows the diver to wear the suit with ease and seal it around his torso.

A chest valve and shoulder vent enable divers to adjust air levels in the suit to compensate pressure and stay neutrally buoyant.

what are the Risks of Drysuit Diving?

The loss of buoyancy control is one of the main risks of scuba diving in a drysuit. The air in the drysuit will expand while going deeper, and if you don’t properly vent the suit or open the inflator valve, you may have an uncontrolled ascent.

On the other hand, if there isn’t enough air in the suit while descending, it can tighten around your body and cause rashes, bruising, and chafing.

If the neck or wrist seals of the suit are too tight, they can restrict your blood flow causing lightheadedness, difficulty breathing, a carotid sinus reflex, and numbness and loss of dexterity in your hands.

When you maintain and manage the air in your drysuit properly, you can avoid all these incidents, but it is recommended to have the proper training before scuba diving in a drysuit.

5 Disadvantages of Scuba Diving in a Drysuit

Scuba diving in a drysuit offers thermal protection in cold water, but it does come with some drawbacks. Here are the main 5 disadvantages

• Wearing a drysuit doesn’t always mean you be dry .

Sometimes water can enter the suit from the neck seal or wrist seals, because of:

-The increased mobility in the water.

-Damages of the suit.

-Through the zipper if you didn’t closed it properly.

-Through the valves due to improper rinsing, poor maintenance, etc.

• You will become less mobile in the water, as the drysuit will limit your ability to move when comparing to wetsuit mobility.
• Most of the time you will need to add more weight when comparing to a wetsuit, often due to the thickness of the undergarments you will use.
• You will need to replace the neck wrist seals and maintain the zipper regularly. If you didn’t do that in time, you might put yourself in a situation in which you will must cancel the dive, because there is a problem in the drysuit.
• You cannot practice scuba diving in a drysuit without prior training.
