A dive mask is an essential piece of scuba diving equipment that allows divers to see clearly underwater.
It creates an air space in front of the eyes, enabling the eyes to focus properly and providing a clear view of the underwater environment.
The primary purpose of a dive mask is to provide clear vision while keeping water away from the eyes and nose.
-Tempered glass lenses for safety and clarity
-Comfortable silicone skirt that creates a watertight seal
-Adjustable strap for a secure fit
-Low internal volume for easy clearing
-Nose pocket to allow for equalization
Single lens masks have one large lens covering both eyes.
They give you a wider, unobstructed field of view and are popular among underwater photographers and videographers.
Dual lens masks have separate lenses for each eye.
They can be made with a lower internal volume, making them easier to clear and equalize.
Frameless masks have the skirt material directly bonded to the lens, creating a sleek, lightweight design.
They're popular for their low profile and reduced buoyancy.
Framed masks have a rigid frame supporting the lenses and skirt.
They tend to be more durable and often allow for lens replacement.
Full-face masks cover the entire face, including the mouth, and integrate with the breathing apparatus.
They provide a wider field of vision, allow for underwater communication, and can be more comfortable in cold water.
They're commonly used by professional and technical divers but are becoming increasingly popular among recreational divers as well.
Fit and Comfort
A well-fitting mask should create a watertight seal around your face without causing pressure points.
To test the fit, place the mask on your face without using the strap, inhale slightly through your nose, and see if the mask stays in place.
This indicates a good seal. Try on different masks to find one that fits your facial contours best.
The mask should stay in place on your face without the strap.
Lens Material and Field of Vision
The lens material significantly impacts your underwater vision.
Tempered glass is the preferred choice for scuba masks due to its durability and resistance to shattering under pressure.
It also provides clear, distortion-free vision.
The field of vision is another critical aspect.
Single-lens masks offer a wide, uninterrupted view, while dual-lens masks can provide a closer fit and are often compatible with prescription lenses.
Some masks have side windows to enhance peripheral vision, which can be beneficial for divers who prefer an open feel.
Durable, resists shattering, and provides clear vision
Single-lens masks provide a wider field of vision. Side windows allow better peripheral vision.
Skirt Material and Opacity
The skirt of the mask, which creates the seal against your face, is typically made from silicone.
High-quality silicone skirts are soft, flexible, and durable, providing a comfortable and secure seal.
Clear silicone skirts allow more light in, which can be preferable for beginners, while opaque skirts can reduce glare and are often favored by underwater photographers.

Reduces glare
Strap and Adjustment Mechanisms
Look for masks with easily adjustable buckles that allow for quick and precise strap adjustments.
Some masks come with neoprene straps, which are more comfortable for those with long hair, as they reduce the likelihood of hair tangling.
Silicone straps, on the other hand, are durable and provide a secure fit.
The ability to easily adjust the strap ensures that the mask remains in place during your dive, contributing to overall comfort and safety.
Reduces snagging and tangling of long hair
Durable and more secure
A snorkel is a breathing tube that allows you to breathe at the surface while keeping your face submerged in the water.
While it's not used that much in scuba diving, it's helpful when you need to swim at the surface without using up air in your cylinder.
Classic J-Style Snorkel
The classic J-style snorkel is the simplest and most traditional type.
It consists of a basic, rigid tube with a mouthpiece at one end.
It's often bent into a J shape to fit around your head.
-Simple design and easy to use
-Cost-effective and durable
-Suitable for both snorkeling and scuba diving
-Requires manual clearing of water if submerged
-Less comfortable due to its rigid structure
Semi-Dry Snorkel
A semi-dry snorkel is designed to reduce the amount of water that enters the tube while snorkeling.
It has a splash guard at the top and a purge valve at the bottom so you can clear any water that gets into the snorkel by blowing into the mouthpiece.
-Splash guard helps prevent water from entering
-Purge valve allows easy clearing
-Flexible sections more comfortable than classic snorkels
-Water can still enter when fully submerged
-Slightly more complex and expensive than classic snorkels
Dry Snorkel
A dry snorkel is designed to keep water out of the tube entirely, even when submerged.
Dry snorkels have a float valve mechanism at the top that seals the tube when underwater.
-Prevents water from entering the tube
-Ideal for beginners
-Allows for brief dives without the need to clear the snorkel upon resurfacing
-Float valve can occasionally become clogged
-More buoyant, which can increase drag underwater
-More expensive
