Flexible Snorkel 1

Best Scuba Diving Snorkel 2021

What kind of Scuba Diving Snorkel should I buy?
Considering of what kind of Water Sport you do there are a few different Snorkels on the Market.

Phantom Aquatics Rapido Snorkel

A snorkel is a flexible tube, generally made from plastic or stiff rubber which connects a snorkeler to the surface air. Snorkels are a snorkelers and diver’s lifeline, allowing them to breath at surface while their face is in the water. So you don’t loose sight of the Beautiful turtle.

There are a couple of important features to know before you buy a Snorkel.

Breathing easily

The right snorkel should let you breathe easily and comfortably for extended periods of time, without making you short of breath or light-headed. Also look after Ergonomic design and conformable wearing it.

Signaling color

A snorkel should always be a complete signaling color or at least the top end should be conspicuously marked so boats and other water crafts can see you easily and move out of your way.

Mouth piece


Made of food grade silicone as they have no odor smell or taste. It should be the right size for you.

Kids need smaller mouth pieces and might need smaller snorkels depending on their age and size.

Some mouth pieces are moldable. Completely personalized mouthpiece, molds to fit teeth.

Be careful when buying a replacement mouthpiece not everyone will fit your snorkel.

Attachment to the Mask strap


There are a few different mechanics to attach a snorkel to a Mask.
Silicone snorkel keeper can easily attach , allows the diving snorkel move up and down to a fit position.

Top left: of the Picture is a plastic clip which attaches to the mask strap.

Top right: is a clip which stays permanently on the mask as you have to remove the mask strap from the mask and fiddle it through then reattach the mask strap on your mask. Then you can put your snorkel through the round hole.

Bottom left: If your Snorkel has a strange form this is a silicone holder you can use.

Bottom right: The most simple Snorkel Holder made out of rubber but effective robust and almost fits any snorkel.

Scuba Diving Snorkel on the left or right side?

Snorkels are always made to wear on your left side. That’s because a divers Regulator second stage comes from the right side so they can’t be mixed up. Modern dry snorkels are ergonomically formed and built so they only can be worn on the left side of your head.

Surface Marker Buoy


If you do a lot of Snorkeling, freediving and spearfishing it’s always a good idea to carry a signaling surface marker buoy with you.

Other watercraft can see you easier as most of your body is submerged in the water while snorkeling the buoy reveals your location from far away.

Scuba Diving Snorkel Length & Diameter size

When your Scuba Diving Snorkel is the length of a garden hose

The snorkel should not exceed 45cm in length and a max diameter of 2cm because of Pendulum respiration. Which means if it is longer than 45cm for example you’d use a 2meter long garden hose, you inhale the same air you just exhaled as you can see in the GIF below the exhaled air is not exchanging to new oxygenated air due to your lungs are not big enough to exchange the air.


You will breath in your exhaled low oxygen air you just exhaled, which you might do a few times and after 15-20 breath you become unconscious due to a lack of oxygen (Hypoxia) and high levels of CO2. You can have symptoms like headaches, insomnia, nausea, but mostly the unconsciousness kicks in before you notice anything else.

When your Scuba Diving Snorkel has the correct length.

However if you buy a proper Snorkel which is shorter than a garden hose as with a max of 45cm and has a Diameter less then 2cm the low oxygen air you exhale gets pushed out and new oxygenated air moves in as you inhale which does then not cause any problems. You can see the GIF below the exhaled (blue) low oxygen air gets pushed out all the way on the top of the snorkel and new (red) oxygenated air moves in.


You breath fresh air with 21% O2

Different kind of Snorkels

There are 4 different kind of snorkels available.

Simple Scuba Diving Snorkel

Westcoast Straighthookers Simple Snorkel

It all started with the Simple Snorkel back in the days where there is not much to it hence the word “Simple”. They are still around today as well as preferred by many including me.

The Simple Snorkel is just a bent tube with a silicone mouth piece at the end so clearing it out, if there is water inside is much harder than on a Snorkel with purge valve.

When water enters the Snorkel it will stay in until you give it a hard blow and all the water sprays out on top of the snorkel.

The snorkel is sometimes not empty after the first blow and that’s where it gets a little hard as you have to slowly breath in and surpass the water still remaining in the snorkel. That only works if there isn’t too much water inside.

If there is still water left in the snorkel at the surface and you can’t bypass it or don’t have enough air to blow a second time obviously you can still remove it from your mouth and empty it that way but you might have lost sight to that beautiful turtle you were just watching.

Simple Scuba Diving Snorkel advantages

  • Robust
  • Durable
  • No issue with pendulum breathing

Dry Scuba Diving Snorkel


Dry Snorkels are a further development from the simple snorkel and have a few advantages such as a purge valve or sometimes a closing mechanism on the top end of the Snorkel.

Dry Snorkels have a one way purge valve on the bottom that opens when you exhale.

If water is inside your snorkel and you do exhale all the water will flow out on the bottom while you exhale.

A simple puff of air is all you need to clear the water through the snorkel’s lower one-way valve. It saves you energy and is especially easy to clear.

Controversial Top dry valve and splash guard


Dry snorkel splash guards automatically closes when submerged, not allowing water to enter the Snorkel. Even with waves crashing over you, the splash-guard will prevent water from entering into the snorkel.

It is controversial because it is a factor for pendulum breathing. The chances are higher that the air inside the tube is not exchanged especially when high waves splash frequently over you or when doing yo yo snorkeling. They might not work properly or not open all the way so your exhale Air doesn’t get exchanged all the way and replaced by fresh oxygenated air and you end up floating unconsciously.

Dry Scuba Diving Snorkel advantages

  • Purge valve
  • Easy to use
  • Ergonomically built

Swim Snorkel

Swimmers Snorkel

Swim Snorkel are a special breed of Snorkels. Because a Swimmer is very quick in the water the snorkel worn on the left side of your head would move constantly backwards and at a certain time it would dip into the water and the swimmer would breath water. Side Snorkels aren’t streamlined and have a high water resistance.

That’s why swim snorkels are designed to wear in front of you at 12 o’clock.

Swim Snorkels have a hydrodynamic design which allows swimmers to swim effortlessly with minimal water resistance. Since they are worn in front they have a different way of attachment as you can see in the picture. Its an adjustable head bracket with a Swim Snorkel strap similar to your Mask strap. Most of them also include a purge valve.

Front mounted snorkels ensure smooth arm rotation and maintain body alignment and improve stroke efficiency.

Swim Snorkels advantages

  • Fast swimming possible without movement of snorkel
  • Ergonomically designed
  • Ensures smooth arm rotation
