When I first saw freedivers in action, I never really understood why they were using snorkels.
After all, freediving is a sport where you venture into the deep unknown, far away from the surface and any available oxygen. When you’re 20, 60 or even 100 feet or more underwater, you’re too far away from the surface to inhale through a snorkel.
So then why do free divers use snorkels? Why bother if you spend most of your time deep underwater?
The main reason freedivers use snorkels is so they can breathe steadily and comfortably from the safety of the surface, while viewing underwater conditions. Such conditions include the marine life, the current, whether their diving buddies need help and so on. In other cases, some freedivers use snorkels to allow for a smoother breathe-up during wavey or rough water conditions.
For safety reasons, a snorkel is often said to be an essential piece of freediving gear.
The good news is that you don’t need a top-of-the-line snorkel. In fact, an expensive snorkel with all sorts of gadgets and safe-guards can actually hurt your freediving ability.
Instead, all you need is a simple, affordable J-tube-shaped snorkel. I recommend the Kraken Aquatics freediving snorkel. Click here to see it on Amazon.
Here’s what to look for in a J-tube freediving snorkel:
(Also a purge valve on your snorkels isn’t needed as a freediver, because the snorkel shouldn’t be kept in your mouth when diving anyway. More on this later)
Also – rigid, inflexible snorkels tend to wobble when you dive due to all the water resistance. If you’re swimming fast enough and your snorkel isn’t flexible; the rigidness will cause the snorkel to smack you in the face while you dive – annoying and very distracting!

You’ll jet through the water like a hydrodynamic torpedo. 😉
Finding a snorkel that fits comfortably in your mouth, yet comes out the water at the right angle can be a real challenge.
Below are some steps to follow for a comfortable snorkel fit:
Lastly, your mouthpiece should feel natural and comfortable. If it feels strange or like it’s forced into your mouth, try changing the angle of your snorkel. If that doesn’t work, you’ll have to try out another snorkel.
Make sure your snorkel tube is a soft, fairly flexible material. If it’s too hard, it’s incredibly annoying as it will wobble against your face when diving and scare off fish.
Now at this point, you may be wondering at what stage you’re actually meant to remove the snorkel from your mouth during your dive…
Should it be done before the breathe-up?
After the breathe-up? Underwater? When you resurface?
Well, in almost all cases you want to remove your snorkel before you dive down underwater.
For those of you who breathe-up through a snorkel – that’s fine; just make sure you spit your snorkel out before descending. In some cases it can be deadly to freedive underwater with a snorkel in your mouth. This is especially true during deep dives. Why? Well, let’s explore the reasons below.
Reason #1:Your tongue is a weak barrier against water.
When you breath-hold dive underwater with a snorkel in your mouth, you typically use your tongue to seal the mouth piece. Your tongue essentially acts as a small barrier stopping the water inside your snorkel running through the mouth piece and into your lungs.
This isn’t very safe. If you were to get distracted by something like a dangerous animal hovering close by or feeling the effects of nitrogen narcosis…you could move or curl your tongue in reaction. And once you move your tongue away from the mouth piece, the flood gates open and water is able to rush straight into your mouth and lungs. This is not something you want to risk 60 feet underwater.
Reason #2: Freediving with a snorkel in your mouth boosts your chances of drowning.
Typically if you blackout or lose consciousness underwater, your body’s natural defense mechanism kicks in to prevent drowning. This defense mechanism shuts your jaw tightly as soon as you lose consciousness, so you don’t inhale water into your lungs.
But if you pass out with a snorkel in your mouth, your jaw will shut tightly around the mouthpiece. And because you’re unconscious, your tongue muscles guarding the end of the mouth piece will slacken. This will cause water to rush straight from the tube and into your lungs.
Reason #3: Resurfacing with a snorkel in your mouth can lead to blackouts.
When you’re resurfacing from a dive, gasping for air, the last thing you want to do is have to clear your snorkel before breathing in. In freediving, every second of oxygen deprivation counts. The mere seconds you spend on the surface trying to clear your snorkel before breathing in, could push you over the edge into blacking out.
It’s best to simply leave the snorkel out of your mouth, so when you resurface, you can breathe through your mouth straight away.
Reason #4: Not suitable for strong currents
Diving in strong currents with a snorkel in your mouth is a bad idea. At best, the extra drag from the current will push and pull your snorkel which is kind of annoying and will slow you down.
At worst; your entire mask and snorkel could be ripped off by the current. When this happens, you could inhale water out of shock and the entire situation becomes dangerous.
If you really must keep your snorkel in your mouth during the dive, at least make sure there are no strong currents.
Some spearos doing short, repetitive, shallow surface dives like to keep their snorkel in their mouth the entire time. That way, if they catch something, they can resurface, clear their snorkel and inhale, all the while keeping an eye on the fish underwater. This is especially useful if you’re wrestling with a tough fish trying to wiggle away off your spear.
