Freediving Snorkels: Why the Simplest Design Works Best
A freediving snorkel should be a plain, flexible tube with no valves. Why simple beats ‘dry’ snorkels, how to carry one, and when it leaves your mouth.
The best freediving snorkel is a plain, flexible tube with a soft mouthpiece and nothing else: no purge valve, no dry top, no splash guard. Freedivers use a snorkel only to breathe comfortably face-down at the surface between dives. It comes out of your mouth before you descend, so the clever features built for surface snorkellers just add drag, bulk and things that can go wrong.
What a snorkel is for in freediving
In freediving, the snorkel’s job is small but useful. It lets you float face-down between dives, rest, keep your face in the water and watch your buddy’s dive without lifting your head. A relaxed, neutral neck helps you settle before your next turn.
It isn’t part of the dive itself. Most freedivers let the snorkel drop out of their mouth before the final breath and descend without it. On the way back up, you surface with your airway clear and start breathing straight away, with nothing to clear first.
Why dry tops and purge valves get in the way
The snorkels in tourist shops are designed for someone swimming at the surface for an hour who wants to avoid swallowing splash. A freediver has different problems.
- Drag. A bulky top and a valve chamber catch water on the duck dive, and on the descent if the snorkel is still on your mask strap.
- Trapped air. Dry-top mechanisms close when submerged and hold air, adding a little buoyancy and a wobble you don’t need.
- Things that stick. Float valves can jam with sand or salt, and a valve that closes when you want to breathe is unpleasant at best.
- Noise and leaks. Purge valves gurgle and leak as they age, and the noise is surprisingly irritating during a slow breathe-up.
What to look for in a freediving snorkel
| Feature | Freediving snorkel | Typical snorkelling snorkel |
|---|---|---|
| Tube | Simple J shape, often flexible | Rigid, often with a corrugated hose |
| Top | Open, no guard | Splash guard or dry valve |
| Bottom | No purge valve | Purge valve chamber |
| Mouthpiece | Soft, low-profile silicone | Often stiffer and bulkier |
| Attachment | Detachable clip or keeper | Fixed clip on the mask strap |
A few more details make a difference:
- A mouthpiece you can hold without biting. Clenching your jaw wastes energy, and the tension spreads into your neck, which can make equalisation harder.
- Sensible length and bore. Every breath through a snorkel includes air left in the tube from your last exhale. A very long tube adds to this dead space, and a very narrow one adds resistance. Mainstream freediving snorkels are designed around this, so skip novelty extra-long or skinny tubes.
- A flexible section or a fully soft tube, so it folds out of the way when tucked into a belt or pocket.
- A clip that lets go easily, so you can detach the snorkel in one movement.
Where to keep it: mask strap, belt or pocket
The mask strap is the conventional place, usually on the left side. It works for fun dives and shallow training, but a snorkel dangling by your ear adds drag and can tug at your mask on the way down.
For line training, many freedivers clip the snorkel to their weight belt or neck weight, tuck it into a wetsuit pocket, or simply leave it on the buoy. In depth competitions, athletes generally don’t dive with one at all. Try a couple of options in the pool and pick the one that leaves your head and neck free.
Snorkel in or out during the breathe-up?
Instructors genuinely differ on this, so here are both sides.
Face in the water, breathing through the snorkel. It’s relaxing, your neck stays neutral, and you can watch your buddy below without effort.
Face out of the water, holding the buoy, no snorkel. You avoid breathing through extra tube volume and resistance, there’s no chance of a mouthful of water, and it’s closer to what you’ll do in a competition.
Our view: try both with your instructor and use whichever lets you breathe slowly and calmly. The breathing itself matters far more than the tube. A breathe-up should be relaxed, with an exhale a little longer than the inhale, as described in our breathing exercises for freediving. Fast, deep breathing is hyperventilation whether or not there’s a snorkel in your mouth, and our explainer on why hyperventilating before a breath-hold is dangerous covers what it does to your safety.
Why the snorkel comes out before you dive
On the way down, water fills the tube. If the snorkel is still in your mouth when you surface, your instinct is to blast that water out, and a hard exhale is the last thing you want at the moment your body is short of oxygen. Worse, you may inhale a mouthful of seawater.
So the habit is: snorkel out, final breath, dive. When you surface, keep your face out of the water, start recovery breathing, and let your buddy watch you closely for the next 30 seconds. Competition surface protocols ask divers to clear their faces and signal within seconds of surfacing, and the same habit serves you well in training.
Safety: Let the snorkel drop from your mouth before your final breath, and surface with your airway clear. Your first job on surfacing is recovery breathing with your buddy watching, not clearing a tube. Never dive alone, however shallow the water.
Snorkels in Indian pools and on dive boats
In city pools, you’ll mostly use a snorkel while resting between dynamic lengths, if at all. Some public pools have rules about fins and snorkels in shared lanes, so ask before your first session rather than debating it with a lifeguard mid-set. Our guide to pool training has more on training considerately in busy lanes.
On boats in the Andamans or off Goa, snorkels get stepped on, sat on and left in the sun. Keep yours in a mesh bag with your mask, rinse it in fresh water after every day, and store it out of direct sunlight, which slowly hardens and discolours silicone. Don’t share mouthpieces, and if you rent, ask for a clean one or bring your own.
Choosing your first freediving snorkel
A snorkel is one of the cheapest things you’ll buy, and one of the first: our guide to buying freediving gear in India puts it right after the mask. In the shop, or when the parcel arrives:
- Hold the mouthpiece in your mouth for a minute. Your jaw should feel relaxed, not clamped.
- Bend the tube. It should flex at the bottom or along its length.
- Check there are no valves or guards, or that any guard comes off.
- Test the clip: can you detach the snorkel with one hand while wearing a mask?
- Pick a colour you’ll spot quickly in a pile of other people’s kit.

Frequently asked questions
Should a freediving snorkel have a purge valve?
No. A purge valve is meant to make clearing water easier for snorkellers who swim face-down for long periods. Freedivers rarely need to clear a snorkel, because it comes out of the mouth before the dive. The valve adds bulk, can leak or gurgle, and collects sand. A plain tube is simpler and more reliable.
Can I use a full-face snorkel mask for freediving?
No. Full-face snorkel masks are made for floating at the surface. They hold a large volume of air that you can't equalise on the way down, they don't let you pinch your nose to equalise your ears, and they make it hard to breathe freely or speak quickly when you surface. Use a low-volume mask and a separate simple snorkel.
Which side should a snorkel go on?
By convention, snorkels sit on the left side of the mask strap, because scuba regulators come over the right shoulder. For freediving it matters much less, and many freedivers keep their snorkel on a belt or in a pocket instead. Choose one place and keep it consistent so your hand finds it without thinking.
How long does a silicone snorkel last?
With rinsing and storage out of the sun, a silicone snorkel usually lasts several seasons. The mouthpiece wears out first, especially if you bite it, so check for tears and replace it when the bite tabs thin or split. Sun, heat and being crushed in a packed bag shorten its life more than diving does.
