So how exactly does all this happen? Basically, water that leaks inside the snorkel tube will collect at the bottom, where there is a little valve. With a light exhale, there is enough force for the water to just drain down through the valve instead of having to blow it back up through the tube with a huge gust of air.
Should I get a snorkel with a purge valve? The choice is completely up to you, however we will let you know this. At the same time, fear of water getting into your snorkel is a huge fear of wannabe or new snorkellers, and purge valves can do a lot to help ease and calm these worries. The answer is: too many! Traditional snorkel masks can be uncomfortable and scary for many people, so the beauty of snorkelling goes undiscovered and unexperienced.
Whether it's breathing difficulties, choking on sea water, or foggy goggles, there's a lot that prevents people from enjoying the wonderful sport of snorkelling. And that thought makes us sad. We think everyone should be able to enjoy the underwater world - safely, comfortably, and easily.
That's why we created Ninja Shark and our revolutionary line of full face snorkel masks. They're designed to be super comfy, easy-to-use, and make snorkelling accessible for all. Because nobody should miss out on discovering what's under the sea. As a general rule, larger snorkels work well with larger people and vice versa. Longer, thicker snorkels hold a greater volume of air than shorter, skinnier snorkels. To breathe properly, the snorkeler must be able to fully exchange the air in the whole tube.
So, a bigger snorkel means the snorkeler should have the lung capacity to match. That means getting too much carbon dioxide and not enough oxygen. You may feel dizzy, confused, short-of-breath, and fatigued! Thankfully, dry snorkels come in a variety of shapes including skinnier, lighter options for smaller folks! Dry snorkels are the ideal choice for beginners and anyone who has trouble clearing the snorkel when it fills with water.
Many seasoned snorkelers also prefer dry snorkels due to their comfort and ease of use. Even people who are good at clearing a wet snorkel when it fills with water sometimes prefer not to worry about it! This is especially true for snorkeling in salt water, which can leave your mouth feeling quite parched! Even though the wet snorkel is more difficult to use, it also still has its merits! Some folks myself included prefer them because they are much lighter and more streamlined.
I like a snorkel that I barely notice! The major downside of a dry snorkel is that even the best float valves can occasionally jam. For some folks, the comfort of the dry snorkel outweighs this occasional inconvenience. Others may find it annoying and not worth the cost.
Additionally, in choppier conditions, a properly functioning dry snorkel can seal frequently. Some snorkelers will find the repeated interruptions to their breathing cumbersome. Lastly, dry snorkels are also more expensive. Because they seal the air inside them when submerged, dry snorkels will be far more buoyant underwater than wet or semi-dry snorkels. Not only can this buoyancy add extra drag to your swimming, but it can also cause the snorkel to tug on your mask strap in an awkward manner.
This tugging may even cause leaks by breaking the skirt seal. The disadvantages of classic wet snorkels all involve your experience level. Upgrading to a semi-dry or a dry is more a matter of spoiling yourself in that case! The current popularity of dry snorkels means there are many options out there for anyone to find a good fit. Below is a top 5 list of the highest-rated dry snorkels. Check price at Leisure Pro. Make sure you try on your mask with the snorkel attached to see how they fit on your face together!
After holding your breath on a dive this was exhausting over time. The purge valve changed all that. Underwater the tube will not fill with water. The only way water can get into the snorkel is via a poor mouthpiece seal or through the top of the breathing tube.
You could pour water in through the top of the snorkel and it would just pour out through the purge valve. Before snorkels without purge valves, expelling the water was rather a chore. Lungs bursting from a dive were still needed to blow the water out of the tube if you wished to remain viewing beneath the surface. They broke the surface after a dive and drained the water through gravity and breathing sea air without the snorkel in their mouth.
A classic snorkel, those without purge valves, is just a tube of plastic. Thus water in the snorkel could only come out of the two entrances. Either out through the mouthpiece end, where some water would have remained in the bend, or out through the top. A purge valve allows water to drain out like a bathtub. With a huge amount of water in the tube, it will just gush out, like when you resurface after a dive.
Should water enter the tube while face down on the surface, there remains the possibility that water build-up will block airflow. A light exhale will push the water back out into the ocean. It makes snorkeling a lot easier. Many snorkel rentals may even be classic snorkels without one.
