Different Types of Snorkeling and Diving Fins

Leave a reply

A lot of science and research goes into the designing and making of the best snorkel fins.

The makers will bring together different blade designs and materials to transfer energy from your leg to the fin for every kick cycle.

When it comes to fins, you have lot of types and styles to select from. Make sure that you get the correct fins.

The Style

Choose from Open Heel Fins and Full Foot Fins.

Full Foot Fins – There are closed heels here. You have to wear these fins with a thin neoprene fin sock, which will give you more comfort or bare foot. These fins work best in warm tropical waters, and also when you are snorkeling just below the surface. You cannot see them when wearing booties. The long foot is lighter, and they cost less too. They are flexible fins with low mass.

Open Heel Fins – Adjustable Open Heel fins are what you usually find. You have to wear dive boots to use them, and are particularly useful in colder waters. The adjustable heel strap makes sure that your foot is kept secured in the pocket. These fins are a bit stiffer as they are constructed from stronger materials.

Open Heel vs. Full Foot Fins

Open Heal fins usually cost more. They are also less bulky and easier to wear. But they can cause friction, giving you blisters if the fitting is not perfect. While selecting a fin for your diving or snorkeling, always make sure that the fitting is good.

Many divers go for Open Heel fins because they are more versatile, comfortable and adjustable. They also provide adequate chafing protection and cushioning. They give thermal protection in cold water when you wear with a dive boot. But they are bulkier and will also cost a bit more. The strap adjustment mechanism is also more complex.

Short Fins – The blades in these fins are usually between 15-23 inches in length. These fins are sometimes also referred to as travel fins because they are compact in size, and they weigh less too. You can carry a short fin in your travel bag easily.

However, remember, you have to kick harder for getting adequate propulsion with these shorter fins, so this may tire out some snorkelers.

You can offset this somewhat by making sure that the material is rigid and the blades are wide enough.

Pro Ear Scuba Diving Mask vs. Full Face Scuba Diving Masks

Leave a reply

There are many types of scuba diving masks available such as the classic model with one big lens (single pane), the modern-day two-window variety (double pane), frameless designs, the ones with bifocal lenses, masks with a purge valve at the bottom of the nose, masks with rubber nose but without opening, low volume, high volume masks and such others.

The best scuba masks however fall into one of these two categories – they are either full face, or ear scuba diving masks. Which one is better? The choice is often personal. They are both popular among expert divers. Even beginner divers can use them both.

Let us take a closer look to understand their features and differences better.

The Pro Ear Scuba Diving Mask

pro-ear-mask

Divers use this mask to keep their ears dry and for equalization purposes. This is done through cups over ears that are attached through flexible tubes to the facemask space. There is a one-way valve in the earpiece. This type of diving mask is best suited for divers who have narrow faces, but for others they can be a bit uncomfortable because they may feel some pressure on their temples when below the water.

Your ears will stay dry though, particularly during diving, and the sealing is fine as well. You will be able to look sideways comfortably. Water never gets into your ears.

Your earpiece will be equalized automatically if you are equalizing the mask correctly. There is no need to develop any new habit to make this happen, which is a great relief for those who have just started diving. However, some debris, like sand, for example, can get into your earpiece tubes. Also, you might face an issue when you are trying to rinse the tubes of this mask.

Full Face Scuba Diving Mask

Full Face Scuba Diving Mask

This kind of mask will seal your complete face as opposed to the ear diving mask that basically covers only the ear. There is also the valve and mouthpiece through which you will get the breathing gas.

Why should you use this mask? Use this type of diving mask when the water is polluted or it is too cold as it will cover your entire face. These masks will protect you better against corals that can prick your face when you get too close, and also from jellyfish stings.

You get more breathing security too with this model. In an ear-only mask, you must always grip the mouthpiece with your teeth to breathe, but here, you can keep breathing even if you have an oxygen toxicity convulsion for some reason or become unconscious. Because of this reason, many professional divers, who go deep into the water, or venture into riskier areas, prefer this mask. Those into recreational diving rarely use them.

With the full face mask, you can see clearly below the water and there is space too for equipment you use to communicate with your surface team.

Use the full face type if you are planning a long dive session, because holding the mouthpiece between your teeth for that long can be uncomfortable.

You can use the ear scuba diving mask if you are just starting off. But after a while, it is probably best to switch over to the full face scuba mask type.

What is the Best Sleeping Position for Pregnant Women?

Leave a reply

Pregnant women need special care. They must be careful as well because the slightest mistake can be disastrous. In fact, during pregnancy, you should look into how you are sleeping too. Some medical professionals have suggested that, would be moms should always sleep on one side and keep their knees bent. This position is the most comfortable to them. Pillows can be placed between the legs, behind the back and under the belly. But the very best position is side sleeping and must be accompanied with one of the best pillows for side sleepers discussed on that website.

When pregnant, you must always sleep on the side. It would be difficult to sleep on the stomach because of your growing belly and tender breasts. But that is not all. You mustn’t sleep on your back too when your pregnancy progresses, because in this position, weight of the uterus will press on your back muscles, spine and important blood vessels. The blood flow in your body and to your baby can get reduced.

Back sleeping during pregnancy can cause other issues too…

  • This can cause swelling, hemorrhoids, pains and muscle aches.
  • Your blood pressure can go down and make you feel dizzy, particularly when you are trying to stand up or sit down. In some women, the blood pressure will actually go up.
  • There can be snoring as your weight grows.

Safest Sleep Position

Back is certainly not the best in your fifth month. There can be extra pressure on your inferior vena cava and aorta. Vena cava are the blood vessels that carry blood from your feet and legs back to your heart. You shouldn’t sleep on your stomach as you can have problems in breathing. Plus, in this position, your belly will push down the intestines, which isn’t good. There can be tummy troubles.

Many caregivers suggest that left is the safest position for the baby, though the right side is safe too. This position is more comfortable too as the abdomen grows. When you sleep on your left, it will be easier for the nutrient-packed blood to travel from your heart to the placenta and nourish the growing baby. Your increasing body weight will not push your liver as well.

Positioning Tips From HealthHeadliner.com

  • Keep a pillow between your knees or below the tummy for belly and back support. By keeping a pillow below your body, you will prevent yourself from rolling into your back or stomach.
  • Raise the head of your bed by a few inches if you have heartburn. You can use blocks or books. The acids in your stomach will stay down.
  • Always use a side sleeping pillow to stay safe.

So develop the habit of sleeping on your sides. But don’t get alarmed if you suddenly wake up and find yourself sleeping on your stomach or back. Just go back to your sides. But having said this, you should use a side sleeping pillow and make every effort to remain in the side position while you are sleeping.
