Classes underwater hunting is simply inconceivable without a well-chosen mask. If between eyes and water no air, the eyes (so they work) just will not be able to give an adequate assessment of what is happening around.
However, some Amateurs, not thinking about the consequences, replace the mask underwater goggles, and very quickly begin to understand that such a choice is clearly unreasonable.
Why? Swimming glasses can be perfectly safe to dive to a depth of two meters. If you dive deeper, the glasses become a kind of suction cups, Prilepskaya to face, and because of the generated pressure can cause such significant problems as, for example, hemophthalmus or sclera of the eyeball. And they often become cause of blindness. For these reasons, only the mask will be a useful accessory for your underwater equipment.
Some practical advice when purchasing a mask
As with any purchase, you first need to pay attention to, how is the quality of the raw materials produced mask. Today the vast majority of them are made of very high quality, pleasant to the touch silicone. And not worth saving.
The best option is a skirt from hypoallergenic silicone. Indeed, in connection with the peculiarities of climate, our hunters have to dive into the cold water – and in it the silicone becomes “stiff” and starts to RUB the skin of the face (especially cheekbones and upper lip). In addition, due to the low temperature (and, accordingly, the loss of softness) this mask is less tight to the face and is leaking faster.
However, the water resistance of the mask for spearfishing is not the only criterion. Remembering that underwater hunter can be underwater for a very long time (because it does not restrict a certain amount of air supply), when buying a mask is necessary to check how well it sits on your face. How to check how accurately it meets the face of the future owner? A good mask will not disappear, if before applying it to your face and you sniff a little air. Moreover, it will not allow you to breathe again. What to do if the hunter unshaven? Just more responsible approach to the choice of the mask, paying more attention to air tightness – that’s all.
It is important to take into account the mask space. At a shallow depth, as already remembered, even glasses will not bring harm. But 10-12 meters under water to offset the pressure caused by incorrectly chosen mask, spent a lot more air. And to avoid barotrauma want to choose exclusively among the masks with a small mask space.
Further – glass. The shrapnel is another danger to the eyes, so the right glass, of course, tempered. It is defined in the English words “tempered” or “safety” written on the sight glass of the mask. This mask is very durable and durable. A tempered glass window will draw the high pressure inherent in the depth, and mechanical damage. Agree that really, swimming under water, to stumble on something like branches or driftwood. And tempered glass is much better resists such attacks.
Not worth to spend money on masks with side Windows. The reason is simple – they are very tiring vision. Why? Side glass reflect sun rays and glare do not allow to be seen around. And another thing: if the mask has a flat monostable, it shows your brain is just one picture, and not increased. Spherical glass acts like a lens, distorting distances and sizes, and the side glass overload peripheral vision.
And if the hunter really any problems with vision? In this case, it will be the mask for spearfishing with diopters. Possible even a personal selection of lenses for the mask and there are various ways of their installation. To proceed it is recommended that the number of diopters in the glasses used in everyday life, but for the mask it is better to reduce it by 0.5-1.5 – this recommendation is due to the refraction of light in water.
Another tip when choosing a mask for spearfishing: perfect color skirt – black, because this is the specificity of our vision. Looking from a bright room window at night, we almost did not see, but from the street we can see very, very well. More darkened the area around the eyes will help to see much better under water. In no case do not buy a mask made of transparent silicone. She misses the light, which will be pale from the window.
The necessary characteristics of underwater masks
Depending on the depth at which hunting is conducted, a mask can be divided into three groups (including visibility):
- Masks for shallow hunting. Hunter needs to see what is in front and what’s underneath, and partially the rear.
- When hunting at the average depth don’t need to see what is happening below. The attention of the hunter concentrated on the situation ahead of him and on the bottom. For there, among relefnosti, among the shells, the fish hide.
- Suitable for deep hunting mask is especially resistant to water pressure. In a small volume she needs to have excellent visibility. Thanks to the matte surface, the sight of the hunter doesn’t get tired. And efficiently manufactured and fastened the strap will be less deformed and pull the mask up. As a consequence, the hunter will feel more comfortable, as will rubbing the skin under the nose.
Finally it is worth noting that the selection mask for spearfishing is a very individual thing. You should not place undue heed to the sellers, only carefully fitting and knowledge of the necessary requirements will allow you to make a successful purchase. Without properly selected mask a hunter is without his main weapon – good vision.
