What Is Most Important For Neoprene Wetsuit
The neoprene spearfishing wetsuit differs from ordinary wetsuits in many ways.
With classical diving (scubadiving) the basic wetsuit requirements are entirely different. As the diver carries his air supply with him in a cylinder, he has enough air available.
It is therefore essential that the neoprene provides sufficient thermal insulation for the body and prevents surface injuries of the diver's skin.
The neoprene for making of such wetsuits is thus more firm in structure and usually both-side textile-lined.
Spearfishing, however, is performed in apnea. Breath-holding and diving to great depths are considered a great strain for the body of an underwater hunter.
The properties of neoprene, used for spearfishing wetsuits, are being tailored to the criteria which tend to make spearfishing as comfortable as possible for the underwater hunter.
Due to soft and elastic materials used, the hunter is able to take deep breaths, with minimum oxygen consumption to overcome the resistance created upon his chest by the weitsuit. Having to overcome the resistance namely increases the consumption of oxygen which the hunter needs badly.
In addition to adequate neoprene softness, it is also the shape of spearfishing wetsuit that contributes to the diver's feeling comfortable.
The pants are namely shortened at the top, hence without suspenders and not reaching over the belly. During longer spearfishing periods such pants prove very practical when it comes to having to obey the »call of nature«.
For spearfishing in very cold seas, some manufacturers nowadays even offer pants with open fly front so the hunter can urinate without having to take off his pants.
For the top of spearfishing wetsuit the reinforcement load pad - in the chest area is very important as it enables painless charging of the spearfishing gun. To make the diver feel more comfortable and to reduce heat losses, the zippers across the trunk and on the wrists have been removed.
Due to more intense fish stalking and crawling involved, there were reinforcements placed on the elbows and knees.
Performance of spearfishing at a depth, in cold water or in fish stalking (with minimum movement) also requires the use of a hood. Every underwater hunter should be aware of the fact that in the area of our head as much as 20% of our body heat is lost. Hence the use of hood when spearfishing is highly recommended.
The colour of it plays an important role, too. Here, no bright colours are used as the case with classical scubadiving wetsuits, but rather a number of colour shades which imitate the colours of the environment where the spearfishing takes place.
These are mimetic colours which help camouflage the hunter's body to deceive the fish. Most fish species are namely unable to distinguish colours, yet they can clearly see an outstanding silhouette of the hunter.
Hence the opinions regarding the use of either single-coloured (black) wetsuits or wetsuits with mimetic pattern are fairly divided. Some hunters try to soften their silhouette by wearing the top in one colour, e.g. in mimetic green, and the pants in another colour, e.g. in mimetic brown.
The smooth outer surface of the spearfishing wetsuit reduces water resistance, thus saving some energy for the dive. Underwater hunters are often exposed to wind when wet and the smooth and black outer surface helps the suit dry very quickly, especially in the back and lumbar area.
On the other hand, however, smooth surface between the thighs, around the neck and on arm joints could cause undesired squeaking of neoprene, the sound of which could even frighten the fish away. Yet again, the inventive manufacturers have found the solution to this problem as well.
They have made a spearfishing wetsuit, which is cut from two different materials. For the exposed areas they have used neoprene for smooth outer surface, whereas for the areas between the tighs and on joints the textile-lined neoprene has been used.
The thickness of meoprene depends on the seawater temperature and the spearfishing technique used. For colder seas a thicker wetsuit should be used. In the winter period an undersuit (sleeveless) is also used for the upper part of the body as well as neoprene shorts to be worn over the two-piece wetsuit.
The choice of wetsuit thickness is also influenced by the spearfishing technique to be used. Calm and quiet fish stalking of long duration requires the use of a thicker wetsuit, whereas performing of intense and deep dives warms the hunter's body to such an extent that thinner spearfishing wetsuits can be used.
Every spearfishing wetsuit has a limited lifespan. Neoprene is subjected to compression during deep dives as well as to UV rays, which in time make the neoprene wetsuit thinner and thus increase the heat loss. Due to the cell structure of neoprene, it makes an excellent habitat for microorganisms. Hence careful maintenance, cleaning and, above all, replacing of an aged wetsuit with a new one in time are recommended.
