It's Affect On The Operational Range And It's Manoeuvrability
The first time a spear fishing beginner handles a speargun, is really special. This occasion involves getting to know the initial feelings when swimming with a speargun in the hand. The beginner must learn about the functioning of this tool under the water.
By learning about the movements of the body, they feel a shortness of breath when pulling the trigger of the speargun and recognise the sensations of standing still and aiming at the prey. Of course there are always exceptions with some individuals.
However, I believe that for the first encounter with spearfishing, the most appropriate speargun length is 75cm.
A bigger speargun length would hardly be more appropriate for beginners, who are only just familiarising themselves with using a speargun. A speargun length of 90cm has a longer range, but still agile and has the widest of uses.
However, the beginner is not expected to immediately successfully hunt larger fish specimens; therefore, the first lesson should be to learn about observing the sensation of handling a speargun.
The shorter speargun allows the beginner to more rapidly develop routine. A shorter speargun is easier to strain and with that the possibility that an inconvenience happens is greatly reduced.
For example: when the speargun activates accidentally, it can lead to shabby fingers or sore plexus area.
For beginners it is essential that they get to know spear hunting and speargun operation, therefore, the quantity and size of the catch are of little importanc.
I am convinced that the choice of a short speargun will bring to a beginner a much more pleasant experience and a quicker conquest of the necessary spear hunting skills.
On the other hand, it is difficult to talk about the unnecessary additional cost in terms of when the beginner will quickly outgrow the speargun, as I can state with confidence that the majority of beginners learn the first steps in initiative from another spear hunter, who has some experience.
By this I mean that the first steps are not always conditional upon the purchase of a speargun, as it may be possible to borrow one from friends or acquaintances. At worst, you can buy a cheap second-hand speargun, that will have smaller speargun length.
In most cases a beginner will turn into yet another spear fishing addict. If you enjoy it from the very beginning, you will soon find out which length of speargun best suits you.
In any case, the beginner?s first (short) speargun will not become redundant but can later be used for fishing in cloudy water or for cave hunting.
Other human factors affecting the selection of the appropriate speargun lenght:
Here the spear fishing technique most suitable to a specific hunter is in question. Some prefer to stay close to the coast; others due to their psychophysical abilities would rather hunt in deep waters. Then also material costs are important as the last criterion, particularly with "blue water hunting."
Let me point out here also other factors, such as: configuration of the hunting ground, tradition, and some specifics in spearfishing in certain local areas.
The length of the speargun nevertheless is mostly a personal choice for the spear hunter, when they are no longer a beginner and have already mastered spearfishing techniques and have enough experience to know their own preferences.
A key influence in the choice of the speargun length, therefore represents a personal sense of the hunter, considering the type of hunting which they prefer; and as a result will be most frequently performed.
Impact of material of the speargun length:
At first glance, it seems we can really choose between any type of material with which to produce a speargun. In practice, however, this is not so.
As we are limited by the length of the gun and the type of straining, upon which certain technical limitations of specific material appear. I will state only some of the most typical examples.
Wood can be used only for the power band spearguns. Using slings on spearguns in terms of functionality requires a certain length of the gun body. Rigidity of the wood to the length of the speargun above, has no restrictions.
Aluminium has proven to be the ideal material for the manufacture of compressed air spearguns. It is these types of guns (pistols) that can be the shortest.
They are suitable for cave hunting (hunting in holes). Also sling spearguns are manufactured from aluminium.
In theory, plastic can be moulded into any form without restrictions. In practice, however, it would appear that long spearguns with a plastic body suffer from unwanted bending at higher loads (strong power bands).
Carbon, which has been used for the production of spearguns over the past decade, is a strong and a very light weight material.
Carbon fibres enable the production of arbitrary shapes with sufficient rigidity and robust body structure of the speargun. In doing so, the limit of the length is the same as with the wooden spearguns.
A speargun made of carbon is relatively light, therefore, for hunting from bigger distances, the spear hunters divide into those who support and those who oppose the use of carbon. Very long spearguns for launching a long and heavy harpoon, do not have the sufficient mass to absorb shooting kickbacks.
Agility is an important characteristic of a speargun, and it represents the ratio between the energy that the hunter puts into the movement of the speargun and the speed with which it follows the movement of the fish.
Manoeuvrability of the speargun decreases with the increase of its length. The handle installation also has an impact on the manoeuvrability of the speargun. The rear handle is typical for a European type of speargun.
A middle handle is typical for an American type of speargun and is used with guns of larger dimensions. Middle handles improve the manoeuvrability of the speargun in the direction of left right, as it allows a so called centred rotation.
Centred rotation is enabled by the hunter?s left hand that is lying on the rear of the gun. This way of handling the speargun is used in the technique of "Blue water hunting" and hunting in the fall. These spearguns are made for catching bigger pelagic fish and are considered to be the most powerful spearguns.
Spearfishing techniques affect on the lenght of the speargun:
For cave hunting, the most suitable spear guns are short, compressed air guns. They enable successful hunting when shooting at short distances in confined spaces.
Inshore fishing is probably the most widespread form of spear fishing, for which lengths of 70 to 100cm are suitable. Spearguns are of all types, shapes and materials and are considered the most versatile.
These spearfishing techniques include also fishing and hunting in cloudy water and foam-hunting (in turbulent water). The main technique is a combination of sliding, stalking and waiting for the prey in coastal areas of the sea.
Hunting in depths requires a longer speargun. Lengths are usually from 110-130cm, strong but still precise, however with worse agility that is perhaps not such a relevant issue with this method of hunting.
This is mainly a form of hunting in the fall, where the hunter turns towards the fish with their whole torso. When hunting in deep waters, the hunter dives down to the seabed (sea bottom) and there, with a long and strong gun, predominantly stays still and waits until the fish comes forward to within the spearguns range.
Blue water hunting is a hunting technique for large specimens of pelagic fish in the open seas. This type of spear fishing is carried out by the hunter with a large and fully immersed speargun in a few meters deep water (in the blue), where they wait for the fish?s visit.
Guns of this type allow a shot at a fish from a greater distance, 6m and more, the most powerful guns can even reach from 10m.
