How to make a crossbow for spearfishing?

The crossbow for underwater hunting is an extremely popular weapon among avid fishermen. This means of fishing is distinguished above all by the high accuracy of firing and the reliability of the design. The best crossbows for underwater hunting always look preferable, along with the same pneumatic guns because of the special ease of operation.

Principle of operation

By design , the crossbow gun for underwater hunting is practically no different from its land "fellows". As a matter of fact, the adaptation is presented in the form of the case with a hollow under an arrow and the stretched drafts. The latter are held in a charged position by a special harpoon, which is fixed by means of trigger elements. Pressing the trigger leads to the release of the rods, which give the boom the necessary acceleration.

Type of barrel

The crossbow for underwater hunting contains the head part, which can be represented in such variants:

1. Open - offers the hunter a better visibility and is characterized by increased power.
2. Closed - stands out among other solutions with improved accuracy, which is provided by the presence of twin rods.
3. With one thrust - is a good choice for hunters who are willing to sacrifice accuracy for obtaining maximum power.
4. Mixed - it uses a specific, annular steam draft, which makes it possible to increase the power of the weapon without compromising accuracy. Such a head part is best suited for the production of large fish.
5. Hydroformed barrel - allows you to get a perfectly smooth, verified shot trajectory to perform the most accurate shooting.

With regard to traction, they are of different thickness and length. For hunting relatively small fish it is advisable to use crossbows, where the head part is completed with thin drafts. To produce a large "catch" fit the thickest thrust.

Benefits

Among the advantages of crossbows for underwater hunting is worth noting the following:

• Minimum swing of the weapon during the shot, which affects the increase in accuracy;
• Simplicity of design;
• Affordable cost;
• When operating, there is no need to use additional accessories, for example, a pump, which acts as an obligatory means for charging pneumatics;
• Noiseless shooting.

disadvantages

The obvious disadvantages, which distinguish the crossbow for diving, are: increased probability of damage to the released boom, impressive dimensions of the structure. In addition, the user does not have the ability to regulate the force of fire, and the combat power is reduced by an order of magnitude in comparison with pneumatic rifles.

Crossbow for underwater hunting with their own hands

To begin the handmade weapon manufacturing for underwater fishing follows from the search for a suitable spring. The diameter of the turns of the latter should be of the order of 12-15 mm, and the pitch - not less than 2 mm. It is necessary to take into account the fact that the springs work on compression. Therefore, the length of this element should exceed the dimensions of the body of the self-made crossbow by about 100-200 mm. Consider possible shrinkage of the spring as the weapon is used.

With regard to the parameters of the trunk, the most convenient for hunting in most water bodies is the length of about 60-75 cm. Any lightweight tube with side openings for unimpeded water outlet is suitable for the role of this structural element. In such a trunk a notch under the sear is cut. The metal is also turned out to be a cap and a bloomer. Towards the latter will then be attached traction.

To make a full-fledged crossbow for underwater hunting with your own hands, you will need to prepare a comfortable grip and an effective trigger mechanism. The body and handle can be cut from wood or metal plates. The finished structure is connected with the stem part by bolts.

To complete a crossbow for diving, you need to install a trigger that consists of a trigger, sear, spring and fuse. Preparation of these parts is a fairly simple plumbing work, which any experienced master can handle.

The final element of the crossbow is the line cutter. It can be ground out of sheet metal. The finished plate is attached to the stem plug by several screws. After winding on the arrow to the flies in the front of the weapon, the tench is tied and placed under the ejector. When the shot is fired, the rope comes out from under the plate and begins to unwind after the outgoing arrow.

In the end, it remains only to deal with the crossbow firing. Then you can go directly to the defeat of underwater targets of medium and large size at a distance of about 3 meters.
