4. UV protection

Choosing a Swimming goggles with UV protection function can effectively block the damage of ultraviolet rays to the eyes.Generally, electroplating goggles have the function of anti -ultraviolet prevention.

5. Material and durability

High -quality electroplating goggles are usually made of durable materials, such as silicone or rubber, which has a long service life.Check the material and structure of the swimming moster to ensure that they are firm, soft and comfortable.

6. Anti -fog performance

Anti -fog performance is also a factor that needs to be considered when choosing a plating goggles.Although the anti -fog effect may weaken over time, choosing a Swimming goggles with anti -fog function can reduce the problem in this area.

How to use a sight to aim

1. Visual differences return to zero

Newly bought new sights need to complete an important task before use: to zero the vision of the scope to reduce the shooting error and improve the accuracy.

2. school sight

Select the target target 10 meters away, aim at the target heart, take 5 rounds as a set of shooting, and adjust the knob according to the position of the bounce.For example: the bouncing point is distributed at the bottom right of the target heart, adjustable air biased knitting knobs, rotating the knob along the direction of L, so that the bounce point moves to the left in the horizontal direction, until the bounce point is basically directly below the target heart;Rotate the knob along the U direction, so that the bounce point moves slowly upward in the vertical direction until it basically coincides with the target heart.

The method of debugging of the scope

1. Set a white paper target, order a black spot at the target heart, hit the centers centered on the black spots, and then retreat to one hundred meters to set up a gun to fix the table, install the sight on the gun.

2. Remove the bolt, aim at the black spot on the white paper target from the barrel through the refractive mirror, and then hold the gun body, then press the cross from the sight of the sight to the black spots on the white paper target. Tighten it tightened.Aiming at the mirror adjustment knob.

3. The guns do not move in a fixed state, install a bullet with a bullet, and start!

4. Check the bomb point. If you are too upper, you can fine -tune the sight of the sight. If you are partial, fine -tuning, and the left to the left, and the right is fine -tuned to the right.

5. Take another shot and look at it again. Repeat this method until the bounce point is hitting the black spots on the cross on the white paper target, and the sight will be adjusted.

The debugging skills of the scope

1. When aiming, pay attention to the distance of the pupil, that is, the distance between the eyes and the sight, and the pupil distance has two effects. One is to avoid damage caused by the rear power to the human eye when shooting.The person's eyes can get the largest imaging area at the distance of the pupil.

2. When aiming, the human eyeball must be the same as the axis of light aiming, otherwise there will be vision.Aiming errors.On time, the surrounding shadow areas are uniform ring -shaped. The performance of the vision is that the shadow areas around the imaging area are uneven. Once the crescent area appears, the projectile will be biased towards the larger part of the crescent area.

3. There are two buttons in the middle of the sight. There are protective caps on these two buttons. After you spin the lid separately, you can see these two buttons.The button in the middle is increased.For example: there is a UP, one is down, and the direction of the UP will be automatically corrected upward.If you turn in the direction of down, the original bounce point will be automatically corrected downward.UP means upward in English, down means downward.The bounce point is biased down, and the direction of the UP indicator is turned. If the hit is high, follow the direction of writing down.In the knob on the side, the above is written by L, and one is written by R. If you turn along the direction of L, move the point to the left. If you turn in the direction of R, the bounce point will move to the right.L and R are capital of the first letters in English left and right, respectively.

4. Aiming a look at 1/4 inches at the British 100 yards (equivalent to 91 meters).The discounted public system is 6.35 mm.If there are about 30 mm (3 cm) in the horizontal direction of the bounce point and the target heart. If a grid at 91 meters is 6.35 mm.Then the actual movement volume of a grid at 10 meters, a look at the grid, is equivalent to 1/4 inches at the British -made 100 yards (equivalent to 91 meters).The discounted public system is 6.35 mm.There are about 30 mm in the horizontal bomb and target heart. If a grid at 91 meters is 6.35 mm.Then the actual amount of movement at 10 meters is to remove 9.35 with 9.35.Finally, about 0.7 mm.The adjustment amount is 30 mm.With 30 divisions of 0.7, it has to be screwed about 43 blocks.If it is a 30 -meter adjustment of one grid, it is 2.16 mm. If 30 meters 30 mm, it is 13.8 that is to twle out 14 grids.
