SECOZOOM 3-9x42 Glass Etched Tactical Rifle Scope Optics Mil Dot Compact

1.If waterproof riflescope can get access to water or not?

The riflescopes from us can keep working perfectly under water. However, please note the fact that in order to lengthen the working life, please dry it with lens cloth and put in moisture-free and dry environment after getting wet.

Don’t put in humid environment for a long time. Keep Dry with desiccant.

2.Use Scope Mounts Correctly

If the scope is always clipped very tightly, it may cause scope tube deformation. You don’t need to clip the mounting rings too tightly, you may check if the optics move away after ten fire. If displacement, make adjustment accordingly.

After each shooting, loosen the screw of the mounts to let scope relax so as to minimize the stress of the scope. The scope will only be stressed while in use.

When you put away your rifles, don’t leave the rifles pressing on riflescopes, because the heavy weight of the rifles will probably cause damage to the mounts or the scopes. Don’t leave other items pressing on the scopes neither especially the rifles and lenses will got pressed or cause screw loosed in transit by shock and bump.

3.Installation of Mounts

When you find the windage and elevation turrets have reached the maxi limit but the deviation of bullet is big, please check your mounting rings to make sure the scope is in the middle of the mounting rings without no lateral force that cause unparallel of axle wire of the scope and the rifle. Showed in the picture below, the lateral force may cause the unparallel of the central point of the mounting rings and the central point of the scopes and cause impact error.

4.How to observe the parallax?

Parallax is a condition that occurs when the image of the target is not focused precisely by misalignment of shooters eye on the reticle plane. This condition exists in all scopes. Parallax is visible as an apparent movement between the crosshairs and the target when a shooter moves their head and changes eye alignment in the scope.

The higher the magnification the more visible this is.

Without touching the rifle, move your eye around behind the scope. If the crosshairs appear to move on the target, the parallax is not set for the range of the target you are using.

SECOZOOM scopes equipped with an adjustable parallax knob can correct this at all yardages.

This side parallax knob is located opposite the windage knob on the other side of the scope for models with adjustable parallax. The parallax will be fixed at 100 yards.

If your crosshairs move to the right on the target’s image when you move your head to the left, the image place must be further away than the crosshairs. To pull the image plane in, screw the objective bell in (counter clockwise) so that the objective moves closer to you.

In this set up, the image is essentially tied to the objective so moving the objective 0.1mm moves the image 0.1mm. Adjust outward to pull back.

5.If there is parallax, what can we do?

Adjust the scale marks of side focus knob identical to the sighting range, for example, if your target is in 200 yards far away, adjust your side focus to 200 yards.

6.The relation between the parallax and the eye relief?

There is no direct relation between the the parallax and the eye relief.

Actually, even if you put your eyes within the eye relief, there may still be parallax.

Because the parallax is caused by the relation between objective lens and crosshair whereas eye relief is the relation between the eye and eyepiece.

A zero parallax riflescope has no parallax at all yardages no matter within eye relief or not and no matter there is lateral deviation or not.
