Digisight Ultra LRF

Yes, you can use the riflescope both at night and in the daytime.

For better performance in the daytime please close the lens cover and use the manual display brightness and contrast settings.

Please make sure:

- your riflescope has the latest firmware version. Click here to check.

- you have correctly and firmly installed the riflescope on your rifle. 

- you have correctly carried out the zeroing procedure described in the user manual.

When setting the zeroing coordinates, the reticle moves along the image which allows a wider range of reticle adjustment.

The reticle movement range makes it possible to successfully zero a riflescope mounted even on a mount far from

being ideal thus minimizing mount's faults. Higher precision of the rifle-mount system requires less movement of the reticle.

We suggest mounting the riflescope as low as possible and make sure there are no inclications in either side, especially vertically.

Yes. The reticle for distance measuring and the reticle for aiming are not supposed to match.

When zeroing the riflescope, the reticle moves along the display (so it may not be in the centre

upon zeroing completion) but the rangefinder's reticle does not move, it's always in the display centre.

Both reticles may be at a different distance from each other depending on 

the way the riflescope was zeroed, click adjustement range used, and mount type.

The Digisight Ultra LRF uses a powerful IR illuminator. This increases detection range and gives the impression of a higher illumination

when seeing objects at a shorter range. In such cases,  we recommend the following:

- reducing the power of the IR illuminator;

- adjusting the position of the IR spot ;

- holding the riflescope a little bit higher;

- using an alternative focusable IR Illuminator installed in place of the supplied IR.

Please take note of the following:

Accuracy of measurement and maximum range depend on the reflection ratio of the target surface, the angle at which the emitting beam falls on the target surface and environmental conditions. Reflectivity is also affected by surface texture, color, size and the shape of the target. A shiny or brightly colored surface is normally more reflective than a dark surface.

Measuring range to a small sized target is more difficult than to a large target. Accuracy of the measurement can also be affected by light conditions, fog, haze, rain, snow etc. Ranging performance can degrade in bright conditions or when ranging towards the sun.

When measuring range to a small-sized target located more that 400 meters away, it is recommended that you put your elbow against a solid surface. This is due to possible hand tremors and difficulty hitting the target with the beam at a longer distance.

在归零之后，十字线可能会稍微偏离视场中心，这属于正常现象，不会影响精度。如果步枪瞄准镜正确安装在您的步枪上，并且安装座妥善固定，那么您可能不需要大幅移动十字线，因此十字线会非常靠近中心。

会，即使电池长时间未安装在步枪瞄准镜中，也会保存用户归零配置文件。

更新固件时，会保存用户归零配置文件。

使用数码变焦时，图像会被裁剪，因此分辨率会降低，并且图像看起来不像使用基础放大倍率（光学放大）时那么清晰。
这是所有设备的数码变焦功能普遍存在的特点，而不是缺陷。

您无法自己完成这一操作。但是，您可以向我们发送十字线类型建议，我们会予以考虑。

所有 Pulsar 数字和热成像步枪瞄准镜都具有最大 6000 焦耳的抗震性能。
请检查您的子弹的这一数值。

产品随附部分充电的电池。
为了获得更好的体验，建议、首次使用前将电池充满电。
