Night Vision Products - FAQ

Yes, digital night vision can be used 24/7 without the limitation of weather conditions.

One scope, USB cable, rail accessories including M6,M4 screws, mount, spanner and lens cleaning cloth, user manual and an eye protector.

Digital Night Vision have a 2 years warranty.

It’s IP67 waterproof.

32GB - 128GB.

You can use flat-top 18650 batteries with specific dimensions of 65mm*18mm (Note: Some 18650 batteries in certain areas may come with a protection board, increasing the length to 68mm~69mm. These longer batteries cannot be used inside the device).

Recommended to use batteries and micro SD card of reputable manufacturers for better experience.

The scope can endure from firearms to all kinds of airguns, and the parameters are at below:

Maximum 0.338LM

Maximum 800G/S²

Maximum caliber applicability 50 BMG caliber

The main difference between 850nm and 940nm infrared (IR) lights lies in their wavelengths and their respective effects in different applications:

1.Wavelength:850nm IR light has a shorter wavelength compared to 940nm IR light.

2.Visibility:850nm IR light emits a faint red glow that may be visible to the human eye, especially in low-light conditions, while 940nm IR light emits no visible glow to the human eye, making it invisible in most conditions.

3.Detection:850nm IR light is more easily detected by certain animals or surveillance equipment due to its faint red glow, while 940nm is not.

How to choose:

Choose 850nm IR light if you prioritize longer distance illumination and are not concerned about potential visibility to humans or animals.Choose 940nm IR light if you want to avoid any visible glow, making it ideal for hunting applications where detection is a concern.

No, the scope has built-in fill light.

It could detect targets such as wild boar and deer at distances ranging from 450 meters at night.

No, the scope displays brilliant image quality in any magnification.

To update the firmware, you should first download the "Arken Optics" App. Then, connect to the device you want to update. Once connected, switch to the network, check the latest firmware version, and download it. After completing the download, reconnect to the device, and the App will then automatically finish the updating process..

Yes, the scope used novel adaptive noise reduction method and meticulously crafted sound chamber which guarantees an authentic and clearer sound recording.

You don't need to understand complex terms or have extensive knowledge of ballistics. Simply measure and input ballistic parameters accurately to get the ballistic solution. Arken Ballistics' ballistic algorithm has been tested through live shooting and theoretical analysis, ensuring sufficient accuracy to meet the requirements of hunting and shooting.
Ensure that the app has the necessary permissions for Bluetooth, WiFi, and local file access. It is essential to enable GPS location during app usage; otherwise, normal app operation and connection may be affected. Consider clearing the cache or reinstalling the app to resolve connection issues.
Bluetooth and WiFi have limited transmission distances, and increased distances may lead to disconnection or delays in connection. It is advisable to maintain a close distance and minimize obstructions.
The device lacks computational capabilities, so the ballistic calculations are carried out on the phone. In real-time calculation mode, a continuous connection is required; otherwise, ballistic calculations cannot be performed. In ballistic table mode, the ballistic table file needs to be uploaded to the device before accessing ballistic data.
Measure the diameter of the scope tube in front of the bell mouth, then divide that number by 2. Measure the diameter of the scope hood itself, then divide that number by 2. Measure the gap between the bottom of the scope hood and the barrel. Add these three numbers to obtain your scope height.
Google Play may not support some phones, preventing the download through Google Play. Email info@arkenoptics.com to request the latest installation package.
The tilt angle of the rail or mount does not affect the calculation results. As long as you input the correct scope height, zero distance, actual parameters, and the parameter for the tilt angle between the scope and the barrel, normal input of accurate scope parameters is sufficient.
Ensure that after inputting the corresponding parameters, you click save; otherwise, the data changes will not take effect.
The ballistic algorithm includes calculating wind spin drift.
If the ranging distance exceeds the farthest distance set in the ballistic table (end distance), it will prompt "out of range." Resolve this by setting the farthest distance beyond commonly used shooting records. Also, consider setting a smaller step value (incremental distance) for finer calculation results.

Simply reduce the magnification until the rangefinder box or spot appears on the screen for measurement before you zoom in.

It’s normal for the following reasons:

First, the aim spot(rangefinder box) of LRF is fixed after assembly from factory, and the spot is not perfectly aligned at the absolute center of the screen. 

Second, after zeroing the scope, the reticle would actually off the center of the display screen, which might make the off-axial of rangefinder box further. Third, when zoomed in, the distance between the rangefinder box and the reticle(which is always stay at the center of display) would be bigger enough, that crop of display put the rangefinder box aside.

We have overheat protection, when IR pill intensity set at levels 4~5, it automatically reduces to level 3 after 10 minutes of use. 

Other IR pill intensity levels automatically turn off after 30 minutes. And for the LED type illuminator, it has a maximum level of 3, and do not dim automatically, but will also automatically turn off after 30 minutes.
