FAQ

A flat top unprotected 18650.

ZULUS scopes have a 2 year warranty.

The IR light is fully adjustable allowing you to have a wide flood for closer range or a tight spot for further distances.

In normal operating mode, short press the power to enter standby mode. You will know you have entered standby mode when the top light turns orange and the screen is off.

45mm

Yes, the Zulus is a digital scope that will show full color for day use and monochrome for night use.

Yes it is  IP67 waterproof.

.50 BMG rated

That depends on the amount of ambient light like dusk or dawn. But for truly dark nights the ZULUS has a built-in infrared illuminator to help you see in the dark.

Yes, the scope has the option to turn on and off a built in microphone adding sound to the video you are recording.

This is to prevent the IR illuminator from overheating. When IR illuminator brightness is set to level 4 or 5 it can generate a lot of heat. In order to protect the ZULUS the illuminator will automatically drop to level 3 after 10 minutes of use. All brightness levels will automatically turn off after 30 minutes of continuous use.

26 in total A-Z

To get into night mode you long press the left arrow while the screen is in normal operating mode NOT in the menu.

Changing the reticle and the color is done in the zeroing menu.

Long press the left arrow to save and exit.

When you are in night mode, short press the left arrow. This will allow you to change the IR illuminator brightness. There are 5 brightness levels and an auto brightness mode.

When in the zeroing menu short press the power button to freeze the image.

There are 2 ways the first is long press the right arrow this will activate the wifi. The second way is to go into the settings menu amd scroll to wifi and turn on.

Go into the settings menu and scroll to the Bluetooth option press the up arrow to enter and turn on.

Recoil Activated Video. If the recoil impulse is high enough the ZULUS will record what it sees a couple seconds before and after a shot is taken. That way in case you forgot to press record manually, you can still get a video recording of your shot.

Approximately 450G of force. For example a 5.56/.223 Remington can activate the RAV but not a .22lr or most airguns.

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).

ThermNight TNC have a 2 year warranty.

More often than not, the problem is usually caused by poor contact of the battery cap.
Ensure that the battery cap is securely tightened.
Clean the internal threads of the battery cap to make sure there’s no dirt or any other debris that could block the circuit contact.

This is to prevent the IR illuminator from overheating. When IR illuminator brightness is set to level 4 or 5 it can generate a lot of heat. In order to protect the ZULUS the illuminator will automatically drop to level 3 after 10 minutes of use. All brightness
levels will automatically turn off after 30 minutes.
And for the LED type illuminator, the maximum brightness level is only 3. It will not dim automatically, but it will automatically turn off after 30 minutes of continuous use.

No, the ThermNight TNC comes with a built-in 32GB memory card.

Measure the distance from the center of the top digital scope lens to the center of the barrel.

Yes, do not aim the thermal scope at strong heat sources such as the sun or fire, as this can damage the thermal sensor permanently.

It’s normal. After zeroing at a specific distance, the reticles align at that distance, and when the aimed object is off the zeroing distance, the reticles do not align at same reference (it doesn’t affect the holdover/dial in calculation result)

There’re several steps to get both night vision and thermal channel zeroed.
1. One-shot zero the night vision channel,
2. There’s no need to shoot for the zeroing of thermal channel. After your night vision channel is zeroed, switch to thermal mode, and use the same heat spot as a reference(such as a hot bottle of water).
Shift the thermal reticle to the same reference area, make sure the thermal reticle is aligned with night vision reticle, and save it.
Note: Both night vision and thermal channel need to be zeroed for accurate target shooting.

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. The ballistic algorithm has been tested through live shooting and theoretical analysis, ensuring sufficient accuracy to meet the requirements of different hunting scenarios.

Only if you are using the In real-time calculation mode, a continuous connection is required if not the ballistic calculations cannot be performed. The other option is ballistic table call mode which allows the ballistic data to be uploaded to the device and no phone is needed after the upload is completed.

There are several reasons for the ranging error.
1. The target is out of range. Our built-in LRF can range from 5 yards to 1100 yards.
2. The target might not be reflective enough for the laser range finder pulse to bounce back and be measured.
3. Weather can affect the LRF performance such as fog or heavy rain.
4. Something might be blocking the LRF, check to make sure the aperture is clear.
5. Possible hardware issue. Please contact us with any problems.

The LRF is fixed at the factory so if you zoom in the LRF aiming reticle may be outside your current FOV. Scroll back and reduce magnification to see LRF reticle.

The angle of the rail or mount does not affect the calculation results. As long as you input the correct scope height by measuring center of lens to center of the barrel (**BORE?), zero distance, actual parameters. normal input of accurate scope parameters is sufficient.

Take a pair a calipers or a ruler and measure from the center of your barrel or bolt.firing pin to center of the scope lens. Make sure you measure straight and not at an angle. For the ThermNight measure from the digital Day/NV objective lens, not the thermal lens.

Two things to watch out for.

First after you have changed the parameters make sure you long press left arrow to save; otherwise, the data changes will not take effect.

The second thing is made sure the changes you made were done on the correct profile letter A-Z.

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.

Your zero is now too far away from the fixed LRF aim point. Simply reduce the magnification until the rangefinder box or spot appears on the screen for measurement before you zoom in.

Aiming method is used when you have enabled the ballistic calculator. With the proper ballistics entered into the app, your digital scope will show you where to aim for the ballistic drop at that distance. Hold over will show you a hash mark relative to your zeroed reticle. The Dial-In option will move the reticle to the ranged position. Clear the laser range finder measurement by pressing and holding down the LRF button and the reticle will move back to its zeroed position.

Ballistic table call will allow you to send one ballistic profile to the scope so you don't have to stay connected to the phone.

Google Play may not support some phones, preventing the download through the Google Play Store . Email us at info@dntoptics.com to request the latest installation package.

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.
