About the device
Description
Thermion 3 LRF thermal imaging riflescopes are designed for use both at night-time and during the day. They provide exceptional image quality even in adverse weather conditions such as fog, smog and rain without being hindered by obstacles like branches, tall grass, dense foliage, or other debris.
Unlike riflescopes based on electrical-to-optical converters, thermal imaging riflescopes do not require an external light source and are resistant to high levels of illumination.
The riflescopes are equipped with a high precision built-in laser rangefinder which allows distance measurement up to 1200 meters.
These riflescopes are designed for hunting, target shooting and recreational shooting, observation and orientation.

Using the Laser Rangefinder
The riflescope is equipped with a built-in rangefinder, allowing you to measure distance to objects up to 1200 m away.
How the rangefinder works
1. Turn on the riflescope, adjust image according to section Powering on and Image Setting.
2. Briefly press the LRF 
3. Point the rangefinding reticle at an object and press LRF 
Notes:
- If the rangefinder is idle longer than 10 seconds, it turns off automatically.
- The point of aiming of the rangefinding reticle and the aiming reticle might not coincide due to aiming reticle shift after zeroing.
- To see the recommended aiming point while measuring the distance, activate the Ballistic Calculator.
Operation in SCAN mode
1. Turn on the rangefinder by briefly pressing the LRF 
2. Hold down the LRF 
3. In case of unsuccessful measurement dashes will appear on the display.

-> Reticle Type
.
- Units of measurement (meters or yards) can be changed in see the System Settings
-> Units of measurement
section.
Additional Information:
- 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 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 sized target.
- Accuracy of 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.
