Thermal Fast FAL19/1×34D FAQs
Why is the 384x288 thermal sensor with a 50Hz refresh rate a game changer?
The 384x288 sensor is a special camera that sees heat instead of light, which gives you exceptional clarity. The 50Hz refresh rate means the video updates 50 times every second. This makes the image very smooth and prevents lag when you are tracking a moving target.
What does "Parallax Free" mean and why is it important?
This sight is designed to be parallax free. This means the aiming dot stays on your target even if you move your head slightly or do not look perfectly through the center of the glass. This helps you aim faster and shoot accurately in difficult positions.
What are the different image modes and what do they do?
The FAL19 has four special modes to help you see in different situations:
- Single Red Dot: Shows a standard red dot for normal aiming.
- Single Thermal Mode: Shows only heat images to help you see in the dark.
- Outline Mode: Highlights the edges of heat sources, sometimes called a "breathing effect," to make shapes stand out.
- Fusion Mode: Combines the thermal image with the red dot view so you can see both the target's heat and your surroundings at the same time.
