Infitac FML19: The Definitive High-Resolution Thermal Sight for 1,100-Yard Heat Detection 

• The INFITAC FML19 is a professional-grade thermal sight engineered for high-stakes, low-visibility missions. This ITAR-compliant optic provides military and law enforcement operators with clear infrared imaging in total darkness or dense fog. Its rugged build mounts effortlessly to pistols or rifles as a primary or secondary thermal solution.
• Sharp Thermal Detail with 384x288 Resolution: This high-sensitivity 12µm sensor identifies minute temperature changes to produce crisp images in the harshest environments. You can see sharper details and more heat signatures compared to standard models for better situational awareness.
• Detect Targets Up to 1100 Yards Away: The 19mm F1.2 lens provides a 50% increase in detection range over the standard FMP13 model. This extended reach gives you more time to identify and react to distant threats before they become a close-range problem.
• Reliable Performance with 1200g Recoil Resistance: Built from AL7075-T6 aluminum, this sight is tested to handle the punishing recoil of firearms like the SCAR MK17 or .50 Desert Eagle. The IP67 rating ensures the unit remains fully waterproof in heavy rain or under 3 feet of water
• Stays Waterproof Down to 33 Feet (IP67): This optic is rated to work in heavy downpours or even if it is fully underwater for a short time. The rugged, sealed body ensures that mud, dust, and rain will not damage the internal electronics or ruin your thermal image.
• 5+ Hours of Runtime on One CR2 Battery: Power through long operations with a reliable internal battery or use the USB-C port for an external power supply. The smart ambient light sensor also saves power by automatically adjusting screen brightness based on your environment.

InfiTac FML19 FAQs

How does the Infitac FML19 help me see in the dark? 

The Infitac FML19 thermal sight uses a high-sensitivity thermal sensor to find heat instead of light. It detects tiny differences in temperature to create a clear picture in total darkness, thick fog, or smoke.

What is NETD ≤20mK and why does it matter?

 NETD measures how well the thermal sensor can identify heat signatures. A lower number like 20mK means the FML19 thermal sight is very sensitive. This is important because it helps you see small details and objects even when they are almost the same temperature as the things around them.

What is InstaWake Tech?

 InstaWake is a smart system that turns the Infitac Fast Mini FML19 on the moment it feels movement. It stays in a power-saving mode when the gun is still but wakes up instantly when you lift it to shoot. This helps your battery last longer while making sure the sight is ready when you need it.

Why are the detection range and recognition range different? 

Detection range is the furthest distance where the Thermal Pistol Sights Fast Mini FML19 can spot a heat signature, which is 1,100 yards for this model. Recognition range is much closer, at 165 yards, because it is the distance where you can actually tell what the object is, like a person or an animal.

Can I use this on both a pistol and a rifle? 

Yes, the InfiTac FML19 2x19mm Thermal Imaging Rifle Scope is a dual-platform optic. It fits standard RMR footprints for pistols but can also be used as a secondary thermal sight on a rifle with optional Picatinny or offset mounts.

Is the screen easy to use? 

The sight has a high-resolution touch screen. You can swipe your finger to change colors, adjust the aiming reticle, or navigate the menu quickly. You can also use the silent buttons if you prefer.

Will it break from the kick of my gun? 

No, this unit is built to be very tough with an AL7075-T6 aluminum body. It is tested to handle 1,200g of recoil, which means it works perfectly even on powerful firearms like a .50 caliber Desert Eagle or a SCAR MK17.

What happens if it gets wet? 

The new Infitac FAST Mini has an IP67 waterproof rating. This means it can stay safe in a heavy rainstorm or even if it is dropped into 33 feet of water for a short time.
