Teledyne FLIR Breach PTQ136
The Teledyne FLIR Breach PTQ136 is a 320×256, 12 µm thermal handheld monocular behind a 9.1 mm lens. On the Johnson yardstick that is an estimated 190 m detection and 47 m recognition range for a standing person; Teledyne FLIR publishes no detection figure. It is the lightest of the 18 handhelds here, at 7.4 oz.

Box claim vs. what the optics support
One pixel of this unit sees 1.319 mrad (12 µm ÷ 9.1 mm). Two pixels across a 0.5 m human is 0.5 ÷ (2 × 1.319) × 1000 = 190 m. The box figure is usually computed against a person’s 1.8 m height instead, which is why it comes out higher. Full explanation.

Derived here
Estimated from pixel pitch and lens focal length using the Johnson criteria (2, 8 and 13 pixels across a 0.5 m human critical dimension), clear air, 50 % probability. A model of the optics, not a measurement — real range depends on temperature contrast, humidity and the animal.

What the spec sheet says
Read from the published specifications and this catalog’s own numbers — not from owner reports, which we have not collected for this unit.
- 12 µm pitch — the 9.1 mm lens sees what a 17 µm core would need 13 mm to match
- 60 Hz core — 20 % more frames than the 50 Hz norm when an animal runs
- Runs on CR123 cells you can swap in the field
- 7.4 oz — 1st-lightest of the 18 handhelds here
- Warranty: 10 years (detector)
- Wide 23.8° field for scanning
- NETD not published — sensitivity cannot be compared on paper
- No detection range published by the maker
- Only 1.5 h published run time
- 320-class core — 2× less field of view than a 640 behind the same lens
- No IP rating published
- Estimated recognition only 47 m — inside typical shooting distance
