: A higher base magnification (e.g., 4x) helps for long-range shots but narrows your field of view (FOV). Lower base magnification (e.g., 1x–2x) is better for quick scanning and short-range tracking. Top Rated Models by Category (2025-2026)
: Measures the sensor's ability to detect tiny temperature differences. A lower number is better; high-end optics like those from Pulsar often feature sub-25mK or even sub-18mK ratings for better detail in fog or rain.
: This is the most critical factor for target identification. Entry-level sensors are typically , mid-range units use , and high-end professional models feature
