Quick answer: Nocpix builds one of the most complete thermal ranges in Australia, and the model codes make the whole line-up easy to read once you know them. The letter in a name is the sensor tier — P = 256×192, L = 384×288, H = 640×512, S = 1280×1024...

On a thermal scope, base magnification and field of view are two sides of the same number — both are fixed by the objective lens, the sensor size and the display, and as one goes up the other goes down. Base (optical) magnification is the truest, sharpest view the scope...

Pixel pitch is the physical spacing between the pixels on a thermal sensor, measured in microns (µm) — and for the same resolution and lens, a tighter 12µm pitch gives a narrower field of view, higher base magnification and more pixels on a distant target, while a wider 17µm pitch...

A thermal scope holds zero on a hard-kicking rifle when it's mounted to the correct torque on a solid base — not just bolted on by feel. Thermal optics carry electronics and often a heavier objective bell than a day scope, so under recoil they put real stress on the...
