RIX RNV-31
RIX's budget articulating dual-tube goggle with Gen 2+ tubes, manual gain, IPD stops and per-pod shutoff, about 470 g. Follows the PVS-31 layout but with a chunkier polymer bridge and RIX branding on the pods; the optional dual-18650 external pack is a distinct RIX accessory. Green and white phosphor versions exist.
Analog night vision — an image-intensifier tube. No screen and no lag, and it works passively with no IR lamp running. This is the kind you can move and shoot under, and it is why it costs what it costs.

Understand it first
Night vision, explained honestly
Why it costs what it costs, what the specs mean, and where the money actually goes.
The legality questions worth asking before you buy
Not legal advice — a checklist of the places where gear law actually bites, so you know what to look up.
Helmets, shrouds, and the NVG mounting chain
Bump vs ballistic, why high-cut took over, and how night vision actually attaches to your head.
Thermal vs. night vision: two different senses
One amplifies light, one sees heat — what each is actually for, what thermal can and cannot see, and what the money buys at every tier.
IR lasers and illuminators, aimed responsibly
How aiming under night vision actually works, what the power classes mean, and the discipline of invisible light.
