Our verdict
OneLeaf was founded in 2019 around a single product, the Commander NV100 clip-on, and it has grown into a full line of digital night vision and thermal optics without leaving the price bracket where most hunters actually shop. Its strength is practical engineering rather than spec-sheet theatre: Sony STARVIS sensors, standard 18650 cells, onboard recording on everything, and — in the NV100 Plus — a day scope and night unit designed to fit each other so the zero survives the swap. It is digital IR night vision, not tube and not thermal, and the weight and micro USB charging are real compromises. But for a hunter who wants one optic for daylight and night pest or predator work, OneLeaf is the most sensible place we have found to start.
Background
OneLeaf was founded in 2019 and is headquartered in Hong Kong, built by an R&D team the company says has more than fifteen years of experience in night vision and electro-optics. It sells direct through oneleaf.ai and describes its market as hunting, exploring, property protection and law enforcement.
Its first product was the Commander NV100, a clip-on digital night vision unit built around Sony’s STARVIS low-light sensor. It became the company’s best seller and set the template for what followed: the Find NV200 binocular in 2021 with interchangeable lenses, the Commander NV400 in 2022 with a built-in laser rangefinder, the modular NV500 series, and from 2024 the Mars thermal line.
How we use OneLeaf
Our first OneLeaf review is the Commander NV100 Plus — the Rapidfire Plus 3-12x56 day scope paired with the NV100 clip-on, at US$433.20 on sale (US$658 regular).
We mounted it on a Diana Stormrider .22 PCP, zeroed it on paper in daylight, and recorded through it at last light. It scored 4.4 out of 5. What earned the score is the combination: a day scope good enough to leave on the rifle all season, and a night unit that couples to it without tape or adapters so the zero carries straight into the dark — with every shot recorded to the SD card.
What sets OneLeaf apart
It solves the day/night problem directly. Tube night vision cannot be used in daylight, and thermal shows heat rather than a scene. Most budget digital clip-ons leave you to marry them to someone else’s scope. The NV100 Plus is sold as one system, designed to fit, which is what most hunters asking about night vision actually want.
Sensible hardware choices. STARVIS sensors, a standard 18650 cell, SD card recording and a two-year warranty with a support address printed on the card. None of it is exotic, and all of it is easy to live with.
A clear upgrade path. Start with the NV100 Plus; add a handheld thermal for spotting later; move up to the NV400/NV500 or a Mars thermal scope if night work becomes the main job.
What to know before buying
This is digital IR night vision. It sees what its infrared illuminator lights, out to a manufacturer-quoted 300 m for detection — identification range on a coyote-sized animal is shorter. It does not see heat, so it will not pick an animal out of cover the way thermal does.
The NV100 Plus is heavy — about 1.14 kg of optics before rings — and fitting the clip-on moves your eye rearward, so check your head position with it on. Charging is by micro USB, and OneLeaf does not publish a recoil rating for it; we have tested it only on a PCP air rifle.
And night hunting rules vary a great deal between provinces and states. Check the current regulations before using any night vision device on game.
Bottom line
OneLeaf earns its place here by building the night vision setup most hunters are actually looking for — not the most expensive one, but the practical one. The NV100 Plus is one scope for the day and a clip-on for the dark, at roughly the price of a decent day scope alone.
If you want to start doing night predator or pest work without spending thousands, start here.
Why we recommend them
Day and night in one optic. The NV100 Plus pairs a conventional 3-12x56 day scope with a clip-on made specifically for it. Leave it off for daylight; put it on at dusk. The reticle you zeroed at noon is the one you shoot with at night.
Proven core product. The Commander NV100 was OneLeaf's first device and remains its best seller — a STARVIS 1080p sensor, 0.4-inch 3.69M-dot viewfinder at 60 fps and a 6 W 850 nm illuminator.
Records every shot. Video and stills to SD card with a date stamp burned in — useful for confirming hits and recovering animals, and a record of what you did on someone else's land.
Common batteries. A standard 18650 cell rated for about six hours. A spare is cheap and fits a pocket.
Priced where hunters shop. The day/night combination costs about what a decent standalone day scope does, and a fraction of tube or thermal.
