03What owners say

owner discussions, 2022–2026

Summarised from 11 public owner discussions between 2022 and 2026. Owner experience, not a measurement.

Owners treat the NOX35 as a rifle scope first and a scanner second. The image is the reason people buy it; one reply in a comparison with the RH25 V2 summed it up as the RH25 being more versatile while the NOX has 'that glorious BAE core,' and an owner of the smaller NOX18 says you cannot go wrong with a NOX if you want a crystal clear picture. US manufacture is the other draw: buyers weighing it against Chinese-made units name that explicitly.

The recurring warning is about helmet use. Several owners who run NODs say the 35 is too big and too high in base magnification for a bridge, and that anyone who wants a helmet thermal from N-Vision should look at the NOX18 instead. On the rifle, the complaints are smaller and practical: reticle stadia that only read correctly at one magnification, no built-in recording, and a battery cap that dents button-top 18650s.

What owners like

Image quality is what owners and would-be buyers keep coming back to; the BAE core is the reason people pay more than they would for an RH25 V2.
US-made, which several buyers comparing it to iRay and other Chinese-made units say tipped the decision.
Works as a scanner off the rifle: one owner mostly uses his for scanning and says it still held zero well enough to hit a milk jug at about 50 yards when he did shoot it.
Holds its value. Owners report paying around $5,200 new in early 2023, and wanted posts in 2025 were still offering close to $5,000 for used ones.

Common complaints

Too big for a helmet. Owners put it at roughly 19.5 oz with the weapon mount (about 2 oz less without), say it needs a massive counterweight, and the consistent advice to anyone planning to bridge it with a PVS-14 is to buy the NOX18.
The reticle stadia only work at one magnification; two owners in mid-2026 were still asking whether a firmware update had ever fixed it, and one called it 'pants on head stupid.'
No onboard recording: an owner who later wanted to film his hunts had to go shopping for an external USB DVR.
The battery cap dents the button on button-top 18650s when screwed down; one owner found flat-tops fit cleanly.
N-Vision says the NOX series is not a clip-on. One owner reports it working in front of a 1-8x, but that is off-label use.

NOX35 or NOX18 if I might helmet-mount it?

The NOX18. Every owner who answered this said the 35 is too big and too magnified to wear, and that if you only use it stationary you may as well leave it on the rifle and scan with it. One who runs a NOX18 on a bridge daily says it sits around 16 oz with the weapon mount, versus about 19.5 oz for the 35.

NOX35 or RH25 V2 for a do-everything thermal?

Owners say the RH25 V2 is the more versatile pick because it can helmet-mount and clip on, and it is cheaper. The NOX35's case is the BAE core's image and US manufacture. A dealer who sells both called them both excellent and said the choice comes down to how much you need helmet or clip-on use.

Can it be used as a clip-on?

Not officially. N-Vision says the NOX series is not a clip-on, and owners repeat that. One owner says it works fine in front of a 1-8x and has hit targets that way, but others treat that as luck rather than something to plan around.
