02Pros and cons

From the published specs. What owners report is in the next section.

For it

High-resolution 1280×1024 sensor, 4× the detail of the common 640×512
Sensitive sensor that picks out small heat differences on humid or rainy nights (the best of 285 that publish it)
Smooth 60 Hz picture on a running animal
Built-in laser rangefinder
Swappable battery pack, so a spare doubles the run time
Light at 24.7 oz, 3rd-lightest of the 22 binoculars here
Waterproof (IP67), survives a dunking

Against it

Only 4 h of battery
Rangefinder but no ballistic calculator, so holdover is up to you
Zoom past 2× is digital and gets blurry

03What owners say

owner discussions, 2026

Summarised from 8 public owner discussions in 2026. Owner experience, not a measurement.

The QUEST S50R reached owners in the UK and Europe months before the US, so most owner material comes from British buyers filming everything from rugby matches to a drag strip. One called it the first real HD civilian thermal, and the detail at short range is what draws comments; at distance, owners report picking out a person at about 650 m and things out to 800 yards with the rangefinder. Using both eyes is the other appeal: an owner who also has a Nocpix Vista monocular uses the Quest far more because it is easier on the eyes over a long session.

The main complaint is the display. Two owners say it does not get as bright as Nocpix's monoculars even at the top setting, and one who came from a Hikmicro Lumi H35R sent his back because the picture looked dim and washed out in white hot. Another owner's explanation is that Nocpix tunes its newer processing for hunting, picking living things out cleanly against the background at the expense of foliage detail, so people buying it to observe rather than hunt may prefer a different maker.

What owners like

Short-range detail is what owners and viewers comment on first: 'you can count the lady's eye lashes' was one reaction to footage.
Two-eyed viewing is easier on the eyes over a night than a monocular; one owner with both a Quest and a Vista reaches for the Quest more for that reason.
Focus dial is easy to work one-handed, and the binocular stays light enough to carry on a chest harness.
Goes to sleep when lowered and wakes when raised, so owners on a chest harness are not rebooting it all night.
One owner gets roughly four hours per 18650 and carries spares; it also runs from a USB-C power bank when static.

Common complaints

The screens do not get as bright as Nocpix monoculars even at 10. One owner sent his back over it, and another who noticed the same says the screen flashes bright for a moment at power-on, so he believes the cap is in software.
Processing favours picking out animals over background texture, which hunters like and observers do not; a buyer coming from a Lumi H35R found the image flat by comparison.
Focus is very sensitive at this aperture: subjects moving toward or away from you drift out of focus quickly, and with the rangefinder running continuously one owner found focusing hard to keep smooth.
Recorded clips look noticeably worse than the live view, and owners say uploads lose most of the detail.
Handheld footage at full zoom is shaky enough that owners add a monopod or tripod.
The battery cover is sealed very tight, so open it carefully the first time.

Is it any good for observing wildlife rather than hunting?

Owners are split. One hobbyist who watches wildlife in towns and the countryside returned his because it looked dim and less detailed than his Lumi H35R. Another owner explained that Nocpix's newer processing is aimed at hunters, showing living things against the background strongly but with less foliage detail, and suggested a Pulsar Merger, AGM or Guide binocular for observation.

Can I buy one in the US?

In early 2026 US buyers could not get one yet, while UK owners had been using them for months. A US buyer who tried to order ended up with a different Nocpix model instead.

How long does a battery last?

One owner puts it at about four hours per 18650 and carries six; he also runs it from a USB-C power bank when he is set up in one spot.
