Nocpix Quest S50R Thermal Binocular vs Pulsar Symbion LRF DXT50

The Pulsar Symbion LRF DXT50 is the more versatile tool: it pairs a 1280×1024 thermal sensor with a 4K digital day/night channel, image stabilization, Wi-Fi and onboard recording. The Nocpix Quest S50R is the simpler dedicated thermal binocular, with a lower-noise ≤15 mK sensor, a longer 1000 m thermal rangefinder and a user-replaceable 18650 cell. Owners of the Pulsar praise its image and stabilization but say the controls take time to learn; the Nocpix is easier to run in the dark and easier to keep powered.

  • Choose the Nocpix Quest S50R if you want a pure thermal binocular with a very quiet ≤15 mK sensor, a 1000 m rangefinder and a swappable 18650 battery you can carry spares for.
  • Choose the Pulsar Symbion LRF DXT50 if you want one device for thermal plus 4K digital day and night viewing, with image stabilization, recording and Wi-Fi.

What reviewers say

Pulsar Symbion LRF DXT50

Owners rate the Symbion's thermal, digital and night performance as a major step up, with image stabilization and rugged build called out as strengths. Most criticism centers on the learning curve and fiddly eyecup protectors.

What people mention
  • Image qualityPraisedOwners call the thermal and digital channels a game-changing step up in detail.
  • Image stabilizationPraisedReviewers count stabilization as a real plus for long handheld observation.
  • ControlsCriticisedUsers say the many controls take a while to learn before dark use becomes easy.
  • Eyecup protectorsCriticisedSome owners find the eyecup protectors get in the way in the field.

Questions and answers

Which is better for spotting game at long range?
The Nocpix has the longer thermal detection range and the lower-noise sensor, so it shows faint heat signatures farther out. The Pulsar's 4K digital channel helps you identify what you spotted once you switch over.
Which has the better rangefinder?
The Pulsar reaches about 1463 m against the Nocpix's 1000 m, so it measures farther targets. Both give a distance readout in the eyepiece.
Do I need the digital channel?
If you observe in daylight or want color identification after thermal spotting, the Pulsar's 4K channel is the reason to step up. For night-only thermal scanning, the Nocpix covers it without the extra complexity.
Which is easier to power in the field?
The Nocpix takes a replaceable 18650, so you can carry spares and swap instantly. The Pulsar ships with two rechargeable AP5 packs, which means recharging rather than swapping in a standard cell.
Which is easier to learn?
The Nocpix, as a thermal-only unit with fewer menus. Pulsar owners say the controls are intuitive once learned but take a while to master in the dark.
