Nocpix QUEST H50R 640X512 50MM 4X Thermal Binocular With Rangefinder vs AGM ObservIR 35-384 4-20x LRF Thermal Binoculars

Buy the Nocpix QUEST H50R if image detail and long-range detection matter most: its 640x512 sensor, 50mm F1.1 lens and dual 1920x1200 eyepieces resolve more than the ObservIR's 384x288 core. Buy the AGM ObservIR 35-384 if you want one unit that also does 4K digital day/night, GPS and an IR illuminator, and you value a lighter 2.01 lb body. The Nocpix is listed at $3,999.00 at Carolina Sportsman Outfitters as of October 31, 2026; no current price was given for the AGM.

    What reviewers say

    AGM ObservIR 35-384 4-20x LRF Thermal Binoculars

    Reception is thin, with only two ratings, but both are 5 out of 5. Owners tend to value the combination of thermal, digital day/night, and rangefinding in one unit.

    Pros
    • Useful fusion of thermal and digital channels
    • Rangefinder accuracy and reach
    • Solid build and waterproofing
    Cons
    • Heavier than expected for handheld use
    • Thermal image gets soft at high digital zoom

    Questions and answers

    Which is better for long-range scanning?
    The Nocpix. Its 50mm F1.1 lens and 640x512 sensor detect out to 2,850 yards versus 1,800 m for the AGM, and the higher resolution shows more detail at distance.
    Does the AGM do anything the Nocpix cannot?
    Yes. The ObservIR adds a 4K digital day/night channel, GPS and an 850nm IR illuminator, and it is IP67 waterproof. The Nocpix is thermal only.
    Is the Nocpix worth the extra money?
    If most of your glassing is at long range or in open terrain, yes: the bigger sensor and lens are the main reason to pay more. If you want day/night fusion and a lighter body, the AGM is the better fit.
    Which has better battery life?
    The AGM runs up to 8 hours on removable 18650 cells and ships with four. The Nocpix uses an internal USB-C battery plus a hot-swap IRB-2 18650, so you can change power without shutting down.
    How do the rangefinders compare?
    Both are laser rangefinders rated to about 1,000. The Nocpix reads to 1,000 yards in single or continuous mode; the AGM reads to 1,000 m with ±1 m accuracy.
    Which is easier to carry?
    The AGM, at 2.01 lbs with an IP67 rating. The Nocpix's 50mm objective makes it the larger, heavier unit, though it comes with a binocular harness.
