    ThOR 5 LRF 640 3-24x

    Recognizes a hog at 150 yd38° apparent FOV — how big the view looks

    The ATN ThOR 5 LRF 640 3-24x ranks #78 of 80 640-class scopes on image: a budget play — you give up some image and keep $799 (image 64, class median 73; $3,195 against $3,994). The same Chinese core sits in the ATN ThOR LTV 640 2-6x at $2,099.99 — the extra $1,095 here buys the 35mm lens and the rangefinder.

    Pros
    • Built-in laser rangefinder
    • ~10 h battery
    Cons
    • 40 mK — noisier in low light
    • Heavy for its class · 39.56 oz
    • Image 64 — below class median

    What the price buys

    How we compare →

    Computed by comparing this scope against its own siblings on the board — same sensor and lens held equal. Refreshed with every catalog update.

    +$945 of packaging on the same picture
    Same 640×480 sensor and 35 mm lens as the ThOR LTV 640 3-9x at $2,250. The extra buys a rangefinder — not detail at distance.
    Compared with ATN ThOR LTV 640 3-9x ($2,250)
    This packaging premium buys a sensor step
    The +$945 of packaging here is more than the $760 it costs at ATN to step a sensor 320×240 → 640×480 — priced from 6 matched pairs in the lineup. If seeing farther is the goal, spend the spread on the sensor, not the packaging.
    Compared with ATN ThOR LTV 640 3-9x ($2,250), ATN ThOR LTV 320 4-12x ($1,330), ATN ThOR LTV 640 2-6x ($2,100)
    The rangefinder costs +$695 here
    Same scope without it — the ThOR 5 640 3-24x at $2,500. The extra buys the rangefinder, nothing else.
    Compared with ATN ThOR 5 640 3-24x ($2,500)

    The going rate

    Priced $1,009 under the going rate for its build.
