Finest detail at 100 yd
Tube resolution (lp/mm)
How fine a detail a night vision tube can show, in line pairs per millimeter. Higher is sharper, but it is measured in a lab in good light.
~0.7 in
One dark and one light line, from the tube's published resolution and the lens. A lab limit in bright light: under starlight the picture gets coarser, and how much depends on the tube.
Ground across the view at 100 yd
Field width
How many feet of ground fill the screen at 100 yards. Wider makes scanning faster; narrower usually means more detail on the animal.
63 ft
The same as 8 of the 28 other current tube clip-on night vision units we track; 8 show more ground.
Specs
| Tube | |
|---|---|
| Generation Tube generations Labels like Gen 1, Gen 2+ and Gen 3 that group night vision tubes by design. They are a rough guide; the measured specs say more than the label. | Gen 3 filmless ("L3 Filmless") |
| Figure of merit Figure of merit (FOM) A single number for night vision tube quality: resolution multiplied by signal-to-noise ratio. Higher is better, but check whether it is a guaranteed minimum. | 2,200+ |
| Resolution Tube resolution (lp/mm) How fine a detail a night vision tube can show, in line pairs per millimeter. Higher is sharper, but it is measured in a lab in good light. | 64 to 72 lp/mm |
| Signal-to-noise Signal-to-noise ratio (SNR) How clean a night vision tube's picture is in very low light. Higher means less sparkle and grain on dark nights. | — |
| How the maker states these | A floor ("or better") |
| Phosphor Green vs white phosphor The color of the night vision picture. Green is traditional; white shows black and white. Many people find white more natural, but it is a preference. | White |
| Autogating Autogating A night vision tube feature that rapidly adjusts the tube's power when light gets bright, keeping the picture usable near headlights, yard lights or muzzle flash. | — |
| Manual gain Manual gain A knob that lets you turn night vision brightness up or down yourself, so you can keep contrast under a bright moon or near lights. | Yes |
| Optics | |
| Lens Focal length The lens number in millimeters, like 35 mm or 50 mm. A longer lens puts more pixels on a distant animal but shows a narrower slice of ground. | 80 mm f/1.4 |
| Base magnification Base magnification How much bigger things look before any digital zoom, like 2× or 4×. Higher is not automatically better: it narrows your view. | 1× |
| Max digital zoom Digital zoom Electronic enlarging of the picture. It makes the animal look bigger but adds no detail; past about 2× to 4× the image gets blocky. | 1× |
| Field of view Field of view How wide a view you get, in degrees. A wide view makes scanning for animals faster; a narrow one usually means more magnification. | 12° wideArmasight recommends day optics of 3x to 12x (the description says up to 10x). Watchman IR illuminator in the box. |
| Detection range (maker’s claim) Detection range The maker's figure for how far away a warm object shows up as a dot or two. It is far longer than the distance you can tell what the animal is. | — |
| Power | |
| Battery | 1 × CR123A or 1 × AA, removable |
| Runtime Battery life (runtime) How many hours the device runs on a charge, by the maker's test. Real runtime is shorter in the cold and with Wi-Fi, recording or the rangefinder on. | 24 h |
| Features | |
| Rangefinder Laser rangefinder A built-in laser that measures how far away the animal is. The rated range is for big, reflective targets; expect much less on a coyote. | No |
| Riflescope | |
| Eye relief Eye relief How far your eye sits behind the eyepiece and still sees the full picture. On a rifle scope, more distance keeps the scope off your face under recoil. | — |
| Recoil rating Recoil rating How much rifle recoil the maker says the scope can take and still work and hold zero. Makers state it in different units, so compare carefully. | Up to .50 cal |
| Mount Mount How the scope attaches to the rifle: standard rings or a rail clamp, fixed or quick-detach. A good mount does more to hold zero than anything else. | Standard Picatinny rail, no tools; 41.6 mm rail to optical center |
| Ballistic calculator Ballistic calculator Software in the scope that moves the aiming point for distance, using your bullet's data and the range to the animal. | — |
| Zero profiles Zero profiles Saved sight settings for different rifles or loads. Switch profiles instead of re-zeroing when you move the scope or change ammunition. | — |
| Build | |
| Weight Weight How heavy the device is. Check whether the maker weighed it with or without the battery, because brands do it differently. | 29.6 oz |
| Water rating IP rating (water rating) A two-part code for how well the device keeps out dust and water. IP67 means dust-tight and survives a short dunk; an X means not tested. | IP67 |
| Operating temp Operating temperature The temperature range the maker says the device will work in. Batteries lose much of their runtime well before the low end of that range. | -40°F to 122°F |
| Buying | |
| Warranty Warranty How long the maker promises to repair or replace a faulty unit. Check whether it needs registration and whether it passes to a second owner. | 3 years with registration |
| US price US price The price we found for the unit in the US, with where it came from and when. Prices change often, so treat it as a snapshot. | $5,399 |
| MSRP MSRP The maker's suggested retail price in the US: the list price, before any sale. Useful for seeing how good a deal really is. | $5,399Armasight price on armasight.com |
