Calculated from sensor and lens
What a coyote looks like on each
The sensors are 4000, 3840 and 1920 pixels wide. How many pixels land on the animal comes from pixel size and lens length, not from the sensor's size. Here is a coyote at each distance, drawn with the pixels each unit would give it. Every square is one sensor pixel, at the same size throughout.

Telling a coyote from a fox at night
Digital night vision
A camera-style sensor that sees in very low light and in infrared, usually helped by a built-in infrared light. Cheaper than tubes, and it shows color by day.
On digital night vision the infrared illuminator, not the sensor, decides how far out you can name an animal at night, and makers rarely publish how far it reaches. In good light the pixel math above runs to hundreds of yards, which is why we do not quote a yardage here. Hunters report roughly 120 to 300 yards at night, depending on the illuminator.
Ground across the screen 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.
At base magnification. Wider finds animals faster; narrower shows each one bigger. You cannot have both from one lens.
Key differences
- Most pixels on a coyote: the Wraith HD 4-32x50, 112 tall at 100 yards.
- Widest view: the Wraith 4K Mini 2-16x32, 40 feet across at 100 yards.
- Longest runtime: the Wraith 4K Max 3-24x50, 8 hours.
- Lowest US price: the Wraith 4K Mini 2-16x32, $700.

| Resolution Sensor resolution How many heat-reading pixels the sensor has, such as 384 × 288 or 640 × 512. More pixels show more detail, but the lens matters just as much. | 4000 × 3000Better | 3840 × 2160 | 1920 × 1080 |
| Refresh rate Refresh rate How many times per second the picture updates. 50 or 60 times a second looks smooth; lower rates stutter when you pan or a coyote runs. | Not published | Not published | Not published |

| IR illuminator IR illuminator A flashlight of infrared light that people can barely see or not see at all. Digital night vision depends on it in the dark, and it often limits how far you can see. | 850 nm, in the box, detachable | 850 nm, in the box, detachable | 850 nm, in the box, detachable |
| IR power 850 nm vs 940 nm IR The two common infrared light colors. 850 reaches farther with a cleaner picture but shows a faint red glow; 940 is close to invisible but reaches less far. | 2,500 mW | 1,060 mW | 1,060 mW |

| 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. | 60 mm f/1.2 | 50.3 mm | 80 mmBetter |
| 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. | 3× | 2× | 4× |
| 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. | 24× | 16× | 32× |
| 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. | 6° wide | 7.62° wideBetter | 4° wide |
| Identification, zoomed to full sensor (calculated) Identification distance Our estimate of how far away you can tell a coyote from a fox or a dog. It is calculated from the lens and sensor, assuming good conditions. | ~1,945 yd in good light | ~1,470 yd in good light | ~1,400 yd in good light |
| 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. | 300 yd | 300 yd | 200 yd |
| Display | |||
| Display Display resolution How many pixels the small screen inside the eyepiece has. A sharp screen looks cleaner but cannot add detail the sensor did not capture. | LCOS 1280 × 720 | FLCOS 1280 × 720 | FLCOS 1280 × 720 |

| 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 | No | No |
| Video Onboard recording (storage) Built-in memory that records photos and video of what you see. Useful for reviewing shots and sharing hunts; listed in gigabytes. | 4K | 4K | 1080p |

| 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. | 69 mm | — | 60 mm |
| 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. | .308 | .308 | .308 |
| 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. | Fixed Picatinny mount included | Fixed Picatinny mount included | Fixed Picatinny mount included |
| 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. | 4 | 5 | 5 |
| Build | |||
| Weight Weight How heavy the device is. Check whether the maker weighed it with or without the battery, because brands do it differently. | 34.6 oz | 21.6 ozBetter | 36.3 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. | IPX5 | IPX6 | IP55 |
| 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. | -4°F to 140°F | 32°F to 140°F | 21°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 | 3 years | 3 years |
| 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. | $700 | $700 | Discontinued |
| 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. | $700 | $700 | $500 |

How the numbers are worked out. Each pixel covers an angle equal to pixel pitch divided by focal length. A coyote is drawn to scale, 36 inches nose to tail base and about 22 inches at the shoulder. Identification uses Johnson’s criteria: about 12 pixels across the animal’s smallest dimension, here shoulder height. That lands where hunters report it, around 150 to 200 yards on common units. Digital zoom makes the picture bigger but adds no pixels, so it changes none of these figures.
