How this list is ranked
- Identification distance: the farthest a coyote still stands 12 pixels tall on the screen, enough to tell it from a fox or a dog. Calculated from the maker's sensor and lens.
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.
- Then field width: on a tie, the one that shows more ground at 100 yards, so you find animals faster.
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.
- Then price: on a further tie, the cheaper one.
Only current models sold through US dealers with a published US price. Nobody paid for a spot, and affiliate links never change the order. The coyotes are drawn at 200 yards, one square per sensor pixel, all on the same scale. How we measure.

What is left out
Discontinued models, which sell used on eBay; brands with no US dealer network; and models whose maker publishes too little about the sensor or lens to calculate a distance. All of them are on the thermal monoculars page.
Prices are the US price on file for each model, or the maker's list price where marked MSRP. Retailers change them often; the retailer's page is the current one.
