AGM Rattler V2 35-384 vs ATN ThOR 5 LRF 640 3-24x
Both put about the same number of pixels on a coyote, 18 tall at 100 yards, so neither sees farther. You can tell a coyote from a fox out to about 150 yards with either.

Calculated from sensor and lens
What a coyote looks like on each
The sensors are 384 and 640 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.

Key differences
- Both put about the same number of pixels on a coyote, 18 tall at 100 yards, so neither sees farther. You can tell a coyote from a fox out to about 150 yards with either.
- The ThOR 5 LRF 640 3-24x shows 68% more ground side to side: 66 feet at 100 yards against 39. Wider finds animals faster; narrower shows each one bigger.
- Only the ThOR 5 LRF 640 3-24x has a rangefinder (1,000 yards).
- Only the ThOR 5 LRF 640 3-24x has a ballistic calculator.
- The Rattler V2 35-384 costs $1,450 less at current US prices ($1,745 against $3,195).

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.
