Identifies a hog at 150 yd26° apparent FOV — how big the view looks
The InfiRay RICO Mk2 640 LRF 3x 50mm ranks #17 of 80 640-class scopes on image: priced above the class middle without the image to match — the chart below shows scopes with more picture for the money (image 75, class median 73; $4,499 against $3,994). The same InfiRay core sits in the Nocpix SLIM H35 at $2,499 — the extra $2,000 here buys the 50mm lens and the rangefinder.

The going rate
Priced $1,284 over the going rate for its build.
Every dot is the street price of a scope built like this one — same sensor class, a similar lens, rangefinder built in. The part of the price above the rate is buying body, screen, and name — not the spec.
Each dot is a 640-class scope: image score up, street price across, dot size = objective lens. The shaded corner is the best-value zone — the most picture for the least money. This scope is outlined in black.
Through this scope, for real
Recorded through the InfiRay RICO Mk2 640 LRF 3x 50mm by reviewers and owners. Video compression softens the picture — the eyepiece shows more detail than the upload.
