The going rate
Priced $140 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, no rangefinder. 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.
