Published range conditions — every model, verbatim

47 rangefinder models, each with the manufacturer's own test condition beside its range figure. This is the table that makes range numbers comparable: target size, target reflectance and visibility, exactly as published — not paraphrased, not extrapolated.

Why this table exists

A "maximum range" without a target is a marketing number. Two modules both claiming 12 km can be measured against a 5 × 15 m vehicle in 23 km visibility and against a 0.5 m drone in 6 km haze — a factor of several in real performance. If a supplier will not publish the condition, treat the figure as decoration.
