The PSO-1-1 Scope is a weapon attachment in DayZ Standalone. It is has a 3.6x magnification, an inbuilt rangefinder for 5'8" (1.7m) targets at 100m-400m, and a single central chevron as the primary aimpoint. Unlike most optical attachments, the PSO-1-1 Scope zeroes in increments of 50m, from 100m to 400m.

The PSO-1-1 Scope consumes 0.02 energy per second and therefore consumes one battery every 42 minutes of active use.
