Survey Range Finder

A survey-grade range finder with tripod socket, baseline memory, and enough optical filtering to work around welding arcs and hard starlight. It measures distance cleanly; building a trustworthy site grid still takes repeated stations and a competent operator. Stored points include coordinates and timestamps, so a borrowed unit may reveal where the previous crew spent its quiet afternoon. Praxis recommends a bench check after hard use; skipped certificates are cheap until an insurer asks for the last valid one. Praxis will recertify a transferred Survey Range Finder, but the bench fee climbs when its shock log has gaps. Salvagers call that extortion right up until a claim depends on the number.
