100x reflective foil surveying targets reflector target sheets for tunnel

These reflective foil surveying targets are small reflector target sheets designed for use as survey marking points, including in tunnel environments. Each target provides a consistent reflective reference point for survey instruments, helping crews establish accurate readings across a worksite. They suit applications where precise, repeatable measurement points need to be set and identified at a glance.

Each target is made from reflective vinyl with an adhesive backing, giving a bright return of light when hit by a survey instrument's beam, which assists sighting in low-light or enclosed conditions such as tunnels. The wording and markings on each target are printed.

Each target measures 40mm x 40mm.
