THSM20 magnetic reflective targets
Reusable reflective targets with a strong magnet inside, so you can fix a target to steel in seconds, wet or dry, and take it away again when you're done.

Sticking targets to metal is fiddly at best and impossible when it’s wet. The THSM20 has a strong neodymium magnet inside, so it holds firm on steel and can be reused job after job. It’s useful wherever you’re working with a total station: measured surveys, setting out, topographical surveys and structural monitoring.
They’re made for surveyors who want to use fewer stickers and place targets more consistently around a site.
