THSP75 mini prism and target holder
A small tripod that holds a mini prism or the included reflective target over a survey nail, so you can backsight on your own without a robotic total station or a survey assistant.
The THSP75 sits the prism or reflective target much closer to the survey nail than a traditional tripod, which makes placement more precise and means you don’t need a tripod at all for backsights. It’s ideal for topographical surveys and setting out.
The holder takes a standard mini prism with a 12 mm spike. You can adjust it three ways to set up quickly over a nail, using either a mini prism or the included reflective target at a height of 75 mm.
