Abstract: Techniques are disclosed for precisely locating and marking placement locations for drilling or conduit installation in construction environments. A pipe conduit locator system includes a focused-light system disposed within the housing and a clamping mechanism having a plurality of prongs configured to engage with a hollow surface. The focused-light system projects light towards a target location and the clamping mechanism moves between an open position and a closed position. A clamping mechanism secures the system to an elongated body, ensuring stable alignment during operation.
