To detect a laser beam, a battery powered electronic sensor target, also called a receiver or ___, is attached to the leveling rod.

To detect a laser beam, a battery powered electronic sensor target, also called a receiver or ___, is attached to the leveling rod.

• A. Receiver
• B. Sensor
• C. Detector
• D. Monitor

Answer: (C)

In a laser leveling setup, the device attached to the leveling rod is focused on sensing when the laser beam is present and converting that signal into a usable height reading. That sensing function is best described by the term detector. The detector, or laser detector, is a battery-powered electronic target that picks up the beam and indicates the rod’s height accordingly. A detector emphasizes the action of detecting the beam itself, which is the key role in this tool. While a receiver conveys the idea of getting the beam, the word detector specifically highlights the sensing function, making it the most precise fit. A sensor is a broader term for any sensing element, monitor suggests watching over something rather than detecting a beam, and a receiver is already used in the prompt, making detector the natural completion.
