The present invention provides a land surveying assist device, which can be remotely controlled on command for path alignment. The device includes a receiver for receiving beams of energy, such as infra-red energy, from a remote transmitter source in the field. The device further includes a servo mechanism to rotate the device on-command to achieve alignment with the incoming beam path from the remote transmitter. Alignment is achieved when the incoming beams are reflected from the device back to the remote transmitter source, at which time the servo mechanism is deactivated.
