Abstract: A system designed to identify survey markers that are obscured by an accumulation of dust and dirt or overgrowth of vegetation. The system provides for automatic detection of survey markers using passive radio frequency transponder technology to detect the immediate presence of a tagged survey marker and read additional unique identification data corresponding to said marker. The operator can be signaled audibly and/or visually when a tagged survey marker is detected. The transmitter and antennae are mounted in a handheld or portable unit. An integrated microprocessor performs the requisite algorithms needed to process the reply from one or more RFID (Radio Frequency Identification) tags and generate the alert signals for the operator alerts. Once the RFID tagged survey marker has been located, it can be cleared of accumulated dust, dirt and overgrowth of vegetation to make it visible for confirming the property boundary.
