The Retriever System

The Retriever System is the well proven radio-detection system for invisibly marking locations on the ground. A small transponder is buried at the location and is activated and detected by the "Retriever Unit". The Transponders have indefinite life. The system is now widely used throughout the country for long-term monitoring. The Retriever Unit has a Pinpoint mode and we are offering to update existing units to add this feature. The system can also be used for monitoring path erosion or marking archaeological sites.
