2450GR Operator’s Manual Overview - 4 Overview Item Description Notes 3. Antenna Digital radar transmitter/receiver that uses two frequencies to detect buried pipes. The 2450GR scans and records both frequencies simultaneously at all times. High frequency (700MHz) has shallow penetration. Best in conditions with good radar conductivity, such as ice, sand, concrete, or rock. Low frequency (250 MHz) has broad, deep penetration.
2450GR Operator’s Manual Overview - 5 Intended Use Intended Use The 2450GR is a ground penetrating radar system that detects metallic and non-metallic pipes and cables buried underground. Following standard radar principles, the 2450GR uses a high performance electromagnetic sensor equipped with electromagnetic transmitters and recievers to identify underground utilities and transmit the location data to a portable computer where specialized software maps the location site.
