Exploranium GRS-101A Portable Gamma Ray Scintillometer
The Model GRS-101 Total Count Scintillometer is a complete field system designed for man-carry applications requiring accurate and reliable determination of gamma ray intensities from radioactive elements. This is a vintage electronic machine, that I purchased off an old B.C. Geologist, that is battery powered and appears to work. Priced at $425 plus $28 shipped in the flat rate box including tracking and insurance. GRS and myself located in Vancouver B.C.
