Mount Sopris Instruments donated a 2PGA-1000 Poly Gamma probe to the EEGS Foundation, a 501(3)c charitable organization chartered to encourage the use of geophysical technologies to solve the near surface problems of today and tomorrow. The 2PGA tool provides natural gamma, spontaneous potential, and single point resistivity data in a compact body, able to function in boreholes as small as 2″ in diameter. It has been the cornerstone of the Mount Sopris Poly probe family for many years. You can find more information on the EEGS Foundation at
