GRT-100 This gamma ray tool is housed within an in line GO body. The GRT-100 has been designed to run on the end of a GeochainSlimTM tool string. However as the tool is through wired it can also be used in conjunction with any compatible monocable tool string.

The GRT-100 is connected immediately below the STAS. The STAS transmits the gamma information to the surface digitally with all other status information in Geochain Slim’s Monitor mode.

Surface Control –The Geochain System Panel (GSP) with an inbuilt Gamma Control Module (GCM) is required for all gamma tool systems.
