High Resolution Optical Depth Encoders Dynamic Electronic Braking System Emergency Hand-Brake Automatic Level-Wind Industry-Standard, Lightweight, Small Footprint, High Capacity Winch
Mount Sopris Equipment Details MGXII Console Software configurable power supplies Support for many third-party probes Dust, water, and shock resistant case Universally configured depth-measuring system Interface digital and analog tools Stand-alone depth display
Caliper 2PCA-1000 Caliper Probe Use to determine well diameter Simple yet very useful log for identifying fractures, physical well construction details
Gamma & Resistivity 2PGA-1000 Probe (Natural Gamma, Self Potential, Single Point Resistance) & 2PEA-1000 Poly Electric Probe (Normal Resistivity) These logs run together on the same as one tool Useful for identifying formational changes
Normal Resistivity 2PEA-1000 Poly Electric Probe The Mount Sopris 2PEA-1000 PolyElectric probe and the 2PGA-1000 PolyGamma probe combine to make a multi-parameter probe. The totally digital probe combination measures 8, 16, 32, and 64inch (0.2, 0.4, 0.8, 1.6 meter) normal resistivity, single point resistance, self-potential, and natural gamma.
Sonic Log 2SAA-1000/F Full Wave Sonic Probe Used to determine formation density Often used in the water well industry for determining well grout location during grouting operations
