Grounding Surveys Ultra MiniRes

The Ultra MiniRes is the third model in the MiniRes line and the most recent. It is likely the most accurate resistivity and IP field instrument available today. This 2.5 Hz model is a great all-around instrument for grounding and mining reconaissance surveys. At 2.5 Hz, it takes a little longer for the readings (because of the lower frequency rate) but is capable of larger "a" spacings - out to 1000 feet! The accuracy and repeatability have made the Minires a favorite for those working soil resistivity surveys for grounding of power and pipeline protection systems.
