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. Models are available in 2.5 Hz or 5 Hz frequencies. The 5 Hz model is a great all-around instrument for grounding and reconaissance surveys. The 2.5 Hz model takes a little longer for the readings (because of the lower frequency rate) but is capable of larger "a" spacings - out to 1000 feet!
