These were originally designed to sample for minerals in beach sands but are now used extensively for drilling and sampling in very sandy friable soils. A 75mm diameter sand auger will penetrate 30cm in about 4 turns, which fills the auger.
In good conditions, one man can drill 10 metres in an hour.
