Down Under Surveys (DUS) although an Australian company, we are so named because we carry out below ground acquisition of geophysical data. This is achieved by lowering the applicable probe down an exploration drill hole and logging radiometric or other specified data. We can go to depths of 2,000m with our 4 conductor winch. Our other winches have cable lengths of 450m and are used primarily for Uranium exploration and in the iron ore. The natural gamma probes use for Uranium exploration have been calibrated at South Australia's Department of Water, Land and Biodiversity Conservation by Geophysicist David Wilson under the supervision of CSIRO. Our other Natural Gamma probes are more sensitive and are used for determining shale bands and other rock layers.

We are closely aligned with Navaids, a GPS consultancy company that conducts GPS surveys for many Exploration and Mining companies in Australia and overseas. Our main focus is mapping drill hole collars, setting out accurate grids and establishing survey control for applications such as Aerial photography. Exploration Lease pegging is also available.

Our field crews are well trained and have years of experience in the mining industry. Personnel have current MARSTA and Senior first aid training. The crews are equipped with a satellite phone, EPIRB, UHF radio and First-Aid kit as standard. All vehicles have a tool kit to repair and test equipment in the field. Our logging equipment is the latest available and is thoroughly checked before each project. We have an Electronics Engineer and support staff at our Perth office.
