Borehole Antennas / BA-series


Geoscanners is one of the rare GPR manufacturers who provide solutions for borehole surveying. All of the borehole antennas in our product line are extremely slim (38mm in diameter), making the BA-antennas ideal for vertical and horizontal boreholes of relatively small diameters. The antenna connectors are devised specifically for the BA antennas to guarantee water tightness. This, together with the extra strong cable, allows for unpredicted jams to be resolved by a simple pull.

In addition to the conventional borehole surveys, the fact that the BA antennas are water tight allows them to be used for river and lake bottom profiling. All antennas from the BA-series are equally reliable and provide high quality data.
