Abstract

In the middle of the last century, surface multiturn coils and quartz variometers served as sensor components of the alternating magnetic field. Later, they were replaced by fluxgate sensors measuring the alternating magnetic field against its constant component and induction sensors reacting only to the variable component. Thanks to a wide frequency range and a low level of generated noise, induction sensors became the main instrument, converting alternating magnetic field into an electric signal. However, there are significant difficulties when it comes to their installation at survey sites, particularly for the vertical component (Hz). This process is first of all, very labour intensive and, second, at times simply impossible due to local conditions, such as rocks, slopes, sand, snow and ice. A solution has been found in utilizing custom designed tripods, which are used not only to accurately align the sensors but to also easily transport them. These are currently mass produced and easily accessible on the market. In recent years, many successful mining geophysics projects have been completed with both geological and economic success in large part due to the use of these tripods. In some cases, these projects were only possible as a result of tripod application since they allow carrying out successful field surveys with AMT, MVP and CSAMT methods on any terrain and soil conditions.
