Our receivers can measure field strengths that vary greatly in magnitude, from weak, naturally occurring magnetotelluric signals to strong CSEM signals. And, highly precise signal timing enables us to measure the EM phase with respect to the source.

For accurate seabed positioning, the receivers are designed to descend rapidly; to enable large surveys to be performed, they can remain autonomous for weeks.

So that we can perform large and efficient surveys, we have invested in not only receiver technology but also purpose-built 3D EM vessels, which are designed to handle large numbers of receivers efficiently.
