Soft mud deposits are increasingly encountered around the world, from natural offshore deposits and mud layers in estuaries, ports, and waterways to progressively growing leftover from treatment and extraction facilities, mines, and oil refineries. Reliable monitoring of the temporal and spatial strength buildup in such deposits is crucial to optimize their sediment management plan. In this study, two well-established shear strength profilers i.e. GraviProbe 2.0 (dotOcean) and RheoTune (Stema Systems) are investigated. Their working principles are described, and their performance is compared against direct strength measurement. Finally, capabilities, limitations, and points of improvement of both instruments are discussed. @en
