Our bathymetry service is used to measure seabed features such as landforms, excavation and embankments, as well as to map riverbeds. We use a dual-frequency HydroLite-Tm echo sounder that combines low frequency (30 kHz) and high frequency (200 kHz) transducers in a unit that allows penetration of soft sediments to detect harder layers and the surface layer.

This uniquely designed tool is useful for classifying bottom types. It allows us to record depths from 30 cm to 200 m with a higher degree of accuracy than the standard system. This tool performs rapid hydrographic surveys in marinas, lakes, rivers, ponds, harbour approaches, around bridge piers, etc. This system allows us to meet the many demands of our clients on their various projects.
