Sediment echosounder

The iXblue and Knudsen range of sediment echosounders perform high-resolution sediment measurements under the seabed. The equipment can operate in shallow and medium depths using very low frequency acoustic technology (CHIRP 5 to 15 KHz). Their compact size allows for easy integration on all types of vessels for measurement of seabed sedimentary layers and buried object detection.
