Our survey boat is well equipped with the latest Hemisphere GPS 200 Series that guarantees sub metre accuracy in satellite positioning and Hydrobox Echo Sounder that gives millimeter accuracy in depth measurements.

 Tide gauges and current meters guarantee proper hydrographic data acquisition while our hypack hydrographic survey software enables digital computer aided designs of dredging project sites like digital terrain models, seabed models of navigation channels/canals and sand stockpiles to be precisely reproduced on plans and maps to scale. Accurate Quantity determination of dredged material which is vital in costing is also ensured with this software.
