Overview
Oceanalpha SL20 Hydrographic ASV is designed for water discharge measurement and hydrographic surveys. The SL20 ASV is compatible with different brands of Acoustic Doppler Current Profilers (ADCP) and single beam sonar, such as Teledyne RD Instruments' Workhorse Rio Grande, RDI, SonTek's RiverSurveyor S5/M9 ADCP, and LinkQuest's FlowQuest ADCP.

The SL20 ASV weighs only 12kg weight which makes it maneuverable, compact, and easily handled and operated by one person. It is also small enough in size that it can easily fit in the back of an SUV or trunk of a sedan. Capable of reaching a maximum speed 5.5 m/s (10.7 knots), and observable within a 2km communication control range, the SL20 ASV is suitable for most water current environment.

SL20 ASV is specially designed for hydrographic surveying and bathymetric measurement. Its optimised unmanned vessel style reduces the impact of water current on voyage and noise on the measuring instruments to the maximum extent.

SL20 ASV is made of carbon fibre and fibre glass with anti-corrosion, anti-wave, low temperature resistance properties, and is mounted with two propellers to avoid aquatic plants and garbage twining.
