The SL20 is a small, lightweight USV designed for inland waterway surveying and discharge monitoring. With a 17.7 cm moon pool and ADCP/echo sounder compatibility, it’s ideal for rivers, lakes, reservoirs, and extremely shallow waters. This portable catamaran is commonly used in ADCP velocity profiling, bathymetric mapping, hydrological studies, and dam surveys. The unit’s carbon fiber build, long battery life, and easy-to-carry form make it well-suited for single-operator deployments in remote or urban areas.
