EchoLogger

EofE Ultrasonics was founded in 2009 and operates the EchoLogger brand from Goyang. The company develops acoustic transducers, compact electronics and control software across single- and dual-frequency echosounders, scanning sonar and three-dimensional imaging systems.

The portfolio is designed for integration as well as standalone survey work. Autonomous altimeters can support vehicle clearance and navigation, while boat and USV kits combine sonar, GNSS and logging for bathymetry. Deeper-rated configurations extend the same sensing role to underwater vehicles and long-duration monitoring, making EchoLogger an enabling perception supplier rather than a marine-robot builder.
