The SinoGNSS HYD10 is a portable, IP67-rated single-beam echo sounder weighing about 1.2 kg, using a 200 kHz transducer to measure depths from 0.3 to 200 m at roughly 1 cm accuracy. It connects to an RTK receiver and mobile device over WiFi and Bluetooth and pairs with ComNav's Survey Master software to combine real-time positioning with depth logging, giving field crews a lightweight, largely cable-free hydrographic survey tool.
