Compact and self-contained, BALI is an easy-to-operate, single-rod bathymetric measurement system. This lightweight bathymetry kit combines a single-beam bathymetric echosounder with a RTK GNSS receiver. It processes and stores water depth measurements synchronized with a georeferenced position with centimeter-level accuracy, even in difficult areas.

Ultra-portable and easy to set up by a single operator. The kit includes 2 cables and 3 poles, it is quick to assemble and can be easily carried in its case. Bali’s built-in NiMH battery provides up to 10 hours of use.


The smart antenna is integrated with all the necessary telecommunication equipment to ensure a high level of connectivity to different types of radio networks: 3G, UHF and Wi-Fi.


Real-time monitoring and wireless remote control is possible by connecting a PC, tablet or smartphone to the Wi-Fi access point integrated in the kit.


GNSS and UHF/GSM technologies are directly integrated into the antenna and allow to carry out surveys with real-time centimeter-level accuracy (RTK). The echosounder provides depth measurement with an accuracy of 0.2 %. Its transducer with an integrated temperature sensor adjusts the measured water height in real time.

Easy to use

Hydrographic operations are very intuitive. No PC or hydrography software is required, a simple Smartphone is needed to connect via Wi-Fi to the internal web server.


The nickel metal hydride (NiMH) battery is known to be much more stable than lithium ion and is safer to store and transport.
