Best Features Main Advantages Key Performances
Amazing quality/price ratio Assembling an equivalent solution is costly and time-consuming
- It costs much less compared to an equivalent custom-made solution
Hyper Connectivity Does not require extra components to connect to GSM data network, GNSS, UHF stations, PC, smartphones or tablets without any cables
- Embedded antennas and modems for differential corrections either via UHF or GSM
- Wi-Fi connection for real-time monitoring, data download, off-sets and configuration parameters
Real Time Navigation Display
It does not require bathymetry software unless strictly necessary, in which case telemetry can be achieved in real-time with own software
- Built-in navigation software allows orientating and monitoring in real-time both bathymetry and topography
- Wireless NMEA output allows using other specialized software solutions such as QINSy, HYPACK etc.…
It is extremely precise and versatile
- Accurate GNSS receiver offers enhanced precision at centimetre-level with dual L1/L2 frequency RTK augmentation or at decimetre-level (RTX) with dual frequency L-Band augmentation
- Dual frequency SBES provides a good depth range
- GNSS position accuracy: 1cm
- Echo sounder accuracy :0.2% of water depth
- Dual f. SBES: 200kHz/30kHz provides a depth range between 50cm and 200m
NiMh Battery Safe Battery; no risk of explosion - Up to 10h autonomy with one battery set
- Possibility to add an external battery
Light and easy to carry BALI is a truly portable kit which fits in one small case - Can be assembled in 5 minutes

EXTREMELY ACCURATE• Thanks to its GNSS antenna
BALI offers:• accuracy at centimeter-level
via Real Time Kinematic (RTK) satellite navigation,enhanced precision or,
• at decimetre-level (RTX) with dual frequency L-Band augmentation
• The Single Beam Echo sounder (SBES) provides depth measurements with a resolution of 1cm.
• The dual frequency transducers (f1 200kHz - f2 30kHz) can easily operate with an accuracy of 0.2% of depth.
