Description
Figure 10 shows the RiverSurveyor system with wireless communications, in this case Blue-
tooth, using a small unmanned boat, such as the SonTek Hydroboard. The maximum range us-
ing the supplied Bluetooth dongle plugged into a PC is up to 200m. The Bluetooth range of the
Mobile device is approximately 60m. Those approximate ranges assume a clear line-of-sight
with no obstructions or inclement weather.
