This baby is a 100-meter Bluetooth adapter with lithium battery.
According to the actual test, the maximum distance is 124m. This data is for reference only. The wireless communication is also greatly affected by the environment. For example, there are interference sources such as high-voltage lines around, and the transmission distance is greatly reduced, and communication is even impossible. Another warm reminder: Do not use the total station under high-voltage lines.Total StationThere is a risk of burning out when working in a strong magnetic field. This has happened in actual cases!
