Wireless Connection
Achieve connection with the receiver via cable or Bluetooth.
Thermal Protection
No longer worry about the effect of temperature on the power, for the TRU35 can adaptively adjust the transmit power, automatically reduce the power when the temperature is too high, and increase the intensity when temperature decreases to ensure the TRU35 is always in a stable power range and will not be damaged by overheating.
Convenient Configuration
Directly configure the TRU35 by SurPad software, independently developed by eSurvey GNSS, via Bluetooth, including its mode, protocol, baud rate in the air, frequency, and power level.
Standing Wave Detection Protection
No longer worry about damages caused by a long-time open circuit or short circuit.
Over Voltage Protection
With the two-stage surge protection, no longer a need to worry about damage to the TRU35 when the input voltage or current exceeds the normal range of positive and negative stages are reversed.
Long Transmission Distance
The transmission distance can reach up to 14 km with high power operating under optimal conditions.
