"We have been using the Precis-BX305 GNSS GPS system for unexploded ordnance (UXO) detection projects in Australia, New Zealand and Laos. We have a walking UXO detector with the rover and Precis module receiving GPS corrections and outputting sub decimeter accuracy GPS to our data logging system.

The unexploded bombs need to be detected with an accuracy of less than 20cm, and using the Precis system we have easily achieved this. We are happy with Precis-BX305 GNSS GPS system and its performance. "



"I had my 1st successful flight with a Precis-BX305 mounted on my multicopter logging data. I obtained quality 1 throughout the flight."

"With the Precis-BX305, I produced sub-centimeter results using real-time and post processed kinematic in control surveys. Tersus staff have been friendly, helpful and quickly replaced a faulty part.

The documentation required to operate the system is all available online depending on your experience as there could be a very steep learning curve. I look forward to expanding my business and purchasing newer models from the expanding Tersus range."

 "I am a software developer in Vietnam, and I have worked in Land Survey for 15 years. In the past I have used Trimble GPS, Hemisphere GPS. And Precis-BX305 can be used as GNSS device with professional survey software like HydroPro, HYPACK and routing software in land, sea survey field. It operated smoothly with my system more than I expected."
