What Water Utility Professionals Say About Eos

Elisabetta DeGironimo

 “Well we have received the Arrow 200 unit. It is awesome! It’s the easiest to configure GPS receiver that I’ve used in my 20+ years of GPS data collection.”

Elisabetta DeGironimo

GIS Coordinator, Mohawk Valley Water Authority / NY, United States

Kenny Ratliff

“Compared to the collection equipment cost in 2013, the Arrow Gold comes in around half of that. The best part is – there is no accuracy loss.”

Kenny Ratliff

GIS Manager, Oldham County Water District / KY, United States

Travis Anderson

“I felt like we finally had the last piece to our puzzle. The days of waiting 30 seconds to get a point were over. Points now come as fast as you can tap the buttons.”

Travis Anderson

District Engineer, Le-Ax Water District / OH, United States

Nathan Ward

“It’s one thing to put points into a GIS. But you don’t want to have to go out and map them again. That’s where having the Arrow Gold+ is so helpful. It brings the confidence to know that our valves are now very accurate.”

Nathan Ward

Director of Engineering, Cassatt Water / SC, United States

Ronald Stith López

“If our RTK connection is lost, the Arrow Gold maintains our RTK corrections thanks to the SafeRTK feature.”

Ronald Stith López

Technical Cadastral Coordinator, Conhydra S.A. / Lima, Peru

Theresa Lancy

“Because the cost and effort involved was fairly minimal, it just made a lot more sense to go ahead and set up our own base station. We also thought there could be other groups in the city that would use this system.”
