Customer Testimonials:

![The University of Arizona]()
"I like these probes because they have given us good reliability and have been out in the Arizona heat for almost three years, with little or no trouble. The ability to make a single insertion and get distinct soil moisture profiles, i.e., 0-30 cm, 30-60 cm, etc., has given us the advantage of minimal soil disturbance while getting reliable soil moisture values."
Edward C. Martin, PhD Professor & Extension Specialist Dep. Ag. & Biosystems Engineering Maricopa Agricultural Center

![EWING]()
"This is what I openly say to not only my customers but also to NRCS engineers and other interested parties: 'I believe that the GroPoint sensor provides the best value to my customer because of its accuracy, reliability and the fact that it requires no additional maintenance or calibration once installed.'"
David Bower Branch Manager Ewing Irrigation

"The instrument receives a fair amount of 'abuse', being carted over logging slash, through salmonberry and other brush vegetation and has been used in the rain. However, it has been rugged and reliable. The measurements generated are believable and repeatable and nicely relate to patterns of precipita-tion occurring at the site."

![Monterey Pacific]()
"I have used GroPoint sensors and dataloggers to schedule deficit irrigation over thousands of acres of premium winegrapes since 1999. The data on soil moisture status has proved accurate and consistent during and between seasons. Importantly, running a network of 80+ sensors over this time, I have had only 2 sensors and one logger fail from non-mechan-ical causes. I also have a network of (competitive) loggers/sensors, which demonstrated a 15-25% failure rate in the first 2 seasons."

![NM State University]()
"The alternative to [the GroPoint Profile] is trenching with horizontal insertion of numerous (short) probes. The effort of trenching alone is a deterrent, and the disturbance of soil and root systems is yet more of a deterrent. I find it difficult to fathom why a research-er would use this alternative."
