The VH400 doesn’t measure conductivity. Sounds like that’s a good thing. Since it can be buried the moisture differences between drippers can be mitigated pretty well because the water will spread out once it enters the soil. I definitely agree that the position of the sensor is important, so point taken there.
However, I’d much rather measure soil moisture directly than try to predict it with alternative measurements.
