HydraGO
Read full descriptionHide full description
Take soil measurements anywhere for those applications not requiring a permanent soil monitoring system. Your iOS device communicates wirelessly with the HydraGO / HydraGO Flex using bluetooth. Simply insert the probe into the soil, and tap the βSampleβ button in the HydraGO app. The app will display soil moisture content, temperature, conductivity, and dielectric permittivity on-screen for immediate viewing. The date and time of each measurement are recorded along with the soil measurement data and the GPS location measured by your smartphoneβs GPS receiver (HydraGO) or automotive-grade GPS receiver (HydraGO Flex). All data can be saved and emailed as a .CSV file for analysis in Excel. Notes and location names can be added to the data records. HydraGO / HydraGO Flex uses the same patented soil sensor as the HydraProbe.

Verdict
The clearest difference is update cadence: Ruskin at every 4 months against HydraGO's every 24 months. HydraGO's advantage is iOS requirement (9.0 vs 12.0). On price, ads, in-app purchases and device support there is nothing between them.
