In the field with the FieldScout Mobile app

The FieldScout Mobile app collects and displays data from the FieldScout® TDR 350 soil moisture meter instantly over a Bluetooth Smart connection, with live readings on any Bluetooth Smart Ready smartphone or tablet:

  • Color coding shows a scale of moisture, EC, surface temperature or turf firmness
  • Relevant information can be e-mailed to share results with others
  • Free download from the Apple App Store or Google Play (Android)

Pro Mode, available with a SpecConnect subscription:

  • Readings are overlaid on your property on a dynamic Google Maps satellite image
  • Guided Mode takes grid readings without you touching the phone
  • Freeform Mode plots one point per reading and keeps its data separately
  • Data is uploaded wirelessly and automatically to SpecConnect for further analysis from your personal web portal
  • No computer, cable or GPS accessory is needed
  • SpecConnect gives a complete overview of the data at once, overlaid on a satellite map
  • Color gradient mapping of data points within areas or groupings you select
  • Data can be exported from SpecConnect to an Excel document for deeper analysis
