Does the Echo Meter Touch log the GPS location of the recordings and my path?
The Echo Meter Touch does log the recording location if you have an iOS device that includes GPS functionality. Any iPad that is cellular-enabled (and of course the iPhone) will log both GPS locations and path. If you do not have GPS, you can purchase a Bluetooth GPS module that will stream location data to the iOS device. There are several such devices on the market, including the Dual Electronics XGPS150A and the Garmin GLO. Both are under $100, highly accurate and have their own batteries to avoid depleting the iOS device. If you have built-in or Bluetooth GPS, then all the recordings will be tagged with their location and the path will be recorded from each recording session. The path and locations are also exported with recordings in KML format and can be opened in Google Earth.
