Does anyone have any tips for the best device for collecting data in the field.? Tablet a bit fiddly - any particular models that you’d recommend?
Hey Catriona!
Welcome to the user community 
We’ve got some documentation on this topic here: https://documentation.networkcanvas.com/how-to/choosing-hardware/
Are there specific questions you have that aren’t addressed there?
In general, my advice would be to use a Windows laptop with a touch screen, since you’ll get the best part of the tablet experience without the hassle associated with the platform.
