Completing an InfoPath form offline?

I am very VERY new to the InfoPath (in fact this is the first task I've been given). We have livestock farms where there is no internet connectivity. Our farm managers need to be able to complete a form using a tablet device and submit the data (which I assume will be stored locally), then when they get back to an area with connectivity, the form will upload to our SharePoint library.

What I have done so far. Create the form template in InfoPath. I have published it to SharePoint and selected the relevant offline settings in Form Options (as per attached screenshot).

When I go to my document library in SharePoint, I can click New->Form and I am presented with the form that I can complete and submit. The completed form shows up in the same document library.

Now how do I get this onto their tablet so that they can complete it offline? (I do have InfoPath Filler installed on the tablet).

Thanks in advance.
