Updating features in the field accuracy issue (TerraSync)

My workflow involves going from TerraSync to Pathfinder Office to ArcMap.

Data is accurate and it works for me.

Now that I have features collected in ArcMap, it is time to go back out in the field and update them.

 

Here's where I've run into a problem.

 

In ArcMap, I export the features that I want to update as a Shapefile.

In Pathfinder Office, I use the "Import" tool to convert that Shapefile to a ".imp" file. (I've matched up Coordinate systems already)

Still in Pathfinder Office, I then use the "Data Transfer" tool to send the ".imp" file to my Trimble Device.

Using TerraSync on the Trimble Device, I can open the ".imp" file and view the features that I want to update.

However, the features are not accurately located on the device.

Averagely, the feature location on the device is about 20 meters away from where it should be.

 

From what I can tell, data is accurate up the point of being opened on the mobile device.

I am still new to GIS, figuring things out as I go.

Does anyone have an idea as to why my Features are 20m off target, only on the device?
