Map Scale Lock ArcGIS Pro

[eyohannes]

I'm trying to lock the scale at 1:807,794 so that I can navigate across my map to different Residencies of Virginia with the same zoom level. 

Is there a way to lock this scale?

You can set a fixed scale for map frames in layouts: Map frame constraints—ArcGIS Pro | Documentation

For working in the actual map, you can utilize a custom scale:

´Then you can pan (and zoom)  to a differnet part of your map and select your scale from the scale list:

If you only want to see your custom scale, you can delete all other scales from the list...
