I noticed with unusually shaped enclosures and path layout it gets pretty hard to cover more than one enclosure. I can see this being a bit of a bigger problem with the larger enclosures.
It would be nice to see the range increased a bit to be able to cover a little more area to be available to accommodate more than one enclosure at a time.
The range on the small and large are the same, for the large it makes sense it would have a much larger range to cover the larger enclosures.
