To expand a bit, Geosphere has the ability to display the proximity circles as an overlay on the map, and it's also set to only show on physical waypoints - posted coordinates for physical cache types, and multi-stage and final waypoints. (reference points, parking/trailhead/virtual etc are not relevant for proximity concerns and so don't show the circle). It's a very useful feature, especially when planning for cache placement in a busier area.
