Tracking arrow flight.
To answer your question; The Zeon Vanes are indeed 'cool looking vanes', but there's not much difference tracking the flight of the arrow when fletched with the Zeon vane as against using say a Blazer, VaneTec etc.
If your purpose is the track the flight of the arrow or to find your arrow after the shot use a 'Firenock'. By no means cheap, but will get the job done.
