Not necessarily true. I'm not sure about PMR's, but I know that the Reloader B doesn't pickup the sound of some markers firing. In my opinion, break-beam eyes are the safest option. They will only get dirty if you get a smeg in your loader, which happens very rarely and mainly with crappy paint.Halo B or Reloader B. They both look nice and have the same speed. The only difference is the Reloader B is sound activated which i prefer and think is better. Once it hears the gun it knows to start feeding.The Halo B uses eyes that activate the hopper, once balls pass it, it starts to feed.
With sound you cant go wrong, its good. (Reloader B)
With eyes ,the eyes can get dirty and not know when to feed. (Halo B)
With sound activated, theres less to go wrong.
Go for the Empire Reloader B in my opinion
