it removes the eyes from a revi and replaces them with a microphone so the hopper reacts to the sound of your marker fireing....works very well im told
Re-loaders work really well. I've got the upgrade kit in my revi, and have to confess I now prefer to run the re-loader over my Z-board eggy or my halo.
Yes, there is a loss in speed but nothing that you can't compensate for most of the time. And the Vision eye takes care of the rest. Very light and compact like a revvy but acts much like a hard wired intellfeed.
