I'm in the market for a new sight too and just looked at the Cosmic Lite at their website. It looks like it would be very bright but can somebody explain the one pin to me. Do you have to adjust the sight on the side for distance before each shot at a different range? It seems like it would be more involved than just having more pins for different ranges. Plus I have enough stuff running through my mind when the deer appear I'm not sure I would remember to adjust it.

Can somebody explain exactly how to use it and its advantages?
