They are not putting it on their website until they have them ready to Ship which will be the first week in September. Once you see it on their website then you can order. Cost $95. The enhancements will not effect its range or accuracy. The sensor is the same or better they just modernized the display and chipset. I should recieve my pre-production model Wed or Thu and be testing it this weekend. They have worked closely with the origional designer the keep it as good or better than the origional.
