We currently have the standard windshield mount mirror that comes with the Mobius LSV. It works OK, but there are a couple things I don't like about it. First, we have to remove it when trailering and/or putting the cover on the boat. Second, the field of vision isn't wide enough to see the wakeboarders when they cut way out on the sides. So, I am looking at a tower mounted Extreme mirror. There appears to be two companies with this mirror. The mirror itself has three mirrors (lenses), the middle lens is 12" x 6" and is fixed, while the two end lenses are 4" x 6" and adjustable. This allows you to see the wakeboarder even at the extreme edges in the mirror. The only negative is it appears the mirror costs approx. $250 plus shipping. Does anyone have any experience with these mirrors and are they worth the money?????
