I have had the satellite finder for about 15 minutes in use and am only disappointed. The adjustment of the antenna is simple to the receiver, and faster without these annoying high-pitched tone, provided you have the satellite found "gross" (which also has to be, otherwise you should anyway an expert left). But maybe this helps Satfinder one or the other when the alignment on the roof, far away from the receiver takes place (for me it was on the balcony, about 4m from the receiver), so I can also imagine and not a second person on receiver which receive data transmitted saves the cost of the unnecessary toys. Therefore, from me a star, because less is unfortunately not.
