Hi, Doug (I've been wondering were you've been) > But I am guessing the unit really "listens" to the satellite for info on > where it is, Right on. The Scout maintains an 'almanac' so it knows where and what satellites are overhead (well, above the horizen). It has a display that gives the direction and altitude (in degrees) of up to eight satellites. It will track the 6 best signals, switching sats. as required. BTW, The first time a Scout is turned on it takes 12-15 minutes to download the almanac. Apparently it only needs to 'see' 1 satellite to do this. I fiddled around with mine for several hours before it managed to lock three satellites, (picked a bad time of day I guess, haven't had that much trouble since) yet it reported a full almanac after about 15 minutes. Regards, Guy
