This gadget and on the camera only does the first (a short burst), and postpones the other 2 for the moment we are getting the photos into the computer.<br />Let me give you a personal experience on my PDA: it takes me over a minute to get a fix, and only 30 sec. when I previously have synced the GPS positioning.<br />Thanks for your comment, hope I could helpMário Romanohttps://www.blogger.com/profile/17249260393075829950noreply@blogger.comtag:blogger.com,1999:blog-35686921.post-45275028760106072222010-01-20T17:18:40.015+00:002010-01-20T17:18:40.015+00:00I don't understand at all. What's describ...I don't understand at all. What's described here is not much different from the way a hand held GPS unit works. There's a bit that's not very well explained; it sounds as if the unit simply stores the last known point and uses that? Or perhaps one leaves it on always ( like a hand-held GPS ) and when you upload the photos the software simply matches your track log against the time stamp in the pictures? The article implies both.<br /><br />In any case, a traditional GPS will clip to your belt or back pack, record a track log which can be matched by time stamp, and will last a day or two on a pair of AA batteries. When these are rechargeable, and the unit is put into power save mode, a week-long camping trip in the back country is easy to pull off. With the unit on anyway to record your personal map, there is no delay in acquiring a fix; it seems like both mentions of this are straw men.Travellerhttps://www.blogger.com/profile/14332405883455355515noreply@blogger.com
