Portable GPS

Old Rookie - That is really cool that you can use your iPhone as a GPS. This is super tempting to me because I am a sucker for simplicity.

How certain are you of the accuracy on the iPhone. I've got the 4G and whenever I've used it for GPS location on Google or another application like say, a jogging app, the phone can't really do better than 20-40ft of my position. This is enough accuracy for me to justify not buying a handheld, but I'm curious how well it has done for you?

Any examples or stories would be great.

I have a blackberry so I can use that Ap. I still like my Garmin though.

I think the accuracy is very good. I used it to walk my dog and came across a skunk. The track shows how I walked to the other side of the street. There have been times that it wasn't accurate, but I think I didn't give it enough time to acquire more satelittes before moving. Otherwise I'm very pleased with it. I have a Garmin I've used and I think the iPhone is just as accurate. I wouldn't be surprised if Apple used a Garmin chip in their phone. The phone does seem to loose satelittes if I keep it too close to my body and block its view - so when I'm OTW, I need to be aware of its placement.

I got a Lowrance Finder H2Oc with Nautic Path chip & tell you the truth, I'm real happy with it; for so many years I depend more on it than my FF X67c
