[pct-l] Pct-L Digest, Vol 52, Issue 5

[David Money Harris]

I have been using an iphone 3GS alongside my Garmin 60csx while mapping 
trails.  I've never had an issue with getting good GPS reception.  The 
quality of the tracks agrees well enough that both are more than 
suitable for the maps I make (note that I don't show topo lines, where 
an error of a few 10's of feet would cause the track to be way off when 
walking along a cliff).

I use iHikeGPS, which works well.  However, the battery life with the 
GPS constantly recording is only ~6 hours, making the iphone an 
impractical replacement for a hand-held GPS when mapping long trails.

Also, you have to download your topo maps to iHikeGPS in advance if 
you'll be outside cell phone coverage.
