Does anyone use the DistanceMap app for ranging? Seems to be pretty accurate if you can locate where your target is on the map.

Is there no option for standing next to your target and pinning it, then doing the same from your shooting location?

Re: DistanceMap iPhone App
I doubt if it is possible through direct GPS measuring better than with good LRF.
What we can usually get is 5m accuracy and about 1.0 HDOP (horizontal dilution of precision). It means real position is +/- 5m.
Best solution I got is on android - LocusPro + GPSAveraging. GPSAveraging scans position multiple times, then compute average gps coordinates. LocusPro imports GPSAveraging data and it is possible to see distance between points. In general it works equal to LRF. Sometimes error is crazy. It depends on atmosphere/sattelites.. maybe something more. Never checked how this works under downhill/uphill.

That's actually a really good point. You can always move the pin slightly if it appears to be off. Right now, I'm lying in bed but GPS shows me about 3' behind me in the side yard.

I used Google Earth overseas to make some range cards for some FFP's in sector. It was great to have a ballpark range going in, then fine tuning it with a PLRF.
