Heading off on a slight tangent here, does anyone know if wrong altitude readings affect the hunt?
Cache coordinates are 2 dimensional (lat. & long.), and if the GPSr uses the third dimension (altitude/elevation), it will set the waypoint elevation to the unit's current elevation at the time of inputting the waypoint coords.
if there is a difference of say 100 feet or more in elevation/altitude between the recording of the waypoint and the location of the cache, wouldn't this (shouldn't this?) give readings of something like "80 feet to go" even if you happen to be standing next to the cache???
I mean, wouldn't the GPSr figure that third dimension into the distance calculations...and inherently be wrong since no altitude is ever given for a cache?
