Magic Trig is a puzzle cache. It has 4 satellite caches that contain only the distance to the actual cache. You have to find the satellites and then compute the location of the final cache.
That meant I hand entered the waypoints into the mapping program I use, MacGPS Pro. To my surprise in the field, the waypoints in the GPSr weren’t correct. Perhaps this is why I found only 1 satellite (apparently one other satellite is out of commission because of new construction).
Turns out the map coordinate systems of the Livermore map I am using the MacGPS is different from what the GPSr uses, so there is a coordinate translation that occurs when the waypoints are downloaded to the GPSr. I’ve corrected the waypoints in the GPSr and will try again.
