COrrected Coordinates
Ok, so you have solved the cache, now you need to go to the correct coordinates rather than the dummy ones.
In the "olden days" with my early GPSr I simply entered the coords I had worked out and marched off. Over the years I have become more sophisticated!
GSAK
The method I have used for some time now is to download pocket queries into GSAK. When I have worked out the answer to a puzzle cache, I store the answer and the workings in the user notes, and update the coordinates (right-hand mouse click, corrected coordinates). When I download these to my GPSr using the GarminExport macro I tick the include User Notes box. That gives me notes as a log entry and the coords stored for the cache are the correct ones rather than the dummies.
They have also introduced an option on geocaching.com to update the coords there (click on the pencil after the coords at the top). When you download the file into GSAK, it now shows the corrected coords, so if you are going the GSAK route you can choose where to store the corrected coords.
Smartphone - geocaching app
If you update the coords in geocaching.com and then go to c:geo on my Android 'phone using c:geo, it shows the corrected coords, and also the original position of the dummies. The same is true for the geocaching app, which I now use. It shows the new corrected coords and has a special symbol for the cache now, which shows in the app and also on the cache page on geocaching.com. In fact, you can update the coords on geocaching.com or in the geocaching app, and it syncs between the two. It is all explained here.
Results of some testing for cache owners
If you are the owner of puzzle or multi caches, then as part of setting up those caches you have to enter a final location waypoint on geocaching.com (which will of course be hidden to everyone else). When you download a pocket query (into GSAK for instance) the PQ does not contain the coords for final locations - they are blank - unless you have updated the coords using the pencil as described above. If, however, you download the gpx file from the cache page, then the final location is in there with the coords (right at the bottom of the file) and if you load this into GSAK, it will appear as a child waypoint (right-hand mouse click on the relevant cache in the list in GSAK). There is a macro for moving child waypoints to corrected coordinates.
geocaching.com
After I had written all that and come up with various ways of doing it, geocaching.com introduced the ability to edit the coords on the cache page as explained above. So you have a range of options to choose from nowadays. Just make sure when you have solved a cache, that you have the solved coords as the ones you are heading for rather than the original dummy ones! I personally still keep the details of how I solved the cache, and the corrected coordinates in GSAK, as people often ask me about a cache I have solved years ago, or I am going to collect a cache I solved years ago and I want to check that it hasn't been updated in the meantime.
My GSAK solution for use c:geo - don't use any more, as I use geocahing app instead
What I ended up doing was creating a filter in GSAK for all unfound caches with corrected coordinates and I exported that to my GPS. I copied that file to a folder called gpx (which I created) on the storage card on my phone. I then went into c:geo and in the stored caches screen pressed on the manage caches option and chose import gpx. Takes a while as it loads the caches and then static maps for each one, but at the end I have all my corrected coords on the phone.
For those of you with c:geo, here is a link to a useful doc on how to load PQs and how to load offline maps.
