Geocaching Swiss Army Knife, also called GSAK for short, is a geocaching utility that helps you import and export database queries for geocaches. For example, you can run a query for geocaches in an area and import the results from a website to your computer. You can get the data in both .LOC and .GPX formats. Normally, with the .LOC file, you will only get the coordinates required to find a geocache. With GPX format, your GSAK can import all the additional information, such as hints, making it easier for you to determine your next trail.
If you thought the software was only for importing and exporting geocache data, you got it wrong. It is capable of making the game easy for you by offering you waypoints, helping you add notes, upload notes to the geocaching portals you are using, and more.
The software comes as a free trialware, valid for 21 days. On the 22nd day, you have to buy it if you wish to use it. If you don’t, the software starts presenting nag screens that increase in frequency with each subsequent use. The price is nominal at $20. The trialware has some features locked but once you purchase it, you can utilize the full capacity of the software. The default geocaching website (URL) that comes with GSAK is geocaching.com. You can easily change it to any other geocaching website in the full version.
