Difficulty (Search=>Filter=>General)
Use these fields to select caches based on the difficulty rating of the cache. By default, all caches are selected (less than or equal to a difficulty of 5.0). Use the first drop-down menu to select other difficulty options. The difficulty rating drop-down menu allows you to choose any of the standard difficulty ratings between 1.0 and 5.0. GSAK displays a second difficulty rating drop-down menu if you choose "Between (inclusive)" on the first drop-down menu.
