The simplest way how to get geocaches into the app. For a quick overview, check the video tutorial:

Detailed instructions:

• go to the main menu > All features > Geocaching > Geocaching tools > Search for geocaches (the first search triggers logging in to the Geocaching.com website and permission to share its data with Locus Map):
  
• 1) select the location around which to search the geocaches - the screen center is the default. If you want another, tap the location selector button.
• 2) set the number of geocaches from 10 to 500

• go to the main menu > All features > Geocaching > Geocaching tools > My lists & PQ

Create Lists of geocaches at Geocaching.com to organize your geocaching outings and goals.

This way you can download geocaches from the lists into the app:

…also known as PQ or just query, is a GPX file with geocaches that was rendered at Geocaching.com according to instructions from the user. For example, it is possible to define all geocaches with difficulty grade 3 within a circle of a certain radius around given GPS coordinates.

This way you can download geocaches from the Pocket Query into the app:

Another option that adds more geocache downloading functions into Locus Map, created by a partner developer.

• Download and install it from Google Play Store
• Start Geocaching4Locus - Menu > All features > Geocaching > Geocaching4Locus
  
• Geocaching4Locus menu appears, select Settings > Account > Sign in
• Enter your Geocaching.com username and password and confirm
• Authorize Geocaching4Locus by tapping Allow access
• Make sure that Locus settings > Miscellaneous > Connect with add-ons is turned ON:
  

After installation and setup the following options appear across Locus Map:

The option to find the nearest geocaches around a selected location can be found in several places:

• Menu > All features > Geocaching > Nearest caches
  
  Set coords or tap GPS to get your location
• Tap any point (user point or LoPoint) on map > detail screen > bottom panel > add-on button > nearest caches
  
  This searches for geocaches nearby the point.
• Long-tap any place on map > address detail screen > bottom panel > add-on button > nearest caches - searches for geocaches around the the selected place on the map (the on-screen address search must be enabled):
  
• in Geocaching4Locus menu:
  

What to do next:

• set number of geocaches to download and filter of caches (optional)
  
• Tap the download button
• Select a folder for your caches, check Show on the map after import and tap Import. You may need to empty the import folder before downloading caches to save place in your device memory so check the option. Locus Map Premium users may also let Locus update the elevation of the imported caches.
• Geocaches appear on the map.

With this feature, the geocaches appear above the map in real-time without import - you have to be online.

Each geocache has its own unique GC code. Use this feature to import a particular geocache by its GC code.

GSAK is a geocache management program where you can edit the final waypoints, add notes or other auxiliary points, or import/export geocaches.

This add-on provides a link between GSAK where the geocaches are stored and Locus Map. With this add-on, you can view all geocaches, you have stored in GSAK, display their listing, and more. And all this offline without an internet connection.

The add-on allows you to import caches from db3 files from GeoGet for further work in the Locus Map application. If you use one file, the application will start loading the cache immediately. In the case of multiple files in a folder, the add-on will first offer the option of which file to import.

C:geo is an open source, full-featured, always ready-to-go unofficial client for geocaching.com and offers basic support for other geocaching platforms (such as Opencaching).
