Borderlands 4 (BL4): ECHO Log Locations & Interactive Tracking Guide

In Borderlands 4, ECHO Logs are the primary source for the game’s deep lore, offering recorded messages from former inhabitants and key characters across the planet Kairos.


While they do not grant direct combat buffs like SDU tokens, finding them is essential for 100% regional completion. In total, there are 156 ECHO Logs scattered across the world—from the peaks of the Terminus Range to the swamps of the Fadefields.


Collecting every single log is the only way to complete the "Kairos Speaks" challenge, which rewards you with the exclusive DECO-4 Frame cosmetic for your ECHO-4 drone companion, along with significant XP and Eridium.


While you are exploring to find these audio diaries, you should also maximize your route by completing other regional objectives. Some logs are hidden inside areas that only open during specific side missions (e.g., "The Kairos Job" or "Unpaid Tab"). If a map marker seems unreachable, check your quest log first.


Because many logs are tucked away on rooftops or inside locked bunkers, we recommend using our BL4 interactive maps to track which specific logs you are missing. All of them are listed below, with links leading to their locations on our maps.
