Hidden Caches

Hidden Caches are a recurring collectible in Grand Theft Auto Online, added as part of The Cayo Perico Heist update released on December 15, 2020.

Description
If a player has purchased the optional sonar upgrade for their Kosatka submarine, then whenever they are inside their own sonar-equipped vehicle such as the Kosatka, Avisa or Toreador, they will be shown a prompt informing them that turning on the sonar will reveal hidden caches.

There are ten hidden caches scattered throughout the state of San Andreas, all located underwater. If the sonar is activated, it will reveal all caches, regardless of distance from the player. The caches also emit a beeping sound, which helps with locating them. They can be collected with or without a vehicle, and each will give the player $7,500 and 500 RP upon collection. Players without a sonar-equipped vehicle can still collect them, however they will have no way of knowing where to look for their caches. Sonar can not be borrowed from other players. Passengers in a sonar-equipped vehicle do not see the sonar, however if the game has coincidentally spawned the same set of 10 caches as the owner, non-sonar-owning passengers can passively collect their caches simultaneously.

These collectibles are available daily, so a new set of ten caches appears every day, regardless of how many were collected the previous day. There is a large selection of possible locations, from which ten are randomly chosen. Players can track their progress in the Interaction Menu, under Inventory > Daily Collectibles > Hidden Caches. Partial completion a previous day carries over to the new day, even though the locations are changed.

Each character on an account has their own daily counter, allowing the player to collect the cache rewards twice a day if they are using both character slots.
