If you are looking for more information about the GTA online sonar station, you have already considered it as an upgrade option when designing the submarine headquarters, or you have installed it and now want to know how it actually works. The description on the Warstock Cache and Carry website promises you can “use it to search for hidden treasures,” but it’s not obvious how you do this.
If you want to free yourself from the Cayo Perico Heist settings in GTA Online, then maybe finding hidden treasures under the sea is exactly what you are looking for, but with the vast ocean surrounding the GTA Online world, fruitless search if you don’t have the right tools. We have learned the inside story of how to use the GTA online sonar station, so you can collect some reputation points and cash from the sunken treasure.
How to install the GTA Online Sonar Station in your submarine
When you first purchase Kosatka from Warstock Cache and Carry, you can choose to install the GTA online sonar site for $1,200,000 in GTA game currency. If you decide at the time that you don’t need it or can’t afford it, don’t worry-you can always visit the Warstock Cache and Carry website and select the Kosatka renovate option to add a GTA online sonar station to your underwater HQ later.
How to use the GTA Online Sonar Station to find hidden treasure caches
After entering your Kosatka, you can operate the GTA online sonar station by approaching the helm controls (joystick and screens), sitting down and following the drive prompt. After entering the external view, a message will appear to toggle sonar. When you press it, the scan will be overlaid on your mini map, showing the location of the hidden cache. You can also open the main map and set the waypoint as a hidden cache when it appears for easy tracking.
Although you can drive the Kosatka to a hidden Cache place, you cannot actually retrieve it from the bottom of the sea while still inside the submarine. The easiest way to reach them is to install a Kraken Avisa minisub or Pegassi Toreador amphibious car installed within your moon pool, then start the vehicle and dive into the ocean floor to collect hidden Cache by driving towards it. There are 10 hidden caches for collection every day, and each provides an appropriate amount of RP and cash for retrieval.
