Signal To Noise is a Crew Challenge in the fourth DLC of Borderlands 3.
Each main map should have this crew challenge, including Sapphire’s Run.
Here are all of the Signal To Noise locations in Sapphire’s Run in Borderlands 3.
First probe location
The first location is nearer to the entrance of Sapphire’s Run. The location is shown in the map below.
You should see the device on a floating boulder. To get up there, place Maya’s book.
Once you have access to it, start the device and shoot at all the areas the laser is pointing towards.
Second probe location
The next probe location is shown in the map below. It’s at the beginning of the special map opened by the Locomobius to trap you inside.
To get to the device, place Maya’s book.
Like before, activate the device and shoot at all of the laser ends before the time runs out.
However, this time, you will need to jump on the other platforms to be able to shoot at one of the lasers.
Third probe location
The third location for Signal To Noise is on the map before you fight the final boss. Its exact location is shown below.
Like before, place Maya’s book to form a path.
Like the second probe, you will need to jump on the further platforms to be able to hit all of the lasers.
