Payday 3: Where to Find Flash Drive and Spectrophotometer
Payday 3 offers a lot of freedom to the players to complete the heists whether Stealthily or with a Bang but every heist has a certain set of main objectives that each playstyle must follow. One of the heists, Under the Surphaze, requires players to use a Spectrophotometer and a Flash Drive to find the real Uma Ladette painting. Without these tools, you will not be able to retrieve the real painting because the real Uma Ladette painting has security that you need to disable first.
Looking to know where to find Flash Drive and Spectrophotometer in Under the Surphaze, then you are at the right place. This guide will assist you in where to find Flash Drive and Spectrophotometer in Payday 3.
Where to Find Spectrophotometer
The Spectrophotometer is easy to locate and it can be found in the Server Room on the second floor of the Art Gallery. Make your way up to the Second floor and look for the Server Room. Picklock the Server Room door to enter inside and the Spectrophotometer will be inside the server room you can pick and place it anywhere you like.
Where to Find the Flash Drive
The Flash Drive is more hidden and a bit trickier to find because it is a lot smaller and it is not placed anywhere on the desk. To find the Flash Drive, you need to get inside the Manager’s Office. Find the Manager’s Office and picklock the door to get inside the Manager’s Office. Once inside, you need to open the hidden compartment located behind the desk in the Manager’s Office. Open the compartment to reveal the safe. Unlock the safe and you will get to loot the flash drive along with some money.

Now, that you have located both of the required tools, you can use them to find the real Uma Ladette painting to finish the heist.
