The SCUF Seal of Approval is found in different locations based on the controller type and is a unique number. The location of the Seal of Approval and the start of the unique number for each controller type is as follows:
SCUF Instinct = Found inside the battery compartment (you will need to remove the battery hatch) on the back of your controller.
SCUF Reflex = Found under the front trim (which you will need to remove. See how HERE.), on the right side of your controller.
SCUF Impact = Found on the back of your controller (starts with IMP).
SCUF Infinity 4PS Pro = Found on the back of your controller (starts with INF)
Older models:
SCUF Vantage = Found on the back of your controller (starts with A or B)
SCUF Infinity1 = Found under the paddle hatch on the back of your controller (starts with INX)
SCUF Elite = Found under the paddle hatch on the back of your controller (starts with ELT)
SCUF Prestige = Found under the faceplate on the left side of your controller (starts with XP)
The SCUF Seal of Approval proves that your controller is tournament-legal and contains no modifications which would otherwise disqualify it for use in competition. It also validates your warranty and shows the controller has not been opened or tampered with.
