A: While we have not applied for an official ruling regarding use of the GripFinder in matches sanctioned by the United
States Tennis Association (USTA) and the International Tennis Federation (ITF), we have read the official rules around
the racquet and “attached objects, protrusions or devices”, and we believe that it is acceptable for use in tournaments
and other sanctioned matches. Lots of other attachable racquet components and devices, such as lead tape, ribbed
over-grips, silicone butt-cap covering devices, etc. are used by players every day in official matches sanctioned by the USTA and ITF.
