Look at the brightness on the orange fill of a Ping G10 golf club. On counterfeit models, the paint is too bright due to it being a different type of paint. Other features that indicate the club is a fake include the engraving for the words "Ping" and "G10" not being as crisp or defined as the original, or the number "9" located near the shaft designating the loft. The head covers for the fake clubs are also differently colored due to different materials being used.
Examine the finish on a Ping Rapture V2 iron. The finish on a counterfeit club has a more brushed look as opposed to the genuine club, which has a shiny finish. The cavity badge is also made of a much cheaper material, which shows in its appearance with differing contours. The shaft for the counterfeit edition is also a darker shade of green than the genuine article.
Check for corrosion on a Ping G10 iron. If there is any indication of rust in the cavity, then this would indicate a fake because a lower-quality finish was applied, which does not provide the same protection. Other indications of a counterfeit club include a smaller cavity badge and dot on the hosel of the club. If the club has a generic font designating the iron number, then it is most likely a fake, as Ping uses its own, more stylish font.
Note the serial number and distinguishing features of the club. Call Ping at (800) 4-PING-FIT (800-474-6434) and provide the details of the club and the manufacturer. Ping should be able to tell you if the club is a genuine Ping product.
Purchase new Ping clubs only from authorized Ping retailers to ensure you get a proper set of Ping clubs.
