Bionik 503 Putter

The Bionik 503 is the most popular of the 500 series. Why is that? Likely because it is a mallet style, which adds MOI, which leads to more forgiveness on an less than perfect stroke. Another reason is the generous alignment mark that makes it easy as pie to line up your putt. Combine that with the sharp black nickel finish, and you have one heck of a putter for the money!
