Ping’s cradle lets a player attach his or her
iPhone4 or iPod Touch to a putter shaft.
in place and then enables golfers
to clip them onto their putter just
below the grip. Available in lead-
ing green-grass golf shops and
off-course retailers, it carries a
suggested retail price of $30 in the
States (and a comparable cost in
other parts of the world).
Next, there is the iPing putting
application, which utilizes motion-
sensing technology from the
mobile devices in those cradles to
analyze a golfer’s putting perfor-
mance based on three criteria:
putter face angle at impact, putter
stroke type (straight back, slight
arc or strong arc) and tempo
(in essence, a measuring of the
backswing relative to the forward
swing through impact).
