Could you please show DualHorizontal Hinge on a picture. I really have
difficulty trying to imagine this hinge.

In Dual Horizontal Hinging, the Left Arm is the second
("dual") hinge. It is "attached" to the primary
Horizontal Hinge (that controls the Clubface alignment) and serves as
an Angled Hinge that lowers the Club vertically onto the Inclined Plane (that
controls the Clubshaft alignment).

The Golfer using Horizontal Hinge Action (a Closing Only Motion of the
Clubface) is almost always also attempting to maintain the Clubshaft on an
Inclined Plane. Therefore, for all practical purposes, the two terms -- Horizontal
and Dual Horizontal -- are interchangeable.


The only exception would be with Putting and Chipping, where at the Player's
option, Horizontal Hinging can be produced while maintaining the
Clubhead directly on the Target Line, i.e., in a Vertical Plane of Motion.
Because such a procedure eliminates the Inclined Plane, there is no need for
a second Hinge to control an Angled Plane of Motion. Hence, Horizontal (Only)
Hinging is the designated Variation, not Dual Horizontal Hinging.
