Features:
-
Bold, symmetrical,
sleek and powerful.
-
Inspired by the
enormous, but graceful manta ray, the clubhead takes on a
"square-like" shape. Why? All in an effort to move more weight
further from the center of gravity (or out toward the outermost
perimeter of the head) creating a slightly high moment of inertia
over a traditional shaped driver. This makes the Mantara more
resistant to twisting at impact resulting in straighter, more accurate shots off the tee.
-
Featuring the same
radical square design as the original Mantara, the XL version is
broader from front-to-back (8mm), but slightly shallower (4mm) to
retain the 460cc limit. This moves the center of gravity not only
further back, but lower as well. This helps to maximize the moment
of inertia, resulting in less twisting on off-center shots, making
it quite possibly our most forgiving driver to date.
-
The easy to align
aerodynamic profile is constructed from a 6-4 titanium face and a
thin, lightweight titanium crown, skirt and soleplate.
-
Conforms with USGA
Rules.
-
The large 460cc head
with multi-sculpted crown and sole will catch the eyes of your
playing partner's and boost your confidence at address.

Shafts:
Before you select the shaft to go with the
Mantara XL Square clubhead
please read the following write up. It will help you select the right shaft.
-
The shaft is the engine of your driver. It
does not matter how expensive a clubhead you have - if the shaft is not
right for your swing, the results will not be satisfactory.
-
The faster your clubhead speed at impact, the greater the distance. To maximize club head speed and distance, you should play the lightest shaft
you can without losing control. The key here is 'without losing control'. A 300
yard drive is of no use if it is out of bounds.
-
Ball flight is affected by several factors like loft, ball position, angle of
attack and wrist position at time of impact. A tip flexible shaft can help
increase launch angle while a stronger tip can help produce a penetrating ball
flight.
-
Lighter weight shafts in general are more active than heavier shafts. All things
being equal a lighter shaft will give you longer distance on center hits. It
will be off more on off-center hits. Take into consideration how stable your
swing is. The more stable and accurate your
swing and swing path, the lighter the shaft you should consider. The
more load you apply to the shaft at the last quarter of the swing, the lower the
torque and heavier the shaft needs to be.
-
Newton's Second Law:
Newton's second law is one of the laws of
physics that applies to golf.
F = m a
I = m r2
T = (m r2 ) A
F=force, m=mass, A=rotational acceleration, a=linear acceleration, r=radius,
I=inertia, T=torque
-
Moment of Inertia (MOI):
MOI is the term applied to a clubhead's resistance to twisting when the ball
is struck. It is more important on off center hits. If you hit the ball on
the toe of the clubhead, a clubhead with a higher MOI will twist less as a
result of the miss hit, creating a better chance that the ball will still go
straight or at least not deviate too much from it's intended path.
-
Torque:
Torque is a shaft's resistance to twisting during a golf swing. A higher
torque rating means the shaft twists more and too much torque can lead to
the head turning.
-
The longer the shaft, the bigger the head or the heavier
the club head, the higher the moment of inertia. The higher the MOI, the higher the torsional load applied to the shaft. Therefore, if
you are using a big head or an extra long shaft and have a high swing speed, you need to
consider using a lower torque shaft to compensate for the extra load applied to
the shaft.
Here are the shaft options we have configured for you.

The swing speed to distance ratios
above are not related to this driver or shaft. These are averages, i.e., an
average person with this swing speed will hit the ball so far with an average
driver on center hits. We hope with this driver and the right shaft, you will do
better.
Note:
When making payment, in the comments/notes section of the order form, mention your
preferences for driver loft, shaft make/model and flex. Otherwise, the
default will be shipped which is the Acer Mantara XL driver, right hand 12 º loft with the Acer X Class
Orange
shaft in regular
flex.
Grip:
Karakal X-Tack Red/Black grip
The grip plays an important role
in maintaining a steady but firm hold on the club. The square head and preferred
shaft is of no use if your hands cannot maintain proper control of the club. The
X-Tack is more expensive than stock grips but we believe saving a few dollars on
the grip won't help you maintain consistency in your swing. The X-tack is manufactured with a
combination of polyurethane and fiber layers which makes the grip feel firm but
comfortable and provides shock absorption. The final polyurethane coating
insures a long lasting tacky feel even in wet conditions. The red and black
color goes very well with the rest of the club.

Note:
In case we have confused you, you
will get a complete driver that includes the Mantara XL Square head, a shaft of your choice and
the Karakal X-Tack grip, fully assembled. All the above write up is to give
you a better understanding of what you are getting. You are not ordering parts
but a complete driver assembled with the shaft of your choice.
