Callaway Golf 2017 Men’s Great Big Bertha Epic Sub Zero Driver Product Review

Since their founding in 1938, Callaway Golf has always tried to lead the industry in innovation, and with the Callaway Golf 2017 Men’s Great Big Bertha Epic Sub Zero Driver that innovation is still noticeably present.

With cutting edge technology that changes how the head and face behave at impact, the new design allows for more speed across a much larger area of the face, which will increase your average distance.

The Sub Zeros ingenious combination of a titanium eco cage and a triaxial carbon crown and sole provide exemplary forgiveness in a high launch, low-spin design.

Offering two different head weights of 2 grams and 12 grams, respectively, this allows the user to adjust not just spin-rate but launch angle as well.

For lower spin, you can insert the 12-gram weight upfront, but for a higher launch, merely place the weight at the back.

The new streamlined head has the addition of the Callaways proprietary speed step. Designed with the assistance of aerospace experts, the speed step, allows you to gain additional speed and distance from the improved airflow.

An exceptionally designed driver that comes in four premium shafts, each one specifically designed to improve control, speed, and power.
