Do I need to buy a FlexTILT Head for the PocketSKATER 2?

There is no need, Pocket SKATER 2 has already a built-in FlexTILT Head mechanism on it!

The built-in FlexTILT Head provides simple angle, height, and rotation adjustments to further enhance your shots and it also allows you to shift the center of gravity to achieve perfect stability in different setups.
