The standard Helix was redesigned taking inspiration from the design of the Double Helix.
The Helix Pro has 19mm carbon fibre rods for the camera to sit on and benefits from the front ring support.
Resulting in a system which is more stable, easier to balance and allows the use of a wider range of lenses.
The Helix Pro has been used with the following cameras:
A7s i & ii
This Helix can stabilise camera configurations weighing around 10kg however compared to the Double Helix you are limited to the size and weight of your builds which for some will matter and for other users is not an issue.
