Take a look at the review and testing of the Steadicam Volt Smartphone and GoPro gimbal that takes a different approach for stabilization.
The Steadicam Volt funded by Tiffen is equipped with a 3-axis gyroscopic stabilizer, allowing you to get extended stable video footage in two modes; “Movie” and “Sport”. Once balanced the Steadicam Volt’s, motorized gimbal will transition to work manually even if the batteries have run out, unlike any other gyro-stabilized gimbal. Weighing only one pound, the Steadicam Volt provides increased mobility without jeopardizing stability.
The Volt holds smartphone sizes with or without case from 100 – 250g in weight and 58 to 85mm wide. Compatible smartphones include iPhone 7 & 7+, Samsung Galaxy S8 & S8+ and many more.
