Keep in mind just a little note!
The Wave is an accessorie which can be used on any device to stabilize the horizon not only on the Steadicam. It is a very helpfull device also for Handheld, Shouldermount, Easyrig, Twister, Cars, Boats, Remote Heads etc.
Operators love it and we do not know even one person who sold the Wave cause of bad function etc.
The Steadicam Volt is a more than great device and a must but it is fixed on your Steadicam.
