This is not the full C3 VacuMount Kit nor System Kit. The Kit and System Kit are sold separately.
This is an accessory to be used in conjunction with either the VacuMount Kit or System Kit.
The "Basic" Tilt Plate is a lightweight, universal tilt plate for various camera settings (tilt, turn). The C3 VacuMount is designed in such a way that it can hold the camera, gimbal and lights directly, or mounted with a wedge/tilt plate, ball mounts, etc.
