Comes with: 2 Trackers + 2 Straps Note: These fullbody tracking VR trackers are designed to work in conjunction with the OZI Tracker system. In the case of this announcement, we are offering a set of 2 trackers, both from the P3 model. It is important to note that these P3 trackers are specifically intended for customers who have previously purchased OZI Tracker. If you've already purchased a set of 5 OZI trackers, for example, and want to expand the functionality to include foot tracking, this extension ad is perfect for you. Each set of 5 OZI trackers includes 1 OZI-5, 2 OZI-3 and 2 OZI-2. The OZI-2 trackers have a specific P3 input for connection with the OZI-1. Please note that these extension trackers, advertised here, are OZI-1 only. For them to work correctly, it is essential that you already own the OZI Tracker tracking kit. They are an addition designed to complement existing OZI sets and enhance your full body tracking experience.
