Yes, you can use your existing SteamVR base stations with the Bigscreen Beyond 2 headset. The Bigscreen Beyond 2 supports both SteamVR 1.0 and 2.0 base stations, which are part of the SteamVR tracking system[1]. This compatibility allows you to integrate your existing base stations into your setup, provided they are either version 1.0 or 2.0.
For optimal performance, it is recommended to use two base stations, especially if you plan on moving around or using motion controllers like the Valve Index controllers[4][7]. However, if you are using the headset for seated applications or minimal movement, a single base station can suffice, as long as there is no occlusion between the base station and the headset[3][4].
Keep in mind that the Bigscreen Beyond 2 does not include base stations, so you will need to have them separately or purchase them if you don't already own them[1][7]. The headset itself is designed to be lightweight and features improved optics, including a wider field of view and adjustable IPD, making it a versatile option for both gaming and non-gaming applications[1][5].
