Choosing the right PST tracker
PST Pico: Best for short-range tracking in compact environments like head-mounted displays (HMDs) or small devices.
PST Base: Ideal for mid-range tracking in simulation environments with precise accuracy.
PST Base HD: Enhanced version of the PST Base with improved resolution for more demanding simulations.
PST Iris: Suited for long-range tracking, such as in industrial or medical simulations.
PST Iris HD: The premium option, offering superior accuracy for high-definition, long-range tracking needs.
Each tracker is designed to meet specific tracking needs, from short to long-range applications, ensuring flexibility and precision across industries.
Note: The wider the tracker, the better it performs at larger distances, with the PST Pico being best suited for short-range, PST Base for mid-range, and PST Iris excelling at long-range application.
