Leica Geosystems industrial grade media storage are built to withstand the demanding read/write cycles of Leica surveying instruments. Compared to conventional storage devices that read or write single data, industrial grade storage devises have a different functional principle. TPS or GNSS instruments create a database on the memory card and switch constantly between different open files. Standard memory cards are unable to manage this required multi-tasking function. This leads to problems in data communication and data loss. Leica storage media are designed to function with the highest reliability in extreme temperatures, handling shock, and high humidity.
