Starting from July 1st 2019, all the KOLIDA GNSS receivers we delivered for China market will be installed with "Region Lock" program. This program will restrict and inhibit GNSS receivers from receiving satellite signals outside China.
None of the Chinese company online shops in Alibaba, ebay or any other E-commerce platform were authorized to sell KOLIDA GNSS Receivers or Total Stations to overseas customers. In order to avoid unnecessary financial losses, please buy instrument only from authorized KOLIDA distributors.
