Use the Sky-Watcher SynScan GPS Module to obtain accurate date, time, and location data from the network of satellites, making setup and alignment of your mount faster and easier. Once obtained, the module sends the information to the SynScan hand controller; no user input is required. The module is compatible with all mounts using the SynScan hand controller. This is the module only; the mount and SynScan controller are required for proper use.
