Sokkia ProLink Version 1.15 is a legacy hero. It is slow, it is picky about COM ports, and its UI looks like Windows XP. But it works. For transferring your last 5,000 survey points from an old Sokkia SD card to a CSV file, or for resurrecting a dead battery indicator via a firmware reflash, this tool is irreplaceable.
Pro Tip: Once you successfully connect, immediately use the "Backup Instrument Parameters" feature and save that .PAR file to three different locations. If your instrument's motherboard battery dies, that file is the only way to recalibrate without sending it to a service center.

Do not use ProLink v1.15 to update firmware if your instrument was manufactured after 2019. Later units (e.g., iX series) require Sokkia’s MAGNET Field Tools (version 2.0+). Flashing modern firmware with v1.15 can brick the mainboard.
Always confirm your instrument’s current ROM version before initiating an update. Disclaimer: Sokkia and ProLink are trademarks of Sokkia Co
