The HOBO Waterproof Shuttle performs several major functions:
• Reads out all logger information (serial number, deployment number, data, etc.) from
loggers in the field for transfer to host computer, and stores each logger's data in a
"bank"
• Nonvolatile memory preserves data, even if batteries are depleted
• Relaunches the logger, resetting the logger's time to the shuttle's time and
synchronizing the logging interval on relaunch
• Can be used as an optic-to-USB base station
Although the HOBO Waterproof Shuttle is easy to use, Onset strongly recommends that you
spend a few minutes reading this manual and trying out the procedures described here before
taking the shuttle into the field.
