3.4.2 Handling the Unwinder String
In the unwinder body, the unwinder string runs under a round plastic clip (number 4 in
Figure 5 (page 23)) on the bottom plate. This keeps the string attached to the unwinder, and
the radiosonde attached to the balloon.
1. To prevent the string from getting tangled in the clip during the sounding, make sure
the round plastic clip is level with the unwinder bottom plate.
