The Seestar S50 uses a push-assist mechanism when closing the arms, which typically does not apply excessive force. If an obstruction (the Dew Shield on the market) prevents full closure, the system detects the resistance and stops applying force instead of forcing the arms closed. This should not damage the device.
Since your device has been successfully recalibrated and returned to normal operation, there is no immediate concern. However, if this occurs frequently, consider adjusting or modifying the Dew Shield to ensure smooth operation. We understand that many users rely on aftermarket accessories, and we appreciate your feedback on this issue.
