Flying over water yesterday afternoon. 75' or so above surface, Remote and Battery fully charged.
Heard two warning like beeps.... because I had my eyes on the Drone I didn't notice what the Remote
was saying if it was indicating anything at all. My heart skipped a few beats as I flew it in.
Any idea what the two warning type beeps could hace been?
Thanks!

Check your flight log

Hi, thanks for the inquiry, please do no fly closely above reflective surfaces such as water or snow as these terrains may affect the performance of the vision positioning system.

How close is too close? He said 75 feet... is that too close? 100 feet? 150 feet?
"do not fly closely" is very subjective

Hi, thanks for the interest. We will check this scenario to the right department for further clarification. Thank you.

75 feet is plenty of height above the water. I would just replay your flight log and see what pops up. Could have been a Wind warning or maybe max rotor speed. But no one knows until you review your log.
