Keep in mind I'm NOT... a "drone expert" just a guy that flies over water ALL THE TIME.
After some pretty extensive testing... what we learned is that you have to SEE IN YOUR MIND what the bottom sensors see.
The drone DOES... get confused over water in certain situations, but this usually happens when...
1- You are flying very close to moving water like a stream. (3-8 feet)
2- When you are close to ONLY water and you have prop wash on the water surface.
Did my best to explain it here.
