I see that it is not recommended that you fly the Mavic Pro over water. Yet some of the best video footage has been fllying over water. What is the problem for the MP when flying over water and is there some precaution that needs to be implemented before flying over water?

Similar comments are made about flying in low light but more and more videos are around showing great footage in the late evening. Is there a common problem here for both types of fllying. I realise that there would be extra risks for both types of flight due to the conditions not being optimal but is there something additional we need to be doing to prevent real problems developing flying with these conditions? Thanks

I fly over water 99% of the time and i have had zero issues, i got my Mavic 1 week after it's release and have countless flights !

If you are going to fly low, you should turn off Landing Protection, to avoid the quad to start an automatic landing sequence which you can't  abort...

There is no problem flying Mavic over water, in fact flying over water is one of the safest places to fly almos no obstacles much less radio interference.

My longest flight was 3.4 miles each way over the ocean at 10' of elevation

I am not familiar with 'Landing Protection' - I will have to go look for it in the settings. Is that what it is called in the menu? Thanks for the warning though I wasn't aware of it before when flying low.

Thanks hallmark007 - reassuring.

Thanks good to know.

I've flown dozens of time over water without any issues. Typically fly in (S) Sport mode with turns of the sensors - both front and bottom and I've gone as low as 17 feet over water with no issues.

Me too, I have had many flights over water without problems. Until this happened https://forum.dji.com/forum.php?mod=viewthread&tid=114336&pid=974787&page=1&extra=&mobile=2#pid974787
It's still unresolved what the reason was at the end. But be careful and keep in mind that if your baby goes down, it will go for a dive. Not exactly what the mavic is designed for...

I was watching a video yesterday on Youtube and the bottom sensors ARE working in sports mode - this guy was able to prove it a number of times because it was a surprise to him too - if I can find the video link I'll put it up but not all the sensors are off in sports mode (apparently). I'm new to the Mavic Pro so I don't want to sound like I'm the expert but the video was interesting.

Would you re-check and post that link right on here?

When I turn on (S)port mode, the sensors icon is lit in red. This means inactive. I've even tested having the Mavic head straight into my direction and it doesn't stop nor any alerts which indicates inactivity.

For reference see below.   

Straight from MP Manual:

S-mode (Sport) - The aircraft is using GPS for positioning. As Forward and Downward Vision Systems are disabled, the aircraft will not be able to sense and avoid obstacles when in Sport Mode. Ground Station and the Intelligent Flight functions are also not available in Sport Mode.
Note: Aircraft responses are optimized for agility and speed making it more responsive to stick movements.
  The Forward Vision System is disabled in S-mode (Sport), which means the aircraft will not be able to automatically avoid obstacles on its route.
The aircraft’s maximum speed and braking distance are signi cantly increased in S-mode (Sport). A minimum braking distance of 30 meters is required in windless conditions. Descending speed is signi cantly increased in S-mode (Sport).
The aircraft’s responsiveness is signicantly increased in S-mode (Sport), which means a small stick movement on the remote controller will translate into a large travel distance of the aircraft. Be vigilant and maintain adequate maneuvering space during  flight.

Hi Sportbike-Pilot, here is the link  

Go to option 2 (Sports Mode) at about 3.07 along the video time line and watch carefully. Let me know what you think?

Cheers

I've seen that video before and found that strange b/c it toggled between the two modes. Looks like it remained off then switched on. When I tested mine, it did not avoid obstacles.

Not clear to me what you’re saying but the video clearly shows bottom sensors are active in ‘Sports ‘ mode do you agree?

It's only the bottom senors that are active in sport mode. test it yourself!

I think I'll do a test run.

Yeah based on that video it's definitely active in the hovering position. guess the manual is obsolete.

For Moderators:

Is the manual inaccurate with the printed info or is the copter's downward sensors active in a hovering position?

If the Landing Protection is disabled, the result is the same.

Crazy eh - when the manual says one thing and it doesn't match? Bit like watching a dubbed Chinese/Japanese movie. Love the emoji with the spinning eyes I can relate to that.

Wondering if anyone knows if the sensors are actually disabled ?? or the manual has misprint? or a fluke?

Agree, just bizarre.

It only mentions that the visual systems will be disabled, no mention is made of the ultrasonic sensors used to maintain vertical position being inoperative.

"ultrasonic sensors used to maintain vertical position being inoperative."


Interesting. I always thought the GPS kept the copter lock in place when it hovered in sport mode but sensors were disabled. Guess I was wrong.
