Some of the visitors to Liverpool over recent months. Was a bit nervous about flying over water at first but now I have a float set fitted to my Mavic, I feel a bit bolder. Makes you more aware of the battery state as well… 
Queen Victoria
Prince Of Wales. Still very new and very shiny

What’s your float set ??
Thanks 
You’ll need more than a float set if you ditch it near the POW.
Just curious, I got over my water fear in Gili Meno when it went out of range but Litchi mission bought it back safe. 
One of these-cheap, light and effective 
Splash one Mavic!!!.. 
A review of those floats that I saw said that as long as all you want them for is to stop the drone sinking … then fine. But keeping it dry? Unlikely.
When it’s floating on the water, it’s very top-heavy, and it will only handle pond-like ripples. Anything more, and it will flip inverted.
Also - since the chances are these will only be needed in the case of an auto-land, you probably have already lost control … and the auto-land may not slow down over water as it nears the surface, since the visual system really needs some detail - so you are reliant on the ultrasonic sensors, and the reflection from water is a bit iffy.
As a result, a standard descent speed auto-“landing”, will (a) probably dunk the drone, and (b) cause it to flip … even on a smooth surface.
Agreed, I’m aware that they wouldn’t prevent a total loss, and they obviously do not make any guarantees to that effect, but something is better than nothing. Without them-definite loss. With them-a slight chance of retrieval, albeit a bit wet and maybe needing repair.
I’ve tried them on pond-like ripples near me and they were OK. But the Mersey? Probably not!
cheers
Best thing is to go at extreme low tide.
And be thankful for small Merseys …
Absolutely, where I stand is not very far from the shipping when the tide is low, decreases the odds of loss!
Small Merseys…I see what you did there
I’m thinking the floats could be the difference between getting the drone back or not. If you are covered by DJI Care you will need to return the drone to them … if you don’t have it then too bad.
From years of flying over water with zero issues I’d be worried that the floats contributed to an accident.
Wouldn’t fancy using them in anything more than a light breeze.
Under appreciated this response
