The vast majority of my flying to date has been around beaches and over water. Yes I do have DJI Care in case it ends up in the drink, and yes I always attach a Getterback with its 100 ft of Kevlar line to rescue the drone so I can send it back to DJI for replacement.
That said, I am now wondering the merits of purchasing this kit as a further level of protection. Not necessarily to land it on the sea (apparently has to be really calm to do so), but more to make it easier to retrieve in case of a downing.
Has anyone else had experience with this rig and can advise whether it would be worth the expense or just end up with my other 'bought it but useless' pieces of junk?
