We take every drone and Submerge it in the water and than reverse engineer to develope the Wet Suit in order to sustain whatever went wrong ,     
 
The protection that the Wet Suit Provides the Phantom 4 has allowed us to push all the limits when it comes to Severe Weather Conditions/ or landing in the water. 
 
The Air 2 Wet Suit Provides the Drone with an Air Tight Seal on the Battery and the Power Button every time you fly. 
 
You may think that the prop covers that come with the Phantom 4 Wet Suits  are used for keeping the Rain out but that is not the case.     Those prop covers are critical to keeping out the Salt , Sand and Stones when on the beach.
 
The DJI motors all use Aluminum Brush-Less motors , these special motors are the exact same motors used in Submercibles designed to negotiate water .
 
The weak point on the Phantom 4 Pro was the Power Button, followed by the Battery when water gets into the Power Button or the Battery the Phantom 4 comes crashing down.   You only get 1 Warning when flying in the rain :   The Battery can no longer connect to the controler and down she goes.  its about 5 seconds  
 
 This is why the Focus of the Wet Suit was to provide an Air Tight Seal across the perimiter of the battery and the Power Button .
 
Once you have the Phantom 4 Geared up with the Wet Suit  , you have a completely different drone and when combined with the Phantom 4 Rescue jacket able to crash into the Water and cheat death which is very rewarding. 
 
Its an amazing combination , a perfect balance of Engineering to provide a light weight stream lined design for your Phantom. 
 
    If you get a minute check out the Phatom 4  Rescue Jacket , even if its just to see the Wet Suit in action,  its worth seeing just how well the Wet Suit protects the drone in the water and on the waves.
