Overview: The waterproof barometric membrane is SwellPro's featured technology. It allows air to pass through the internal chamber of the aircraft to ensure the barometer's proper functioning yet keeps the water from getting in to ensure the SplashDrone 4's all waterproof design. Important: Always check the waterproof barometric membrane to ensure no damage being observed before flying.• Rinse the waterproof barometric membrane thoroughly with freshwater every time after flying.• If you constantly fly your drone in the saltwater environment (sea), it is recommended to change the waterproof barometric membrane once every 2 months, since the salt particles can clog the tiny holes on the membrane. In the Box: Waterproof Barometric Membrane x 1 set ( 5pcs） Compatibility: SplashDrone 4
