The included R03 Pro waterproof smart controller features a bright 700-nit touchscreen, allowing clear visibility even in direct sunlight and precise control even with wet hands. Combined with intelligent flight modes, automatic return functions, and stable payload flight control, the SplashDrone 4+ offers unmatched versatility for fishing, filming, search & rescue operations, and marine inspections.

Whether launching from the shore or a boat, the SplashDrone 4+ delivers a powerful, reliable, and safe aerial platform designed specifically for water environments and serious anglers.
