The Watershooter T402 is an interactive toy which is actuated by cranking the handles. As the wheels are turned the unit sends a pulse of water from the nozzle. The watershooter contains its own pump and does not require a piped-in waterfeed. It can be aimed side to side and up and down. Waterdepth requirements are 8 inches ( 20 cm) to 24 inches ( 60 cm). The unit is excellent for retrofit or newpool installations by simply bolting to the pool slab. No elaborate footings or embedded anchors are required.
