Back by popular demand: The Classic Aqua Jump Water Trampoline for the commercial camp and resort market. RAVE’s Classic Aqua Jump 25’ has a steel bar frame around the perimeter of the tube that secures the springs and the jump mat (verses the Eclipse which has the springs connected between the tube and the jump mat). Because of its size, the metal bar frame plays a necessary role to hold the structural integrity for maximum bouncing. Heavy duty steel springs provide recoil for optimum jumping action. The largest Classic Aqua Jump, the 25’ has a monster 25-foot diameter designed for plenty of room for four adults or eight children.
