Explain :
The water volleyball game system is the essential volleyball game for municipal pools, community centers, health clubs, luxury resorts, cruise ships and other commercial and residential locations that demand continuous action, non-stop performance and no-nonsense safety features. Dual, high capacity, rugged plastic bases each hold up to 50 gallons of water (or sand!) to create stable platforms that virtually anchor to the deck. Neither ferocious spikes nor lunging blocks into the net can move these bases.
Make pool parties memorable events. Everyone gets in the pool to play volleyball with the Chinee Water Volley. The water volleyball features dual, rugged, rotomolded polyethylene bases that when filled with 17 gallons of water (or sand), virtually anchor to the decking. The anti-tumble design creates a stable platform that keeps the bases out of the water, even in the face of a fearsome spike. The Water Volley system is brought to you by Leisure Living.
