Well, imagine you are having a water fight and need a water source to keep your SpyraTwo tank filled up. What do you take? A heavy and unsteady tin bucket? This may work at home but if you are going on a water fght adventure into the wild you don't need something as un-handy and un-cool as a tin bucket. Try fitting that into your backpack! What do you say - you just take nothing except your SpyraTwo and use whatever lake or river you come accross? Well, ok but that's not gonna work if you are planning on playing in teams. Or do you want to be in the team that's blocked off their water source because your opponents are smart enough to just hang around there and wait for you? No, of course not. So, seems like you need some handy, lightweight and portable water bassin that's not made out of tin and tips over whenever somebody breezes by too close. How does a sturdy but foldable, lightweight but stable, flexible but unbreakable water base sound? Still not convinced? Then how about this: the SpyraBase comes in the colors of your SpyraTwo making it easy to distinguish team red from team blue, meaning it is an essential part of any water fighter's standard equipment.
