The Spyra Two is a battery-powered water gun that can fire a single shot of water up to 50 feet. To fill it up you place the end in water and pull the trigger forward. It has a tactical display that shows you how much water you have left and when it reaches zero it’s time to refill. When you pull the trigger it fires a single shot but if you hold it down and release it after 4 seconds it fires a longer more powerful one.
