When the SpyraOne appeared on Kickstarter in 2018, it set a new standard for water guns with "bullets" of fluid and a digital readout of how many shots remained. The SpyraTwo builds upon the same basic design. It can hold 22 semi-automatic blasts of water per fill, with a range of 30 feet. A three-second hold of the trigger releases a 46-foot blast, and it will automatically refill in just 12 seconds when dipped into a water source. The rechargeable battery lasts for 90 refills or a total of 2,000 blasts.
