The BUG-A-SALT 2.5 in classic (but reverse) yellow features an automatic safety (resets every time you shoot the gun) and is recommended for anyone with small children or pets in their household. The improved sighting on the 2.5 model will result in an even higher backyard bug safari takedown. In addition, Lorenzo Maggiore, inventor, has re-engineered the internal mechanism, allowing for greater reliability in the heat of battle, plus longer lasting fun. An easier, smoother spring on the cocking mechanism enhances ease of operation. The 2.5 model is excellent for eradicating flies without damaging hard to reach spots such as windows, screens, or blinds. Operating the BUG-A-SALT is very simple. Table salt is loaded into the hopper. You cock the gun by sliding the handle towards you. This will engage the pop-up sight (indicating the gun is ready to fire). Slide the handle all the way forward, release the safety - and you are ready to aim, pull the Trigger, & Fire. If you are not accustomed to shooting/throwing anything at a target, you will need to invest some time in practicing how to aim. Practice aiming by drawing a bullseye on a sheet of aluminum foil. Place the target three feet away from the tip of the BUG-A-SALT and aim for the center. Ordinary granulated table salt works best. Sea salt tends to be too moist and kosher salt is often too large to fit inside the barrel. The Bug-A-Salt Code of Conduct is as follows: 1. Do not point the BUG-A-SALT at anyone! 2.
