In order to safely and effectively play paintball, your gun must have a safe muzzle velocity. A radar chronograph tells how fast the ball is going when it leaves the barrel. It uses the same technology that Officer Smith used when he wrote you a $400 speeding ticket. Only now, it will make sure you don't leave a black welt on your friend's leg.
Industry standard is 300 feet per second (you should not play any where they don't check the velocity or where they let you shoot over 300fps). The most distinctive chronograph in paintball will also show the rate of fire of your paintball gun when you fire a string of paintballs over it.
The "Big Blue" Chronograph is durable enough to stand up to the test of being shot thousands of times with no damage. Everyone's done it, and chances are, you're grinning like an idiot right now because you just remembered the last time you did it. Big Blue will last for years, through rain, shine, tournaments and all day events.
It uses large 6V batteries (not included), which are sure to test hundreds and hundreds of velocities before they need changing. The very simple design is just one large button to turn on. Simply shoot over the top of Big Blue with your paintball gun and it will scroll out a reading within seconds. Big Blue is so sensitive that you can even shoot your paintball gun near the top of it and it will depict an accurate reading. In case your paintball gun shoots over 300fps, a shrill beep will sound, making sure that every player within earshot knows to stay away from the muppet at the chrono.
