MEGABOOM STS is a fun way to practice your crossbow skills while making some big time noise at the same time.
The MEGABOOM STS Target System consists of a base which is basically a pressurizing device that allows you to pump air into standard 1 or 2 liter plastic soft drink or water bottles. Once pressurized you simply set up the target and take a shot.
If you hit it you’re going to be in for a boom, of the supersonic variety. The impact of your crossbow bolt will cause the bottle to rip open at supersonic speed, resulting in a small Sonic Boom (up to 150 DB) and can be heard for up to three-quarters of a mile.
