This is the online store for the Speed Demon - a "speedometer" for your speed bag.

The Speed Demon's digital display can tell you how fast you are punching (punches per minute), the number of punches you've thrown, or motivate you with its challenge mode.

If you are serious about speed bag training, or just want a reliable way to measure your speed bag workout, the Speed Demon can help.
