It connects in-line with your pump to automatically limit the pressure of the launch.  This allows you to make much more repeatable launches, great for more consistent results.  Perfect for use in an altitude or launch distance competetion.

No tools needed, comes pre-assembled and pressure tested.

To adjust the pressure, pull upward on the black cap, rotate the cap to increase or decrease the pressure, and push down on the cap to lock in that pressure.
