How to Use The Cesaroni Pro-DAT Tool


What is the Cesaroni Pro-DAT tool used for?
The ProDAT tool is used to modify the delay time of the Cesaroni reloadable motors so that you achieve parachute deployment at the perfect time during the flight. Basically, it is used to drill a hole to a pre-determined depth into the delay element (called the delay grain). The deeper the hole, the shorter the ejection delay.

All the Cesaroni reloadable motors have a long ejection delay on them. With this tool, you shorten the delay time to get it to the best one for your rocket. The tool works with 38mm, 29mm and 24mm motors (Adapter Ring is required for the 24mm and 29mm motors - it is sold separately for each).
