Dwell: LED solid
Dwell is the amount of time that the solenoid remains open (measured in milliseconds, or ms for short), which translates to how long the bolt will stay forward. This determines the length of time that the marker's valve will release pressurized air to fire the paintball. Increases in dwell will generally increase your velocity as well, though there are working limits to this.
Dwell is adjusted in half-millisecond intervals, starting at 8 milliseconds. This means the lowest setting on the board is 8-ms, first highest setting up is 8.5-ms, then 9-ms, 9.5-ms, 10-ms, etc. The stock dwell setting is 52 blinks from the bottom (34-ms). We don't recommend you adjust the dwell unless you wish to spend time and air fine-tuning the marker to possible receive better performance. If you accidentally adjust your marker's electronics and now the gun doesn't fire, readjust the dwell to 52 and try again.
