to the best of my knowledge heres what it's got:
1: semi auto - caps at around 15bps
2: psp ramp - caps at 20bps, achieves 20bps ramp after 3 consecutive shots
3: auto - achieves 15bps fully auto after first 3 shots
4: millenium ramp - once 8bps is achieved, marker fires at 20bps in ramping.
that said, you can adjust the rate of fire, balls per second and dwell to meet tourny standards. Main Mode 1 is Rate of Fire (the options above), Mode 2 is the balls per second, and 3 is the dwell.
it's fully customizable with the stock board; very slick too. bad *** marker for the price for sure.
