impulse with blade trigger,halo b,WAS board and new designs bolt n' hammer.
It shoots very fast. The eye is unbelievable. It's less money than SP vision.
Not too complex but kindof hard to figure out how to work.
This board allows you to adjust dwell, debounce, bip delay, eye mode, rof, and eye sensitivity. It is hard to find what setup works best because of all the stuff you can adjust. Other than that this changes everything about the gun. I can shoot so much faster than before and I never break paint in a game. I recommend this to anyone who never wants to chop paint and shoot very very fast.
Buy this if you have an impulse. Once you have it set, you'll love it. I'm not giving it a 10 because of the installation.
