what do i get. they make so many kinds. witch one is the best.also they make them pre set to either 450 psi 800 psi or 850 psi. and either high pressure or low pressure. what do i do.
Need a little more info' than that mate.
Some markers (ie Angel speed, A4's) require a low input pressure. Others need a higher input.
What marker are you after putting it on?
As long as your marker has an inline regulator you will be able to use it fine. if you have an autococker it uses low pressure, but is recommended you have a high pressure tank so you dont get a drop off of fire at high fire rates.
