A standard Stabilizer has about a 70:1 ratio.. That is plunger size to high pressure output hole. Generally the bigger the reg is, the better is works.
Greater ratios allow for better consistency throughout the full pressure range of the tank. 1/5 of the plunger surface area has regulated pressure applied to the opposite end of the plunger. Therefore it cannot be as consistent as a Stabilizer.
The bucket takes about 3 turns to remove. "Same as a paintball tank"
The adjustment is on the top of the reg. The reg can only be adjusted while removed from the ASA/gun/device/ or whatever you may have it attached to.
The air chamber size is the about the same as a micro rock.
