Speedball
paintball markers are designed to be small so they do not present a large target; in virtually all tournament rule sets, a player is eliminated if they, or anything they are wearing or holding including their marker, is hit. Tournaments also specify allowable firing modes and rates of fire. For instance, PSP league rules place a 10.2 (balls per second) limit or "cap" on rate of fire, but allow a marker to "ramp" (shoot additional shots per trigger pull) when the trigger is pulled rapidly. In the NPPL, paintball markers may not fire over 15 and the firing mode is semi-automatic (one shot per trigger pull). The circuitry of modern electro-pneumatic markers generally incorporates specific firing modes that follow each league's basic rules. Beyond regulations to rate of fire, some paintball markers use anti-chop "eyes" to prevent the marker firing without a paintball securely seated in the chamber. This ensures that a paintball, which has only fed halfway, is not "chopped" in half as the bolt closes the chamber, which will affect accuracy of subsequent shots due to paintball fragments left in the chamber and barrel. Modern speedball markers tend to be electro-pneumatic in design, and run off compressed air or nitrogen. Slightly older models of speedball guns used to run mechanically, but higher rates of fire could not be reached due to longer trigger pulls and heavier pull weights. Electronic markers replaced the often heavy and long pull of a mechanical trigger, needed to manipulate the mechanical linkage to the firing mechanism, with a simple electronic button or other sensor that detects a trigger pull. As a result, electro-pneumatic markers' trigger pulls are often measured in millimeters of travel and just a few grams of pull weight, allowing for very fast rates of fire using various techniques of "walking" the trigger (alternating pulling the trigger with index and middle fingers). The technology of speedball markers has been advancing over time. Every year companies make guns more consistent, accurate, reliable and convenient. Although this technology can become costly, some players are willing to invest large amounts of money into their markers. The advancement of technology in markers also means that less-expensive technologies, usually based around the circuitry of a marker, can be integrated into lower-cost markers, making entry-level speedball markers very competitive in many ways to higher-cost models. Also, as markers become more advanced, hoppers must also be able to keep up with the achievable high rates of fire. == References ==
