Tippmann Sports has launched a groundbreaking new marker powered by propane The company´s C3 with PEP Technology is a pump-action marker offering a new level of convenience with the same range and velocity performance as CO2, nitrogen and compressed air. The propane fuel source behind the C3 is much more accessible and considerably less expensive than traditional CO2. In addition, the new marker´s PEP Technology (propane-enhanced performance) is not affected by temperature changes and offers users significantly longer play. In fact, a single 16.4-ounce standard propane tank provides more than 50,000 shots as compared to a 20-ounce tank of CO2, which offers roughly 800 to 1,000 shots.
