The XP 310 is a long range multitank varient of the air pressure system. It has a nozzle selecter that has four nozzles of varing size. Like the argon, the pump shaft on the XP 310 rotates. The XP 310 has a lot of power and output. The pressure guage is highly useful and conveintly placed if you are right handed. The pump handle is shaped in such a way that the user pumping hand is perbinditualar to the ground. The XP 310's two pressure chambers hold a good amount of water. The clear reservoir is quite useful because it allows the user to determine how much water that there is left.
