What does the heater pad do.

WOT switch! Also get a heater pad.

In a nutshell the heater kicks on when your bottle preasure starts to drop. When it heats the bottle it allows your N20 to stay in liquid form longer and keeps noids and valves from freezing. If you ever shot a C02 painball gun alot and the bottle gets cold and the gun starts to freeze up... same principle except if it breaks somthing, its not going to be a 99.99 paintball gun <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
