600 bucks, is this the first time you have used it?
There is a three-position switch: fan only, off, fan + cool. It is on a coiled cord, one end of which is a coaxial connector for power, the other a three-pin connector that connects at the helmet. The coaxial connector pulls apart easily, for those times you forget.Hopefully it will be just what you need for those brutal days. Is there a on/off switch or is it just on when plugged in? Just curious.
