whichever one you use, you need blower wind speed if you use it for putting out a fire..

The blower is by far the most effective fire fighting tool available.. It will put out a tail pipe fire right now with no damage.. it will put out an exploded motor with fuel burning inside the jet.. It happened to me.. I had the fire out in 10 seconds. I put a brush fire out with mine once. a few crashes too.

My fireman buddy says its like opening your mouth at 90 mph in the wind.. it stuffs the fire.

I cannot recommend having a blower enough for jet flyers.. cheap insurance.
