THE SAFEST WAY TO APPLY FIRE
We’ve sold numerous Pulsefire systems to the general public, firefighters, farmers, controlled burn prescribers, and members of the U.S. Forestry Service. While the UBF is focused more on novelty, it’s still capable of typical long range torch use.

FREQUENTLY ASKED QUESTIONS
Most of the FAQ answers relating to the Pulsefire® LRT also apply to the UBF.
Not that we're aware. We tested extensively with a SCAR chambered in .308, a firearm configuration known for being harsh on attached devices, and experienced no failure. We've seen it attached to a .50 BMG and operate without issue.
Not that we're aware. We've had it attached to numerous short barreled firearms without issue, and so have our customers. We have a shield above the unit that helps deflect the blast.
In order to comply with regulations and avoid requiring permission from the state fire marshal, pyrotechnics license, etc., the Pulsefire LRT is equipped with a short range nozzle. See more details here.
Unfortunately, the same nozzle installed on the Pulsefire UBF results in a very hot flame right by your hands. It is not a comfortable experience. Since the LRT isn't a big seller in California, we made the decision to not sell the UBF in California. You can always install the short range nozzle yourself if you have a standard UBF.
























Loved it after I got finished with it. Just need backpack
Well that’s an interesting mod lol
This is an amazing company. They have been so easy and effortless to order from. I bought my husband the LRT Pulsefire for Christmas and he loves it. One small issue with battery and they replaced instantly without any hassle! The man I talked to when I ordered was so kind and respectful. Highly recommend!
Love it, works exactly as advertised. Useful and fun
Every pyro needs one of these! Love it!
I have purchased more than one slinger from exothermic, and could not be happier. Great job and thank you for a great product.
