With the X15, both the fuel and CO2 go fast. It’s not a problem if conditions are good, your field is ready to burn, and you’re easy on the trigger. But if you’re trying to melt a wet stump, expect to spend some money on fuel. At the end of the day, you can burn a field just as effectively with a drip torch and save on the $1,600 that an X15 will set you back. It just won’t be nearly as much fun.
