Leading the flamer industry. Our dual orifice burner will not flame out! If one goes out the other reignites the one that flamed out. So you will not come to the end of the row with a cold burner and a row of untorched weeds. Designed by an organic farmer. If you plan on building a broadcast flamer to flame row crops, we recommend 3 per row. One on the right of the row, one over the row, and one to the left of the row. Then once the crop is tall enough, remove the burner over the top of the row and turn the right and left burners to shoot the flame under the rows.
