My Experience Using The Portable Propane Heater

My Experience Using The Portable Propane Heater

After nearly freezing to death in my stand last two winters, I vowed, “Never again!”

Last year, I purchased this portable propane heater and 8 Propane cylinders and put them in my stand well before the season started. I walked to my stand at 5:15 AM at a 30 deg temperature. I cannot be super cold for some of you, but it is plenty cold for this Texas boy. I climbed into my 4×6 stand and the first thing I did was start up the heater.

I screwed in a canister of propane, pushed down the pilot, and lit on the second try. Pushing the control knob, I turned on the heater and placed it on low, and sat back.

After 5 minutes, I removed my jacket and a long-sleeved thermal shirt. After 15 minutes, I was toasty warm. Then it is now a great company during the camping of my stand.
