If using sunflower mr. heater...lots of ventilation in 2 man shack, cuz it's get's hot hot hot, even on lowest setting.

What kind of shack are you in?  I fished out of a home made portable, and had a problem.  Also I fish out of a Yukon with the vents open and have had no issue.  Best way to know for sure is to get a CO detector in the shack.

In my 2-man portable I usually have the bottom of the door unzipped some and the vents open at a minimum.  Sometimes I will have side windows open as well.

If you have the Buddy or Big Buddy, I believe they have a C02 censor and will shut off if the co2 levels get too high. I think this is why most people buy them.

im in a little 2 man shappel just was worried about the co2 or co whetever its called  the alarm sounds like a good idea

[Melbs7]

CO is what you would ahve to worry about in that situation.... not CO2

[icefisherman309]

yea i meant co

I have a Coleman heater that is also supposed to have a low-oxygen shutoff.  I have a 2 man icecube that has a built in vent on the roof.  Used it many times without a problem.  One day I suspect I had a problem as I strted getting a headache and didn't feel that great.  Off with the heater and out the door- much better.  I now make it my practice to turn off the heater and open the door for a couple minutes every 1/2 hour to hour- just in case.    Most of those heaters get so warm so fast that a couple minutes isn't a big deal.

23 bucks for a digital CO sensor     Cheap safety item in my estimation.   I just picked one up last week

Not true! They do not have a CO2 detector on them!

that's right muddly, they don't have the CO sensor on them, its called the low O2 sensor............low O2 and the heater wont fire up and run until more O2 is introduced into the environment that the heater is in.

Sorry, I was mistaken. I knew it had a sensor on it but just got it backwards and yes I did accidentally put co2 instead of CO so I was basically wrong all the way around. MOoks

The only sensor on the buddy heater is the thermal coupler and pilot light.  It's basically the same on many gas stoves.  Other than the tilt sensor.

I purchased my Big Buddy this fall and imediiately tore it down to remove the tilt sensor and there is no CO sensor in the unit. Nor was there anything that said it on the box or even implied it.

http://www.mrheater.com/product.aspx?catid=41&id=116   some specs on mrheaters site about the buddy units.  says it has low oxygen shut off system and tip over shut off switch.   this is what we use in our shack and have not had any troubles, but we also put a co detector in it as well just to be safe.

Well all flames do go out when there is no oxygen!
