I've always been hesitant to camp/sleep in a portable, running the heater all night, but it seems like camping in portables has been more popular recently. I've watched a few Youtube videos of different anglers doing it.

I'll put a plug in for Jay Siemens, I enjoy his Youtube channel and has a couple camping in portable video "how to's" and is where I got the idea, if anyone is interested.

Does anyone fish with a Carbon Monoxide detector in their portable, either during the day or camping through the night?

If so, are their any specific units anyone would recommend, that work well and are mobile?

I haven't made it out yet, but at some point I'd like to try. Most Carbon Monoxide units are cheap, so I'm going to snag one if I ever do try and camp, but will probably bring it along every trip, because why not?

I agree Jay has great videos.

I used them anytime I used gas heat. I have two in my skid house, even though I have a vented heater. I use them in the hunting shack when using the big buddy.

I do not use them in the portable during the day.

They run on 2 AA batteries. I don't have them handy to let you know what brand but it was the portable option at Menards. I think this is the same. https://www.amazon.com/Kidde-KN-COB-B-LP2-Carbon-Monoxide-Alarm/dp/B004Y6V6K4/ref=pd_lpo_60_img_0/146-2621074-0026941?_encoding=UTF8&pd_rd_i=B004Y6V6K4&pd_rd_r=da5e516a-2d08-43d3-9344-ae79ee8cbbf6&pd_rd_w=N9np1&pd_rd_wg=BVvHc&pf_rd_p=16b28406-aa34-451d-8a2e-b3930ada000c&pf_rd_r=QMTMZW7GWW4834J0J2QE&psc=1&refRID=QMTMZW7GWW4834J0J2QE

I just ordered something similar. Probably quite a few out there that work fine. Might order a 2nd for a backup, just in case. Thanks

The other thing that I've read in my short research is to make sure to have the detector the same level as your head, since CO is more dense than air.
