Carbon Monoxide and Propane Sniffers

[Meerkata]

I have recently installed a diesel heater, and decided that I should get properly equipped with both CO and propane sniffers.
Then I read the very recent info from members, which of course totally confirmed my decision.
What I dont know is what to buy. Are household CO sniffers good enough, or should I get a "marine grade" for quite a few $$ more?
On propane monitors, are there any that are better, or does anyone have preferrance(s)
Thanx

Jim, what type of heater did you install?

I can give a "thumbs up" for Xintex's tech support...

My heater is an Espar Airtronic D5.
