I have heard that the mounted thermometers that come with most smokers are notoriously inaccurate. However the one that came on my Masterbuilt was pretty accruate. +/- 3 degrees against my Maverick and when I did a boiling water test. I say it 'was' accurate because it has stopped working altogether. Are there any good replacements out there? I have looked at Old Smokey brand for about $15-$20 and they had some good reviews but mostly ease of installation etc. I didn't see anyone who reviewed it vouch for it's accuracy. I use 1 probe of the Maverick to monitor the smoker temp but if I have 2 pieces of meat in the smoker I need both probes. I would like to be able to read the smoker temp easily, I don't want to buy another remote.
