OK, so I found this "what a deal" MES 30 Gen 1 (no window) on Craigslist locally. Couldn't pass it up but now I'm questioning that. Extremely clean inside with signs of very little usage. So yesterday, I ran one of my Maverick 732 probes down the fully opened vent on top resting the probe next to the MES's probe. Both probes clean. Fired it up starting at it's lowest temp setting of 100* Lower feed tube was open about 2". Once the MES reached 100, the heating indicator light turned off and I watched it climb as noted below: MES temp gauge Maverick 732 102 133 113 143 120 145 126 151 Since the lowest setting for this MES is 100 and based upon the Maverick 732 telling me it was temping at 151, I am stuck with the lowest actual temp being around 150. Not good if one wanted to do fish, etc. Is there something that I could have done differently? Is it going back on Craigslist tonight?
