This is a good dual sensor thermometer and timer I have had mine for 3+ years holds up vary well.
Polder Dual Sensor Thermometer and Timer Reviews
Pros: Pit and Meat Temp with one probe
Cons: Probe malfuntions
This is the second dual probe thermo that I purchased. The first was a CDN. Both probes went haywire on me after 5-6 smokes. I protected the probe wire with foil always. From now on I will be sticking with the Maveric dual probe units.
