Just assemble the Smoker and have completed the Seasoning exercsie. The Temperature Gauge was off by 80 to 100 degrees. I noticed the screw (slotted) on the probe (dead center) of the gauge and was able to adjust to exactly match to an kitchen oven rack temperature guage. It took a few tries but it was during the seasoning phase and no harm to any valuable meat. Once adjusted at 250 degrees I verified the accuracy on the lowest temperature as well as the highest I was able th achieve and I was spot on. If you have the same slotted head on the probe part of the guage save your money for some nice accessary for your smoker and take a screw driver in hand and tweak away. Seems to work fine now.
