I'm a new owner of a GMG Daniel Boone. Cooking two 8lb pork shoulders today. I decided to check grill temps with an independent thermomer. Using an Ivation IVA-WLTHERM. I'm getting some wierd reading and was hoping for some help. I have the gmg set at 225. The Ivation reads 214 when i set it on the left side near the gmg probe, but reads much higher everywhere else. Around 240 to 245 in the middle and the right side. The ride side temp also seemed to swing alot more 235 to 245. I have the probe stuck thru a small potato.
