I know for most cooking on my RT-700 I have no need for an infrared thermometer. However, I just added a Grilla Grills Primate gas grill that has a griddle (use griddle mode or regular grates). I've watched some videos of folks using griddles and it appears that knowing the temperature of the griddle (by zones) is important to what you're cooking...no different from using a Thermopen for smoking...or grilling with the RT-700. I've read some reviews of infrared thermometers and I'm probably more confused that I was before I started my research. Now, I'm trying to figure out whether I need a "K" type sensor or a "T" type sensor. Does anyone out there use an infrared? I'd love to hear how you use it and what you like or don't like about your make and model. Thanks.
