I installed mine as close as possible to area where I normally cook is.
In my case that was level with the handle, just to the right of it
I may install another one on the other side, but after using it for a few cooks while monitoring other areas with the maverick I have a good idea of what temp they are at compared to that gauge.
I I load it unusually with meat I just use the maverick to double check different spots to know where they are at
