Do I need a grill thermometer if my grill has a built-in one?

Yes. Built-in lid thermometers measure air temperature at the top of the grill, which can be 50-75°F different from grate level where your food actually cooks. A probe at grate level gives you the real cooking temperature.

How do I protect probe wires from grill heat?

Route wires through the lid gap -- most grills have enough space. Avoid letting wires touch grates or flames directly. Wired probes are rated for temperatures up to 572°F ambient, which covers virtually all grilling scenarios.
