Easy question - temp gun

I don't think my temp gauge is accurate. I have a heat temperature gun. where should I point it to get an accurate temperature reading?

You can only get an approximate temp reading. Temperature sensor is inside the coolant system.

I check the thermostat housing and the start of the upper hose from there and the temperature sender and area around the temperature sender its self and use the hottest temperature I get.
