Will laser heat sensor find inadequate battery cables?

Just curious if I can use one of those heat gun devices to detect inadequately sized battery cables and connection points in my solar system? I'm only getting 15 minutes of run time on my 1200watt ...

A 2000w inverter should have a minimum of 1/0 cable to the battery with a short 3' run. With welding cable (flexible) 2/0 and larger is relatively easy to work with, and will allow slightly longer runs.
I have no idea how much heat would be generated at those loads with a x.x volt drop, but I do know the actual voltage drop can be accurately measured and expressed as a percentage.
