I use this thermal camera for multiple purposes. I use it tracing electrical, plumbing, and for diagnosis on vehicles. The camera turns on quickly, feels good in my hands, and is easily operated with one hand. It comes with a SD card so that you can take images of what you're looking at, so if you need a larger image, you can save it for use on your computer. The display also shows the coldest and hottest spot in the area, which comes in useful, and the color gradient for temperature is easy to see. The battery life is excellent, and it comes in a quality case for safekeeping.
