This is my first time dealing with or using a thermal imaging camera, but it was very simple to use and it helps me send images to customers and keep them updated regarding issues as well as the initial diagnosing review. I have used this camera for automotive repair work as well as giving customers an estimate in regards to home insulation cost. There are 4 various modes: 1. 200W visible light 2. Picture in picture 3. Thermal imaging 4. Thermal fusion. I rarely use picture in picture mode. The other features that attracted me to this thermal imaging camera were the rechargeable li-on battery and the 64G built in SD card. (I don't like disposable batteries because they always need to be replaced, and removable sd cards cost extra money). So in conclusion this thermal imaging camera not only saves me money, it keeps my customers informed, and saves me money. I definitely recommend this camera from the do it yourself individual to a business professional.
