In the Amazon HT-18, Best Sellers in Thermal Imagers is the 12th, the price is $388 . HT-18＋ , the price is $299. I think HT-18＋ has better image than HT-18.

The camera has wonderful clarity and the detail level is very good. The B&W photo attached was taken in complete darkness. The different color palettes you can choose from make it very useful and the way you can blend the thermal and optical images at different intensities is amazing. There's one photo of my heater with no thermal and one with no optical. The no thermal still points out the high and low temps. The no optical is completely heat driven. I added a couple more in different degrees of blending. The star of the show though is the software that comes with the camera. You set your palette and blending on the camera and take a picture. But once you load the picture into the software, you can change the palette and blending anyway you like. All the data is apparently there and the software lets you check the picture out in any variation you like. Once you see the best way for whatever you're doing you can then adjust the camera to the same settings so it's more useful for that task. The attached video is an example of that. I just got it today, read the manual, and can use all the features. Love it already and I haven't done my home heat analysis yet!

I will use it well ~~!!!!!!!!!!
