I've got mixed feelings on this.
On one hand, I really like the idea of reducing the number of hit animals that get lost in some way or another.
On the other, this seems way too easy to use for the wrong purpose. Heat-seeking is not on my list of fair chase practices.
I've had a chance to poke around with one. As an engineer I thought it was a nifty idea and technology. As a hunter I was wary of it. All I used it for was to look at how cold my fingers were compared to the rest of my hand (Raynaud's) (and it was kind of cool to see the cold patches my hand left on everything), and to locate my hand warmer that I'd dropped on the floor of the truck.
The sensor resolution is something like 160x220 (around 1/4 the pixel count of a standard-definition TV
[edit, see below]), which in my mind limits the product's usefulness to the intended use, recovery. Make it better resolution, and you increase the benefit to somebody trying to use it for live game finding.
I don't see a good way forward for this product. I would be at least a bit happier with the product if the Leupold product page didn't have the image of a (presumably live) standing deer as an example use.
Edit: Product spec sheet has the resolution at 206 by 156 pixels, putting it at 0.032 megapixels of resolution. Compare that to American SD TV resolution of 640 by 480 (0.307 Megapixels). 1/10 the pixel count. Still enough to get a picture, but seems unlikely to me that it would be practically useful out to 600 yards like the product page claims.
Edit 2: See product brochure (here:
https://www.leupold.com/wp-content/uploads/2016/10/LTO_WelcomeGuide_AB.pdf) for a better explanation of what they want it to be used for. This frames the product better than the sales page. (Well, kind of.)
