I can't disagree more.

Last I heard a human at rest would produce app. 100W.
Some of the heat would be disposed of as heated breathing air, some by air heated by skin contact and some as blackbody radiation.
I have had the opportunity to handle some really fancy thermal binoculars and seen the thermal signature of a...
The wrong item is kind of outside of contract, the seller have just accidentally mailed some of their property to you. It is still their property and you should return it on their expense, if they desire so.

My signature contain a link to Odicforce, it is in the UK and carry good quality products.
Don't forget goggles for anything above 5mW.
They tend to cost more than the laser, and if you don't want to spend that much get...

Odicforce is in the UK.
