long range lazer thermometre pistol

[BENZINAS]

is it possible with a pistol like that to find a sealed cave etrance looking only the temprature numbers , is it possible to take a diferent temprature number when we pinpoint with lazer on the sealead etrance which has empty space behind rocks and when we pinpoint next to the etrance on a simple rock , is it possible with tha same way to find a underground hidden room when we pinpoint to the ground and see if temprature changes ? wait for your opinions !

Hi.
Before years i made many tests with a thermal camera without results. Max detecting depth was about 20cm for a very big object only 3..4 hours after noon. Device read the temperature at up side of ground not at lower.

i'm talking about this simple device , someone told me that you can see diferent temprature above a bunker and next to it , ground temprature is diferent when underground there is a hidden room , has anybody test that ?http://www.google.gr/url?sa=i&rct=j&...69283674575328

The ground upper the hidden room must be 10cm max so to see a temperature difference of 0.1degre of celcius.

Thermal scanners can be the best selection.
They are a little weaker thermal lens cameras.
