A new way to find new caves ***VIDEO***

[Pegasus]

Camera arrived and in use.
Already found a contactor about to go into meltdown. That saved a possible weekend call out. It's nearly paid for itself already.
Now for that Nidderdale master cave on Sunday.

Great, good luck with that master cave!

Would you post some photos of your cave hunting exploits please??

In Matienzo this summer, I used a Flir One infrared camera attached to an Android device with successful and interesting results which are documented on the Matienzo Caves Project website: http://www.matienzocaves.org.uk/science/IR.htm
The main conclusion is, although cool places on the hillside may give false promises, a cool draughting hole will show a trail of cooler vegetation below and beyond.

Here is another wintertime example. This was a school project and quite successful. The cave wasn't really interesting but the camera did an excellent job of showing warm blowholes. I helped on the dig (and might be in the video) and was inspired to get such a camera. Too much money though at last check, the one used here was purchased by the university.

A friend of mine took a thermal camera down to the riverside at Matlock Bath and tried one of the locations where there's supposed to be a sough tail. Even though there's not much apparent to the naked eye, the thermal camera clearly showed the warmer mine water emerging from the bank and flowing downstream.

Water will emit much more thermal radiation than air, and so be much more visible.

If you have a draughting cave, you might see the effect on the surroundings i.e. warmer/cooler grass/rock surrounding it; as others have said you are very unlikely to see the draught itself.
