.....and available for about 3-5 grand, less on used units. It is "Infra-Red Thermal Imaging" cameras. If is far superior to just std I.F. or night vision by allowing objects even slightly warmer than its background to be visually detected over a wide range of ambient temperatures!!! It comes as a hand held video type camera (or helmet mounted version used by fire and military). Logic says its potential use in treasure hunting is to wait until late afternoon until the surface dirt, rock, etc has cooled off somewhat, most models will automatically adjust the internally cooled CCD device to detect the hottest parts of the ground (or the warmest object in any environment) where metallic items (coins + relics) that are slightly warmer, due to releasing the residual heat collected during the day over a longer period of time, will create a warm spot directly above themselves. Since no discrimination ,other than its physical size, is available yet, one could use it when foliage is minimum or nonexistent and find old sites just by the shear quantity of hot spots visually seen through the camera while walking in a plowed field, along a creek, in a large grove of old trees or large expanses of forest, etc and then use your detector to identify each warm item!!! For more info, see www.X20.org/thermal for the current cameras available now. Hopefully as fire departments buy them to detect hot rooms behind closed doors the price will come down. Anyone who can afford to buy one now or split the cost among several of your favorite partners should give us all some feedback on its effectiveness. I predict it will become the hottest tool for detectorist and archaeologist to find sites that no amount of research or eyeball reconnaissance would locate as soon as the word spreads!!! I'm saving up for mine now!! Happy Trails always, JD
