HOW TO LOCATE METAL DETECTING HOT SPOTS. (In 4k) Please note that this video is four times the video resolution of standard Broadcast Television and places a huge demand on technology resources. This is best appreciated on a large 4k Television.
However you can watch this because YouTube automatically adjusts picture quality to optimize viewing on a computer,- go to the gear symbol bottom right of video picture (view settings) and select 4k to see if your computer or television can run this video at full capacity. I also recommend watching this on a large 4k capable Television and see its true capabilities.
