Fisher F75 a metal detector for gold
This is a short demonstration on the discrimination capabilities of the Fisher F75 metal detector. This detector can discriminate between different metals giving a unique reading measurement for each. This is useful on gold fields that contain a lot of junk metal as you can discriminate out other metals and the Fisher will tell you if your target is gold or something else.
