When to use discrimination?

[Justadad1999]

When hunting in city, county parks, soccer, baseball fields, do you recommend hunting in discrimination mode OR all metal mode?

If you are a coin hunter you want to use quite a bit disc, if you are looking for coins and gold jewelery you want to use some disc to get rid of the nail, small alum foil. Now if you are a relic hunter than you may want to run all metal. If you have a tone ID detector you also can run all metal as iron will have low tone. I have a Sovereign GT with tone ID and I run with no disc( will disc out iron at no disc.) at all and go by the tones. This is the same with my Explorer as it too is tone ID and I will disc out some of the iron. My X-Terra also are tone ID so I can run with no disc. Myself I could not run a single tone detector in all metal for parks and school hunting as you would be digging all the time or looking at a meter, but with tones you can tell when you go over a metal target.

It probably would have to depend on what type of detector you are using. The more expensive detectors are fairly accurate in their discrimination, and at the same time are great on depth. Unless you are in an area of silt, discrimination would be the best way to go for those places you mention. Run your discrimination at a setting you are comfortable with... the lower the better.
