To make metal detecting in Oregon even more difficult, you need to be aware of another law, The National Historic Preservation Act - NHPA.
The easiest way to understand what these laws are about, is if you are detecting in Oregon, especially on State Land, do not dig anything that you believe is an artifact, or anything that is older than ugh 100 years.
If you want to detect on private property, then be sure you get written permission from the landowner.
For detecting in Oregon, town, village and city parks, you'll need to check with those local officials.
I cannot be responsible for any outdated laws from the time of this posting.
Do Not Quit The Hobby
There have been people who commented to me that they are fed up with the laws that impact our hobby. So they have decided to quit. If you are considering giving up on what is probably the best hobby out there, I am asking you to reconsider your choice.
What good does it do the hobby if people begin to leave? By so many quitting, then the beauracrats win, because that is exactly what they want us to do.
There are so many areas to detect if you just research, and ask for permission of private property owners. I have hundreds of sites with permission that I will never be able to get to. You can do the same. Don't give up!
My Metal Detecting TV Series Was Watched Closely By The Archaeologists
I was the first to film a reality TV series about metal detecting. However, the Archaeologists did not like the idea of me showing viewers how to dig artifacts. So they went into attack mode against me. More information here.
