Rob Ellis here from Fairfax Virginia. I got started detecting underwater in the 80's with a Whites PI 1000. As a SCUBA instructor, I wrote the first underwater detecting specialty certification course. While I still do a lot of underwater detecting, I also have a lot of experience on land. Although I do the occasional relic hunt, my favorite kind of detecting is finding lost items for people (https://theringfinders.com/Rob.Ellis/). I have too many detectors to list, but somehow I have found a reason to keep them all!
I recently had a AARP article about me and another detectorist, https://www.aarp.org/money/investing/info-2023/metal-detecting-for-fun-and-profit.html.
