MidTN, best of success with your new F-75.
I have several detectors, each with 'assigned duty such as hitting Tot-Lots, urban Coin & Jewelryp Hunting, and those for some get-serious Relic Hunting in dense ferrous debris.
With my health issues and limited mobility I can't hunt like I used to, and didn't really need two more detectors, but .... In the last two weeks I got an as-new Tek. Patriot. Friday I ordered a 5" DD, a 6 1/2 elliptical Concentric and elliptical 10" Concentric which all work on the F-70 / Patriot as well as an F-75.
I had two F-75's in the past dozen years, but for what I was doing the T2 and others i had were working for me. I had my last one in 2016.
I was thinking about new stuff and reflecting on some I might like, so I got the 'Sidekick' unit, the Patriot, and then the coils I wanted, and now I should have the 'Primary' model by the end of the week as I ordered an F-75+. I look forward to putting this 2-Detector Team to work soon.
I'm curios about your field performance with the 6 1/2 Concentric with your Patriot?
