OK. So I sold my X-70 4-5 years ago and got a Sovereign GT. The GT is a very good machine but, I couldn't mesh with it because of it's bulkiness. So, I recently sold the GT and have been using the AT PRO. Which I like a lot. However, I have never forgotten the sweeeet music my X-70 would make when it detected a silver coin. Ahhhhhhh, man. Hmmmm...705 and a PRO. I could rule the world!! I should have never clicked on the X-Terra page!!
