Depth is not a factor @ silver in turf ? Seems to me that most parks the silver is indeed deeper than clad (on average). Sure, perhaps not "so deep that they're beyond ability to detect".
Yes, the '70s/80's "silver rush" era did indeed hammer many parks for their easy gimmees. And yes, those particular hammered parks will be a tough nut to crack today for newbies, to eak out any more. One thing that will help, is to avoid digging shallow clad. Yup, mentally reject all shallow. I know that some people might say to "get it out of the way" (masking) or "clad adds up $$ after all", or "you might miss a shallow ring", blah blah blah. But at the end of the day, here's what starts to happen to those persons digging all the shallow clad: Their brains become subconsciously tuned to all the loud "bongs". And pretty soon, they're simply not hearing the faint whispers. So rather than ending up "getting the best of both worlds", you end up spending all your available time just digging clad. D/t that's what you subconsciously start favoring/hearing.
