This is all such great information. Thank you all so much. ....
That's ok. You'll get our bill in the mail
.... I have a minelab safari and a Tesoro sand shark. Which would you prefer to use on the beach?....
I don't know about your particular beaches. If they are nasty mineralized (tell-tale gunpowder grey-ish /black) perhaps you'll need that sand shark pulse. But otherwise, I dislike pulse, d/t you can't reject nails. Other than 2nd-guessing tones and guesstimating on double vs single beeps, etc... So I prefer a discriminator. But that's just me. Other people love pulses. You might go bonkers on a nail-ridden beach though.
As for the Safari, I'm unfamiliar with that one's ability on the wet salt. If it's anything like the Explorers or Sov's or Excal's abilities: that's what I'd choose. But again, that's just me. Others love pulse (nice sounds, easy to use, hacks all minerals, etc.... )
.... Also, is there a good chance of finding old silver coins and things like that?
Depends on if the sand being cut into and eroded is old sand, or new sand. By "new" sand, I mean sand that "came back in" in the recent decades, during a spring/summer in-fill. And if that sand "came back in" with no older targets coming back in with it, it would be "sterile" sand. As such, it would only have coins from the decades since it got there.
Versus if the sand being cut into has been "high and dry" for 50 or 100+ yrs, then yes, it can have old coins in it. Way to many variable to answer that question easily. I've worked cuts with 300+ coins in it, where every single one of them was new. But it's still fun, because anytime you're getting metal targets on a swim beach that fast and furiously (albeit only new coins), is when the odds exist for rings to be coming up in your scoop. Especially if you start finding fishing sinkers , that means mother nature is grouping heavy dense items in her patterns.
