In theory the 3 kHz should work best.But I’ve found The 7.5 kHz to be great at coins.I never saw any advantage to the 3 kHz myself,aside from the digger coil being 6 inches and better separation.
The 10.5dd my coil is great tho,it’s deep,great separation and Not bad to swing at all.That Coil would be my choice.
The 705 is a excellent machine,it’s so feature rich I can’t believe more people don’t use them.

The lower freq. is better on silver but The mid freq. is a good general purpose coil, If your only trying to find silver I would say try out the 3khz

The 3khz might hit harder on high conductor coins, but it might not separate to good.
I used the 18khz on mine, but i was hunting small low/mid conductors which it was very good at.
It's a nice quiet running machine and it didn't suffer much from iron wrap from memory, probably a lot of signal filtering going on at the top end of the ID scale though.

I have a Coiltek 3 KHZ 6" coil that works good for silver and it separates good.
