XT70 Coils Question

[Jerath]

Helo everybody, I'd like to ask you for an opinion about a coil exchange.
I received an offer to exchange DD M 7,5 kHz 10,5" to a concentric H 18,5 kHz 9".
Both of them are in good condition and I'm wondering which one's better.
I also own DD H 18,5 kHz 6" and a standard concentric M 7,5 kHz 9".
I mainly search for coins.

Kindest Regards

I think in most soils, the 10.5" MF DD would be deepest for most coins, and offer the fastest ground coverage. Minelab has a website that offers a brief statement as to which coil(s) might be preferred for different uses. HH, George (MN)

For general coin hunting I would go with the DD 10.5.
