Remember thst since it is a 15x12" elliptical you are not going to get extensive depth over the 11" coil because the depth performance will be primarily driven by the 12" dimension (though as an elliptical it will get slightly more depth than a 12" round). The 15" dimension determines coil swing coverage more than depth.  HTH.

Excellent point, and maybe the reason for the delay in MineLab’s release of the large coil. A slight increase in performance may not justify the investment costs in most cases.

The Equinox fitted with the 15 x 12 inch elliptical Double-D coil will provide maximum depth using the 5kHz Frequency.   This frequency is ideal for hoard hunting in the UK and for relic hunting in USA.

Having some experience with the Nox 800, I do get better depth and more accurate TID numbers on large deep (Michigan) float copper targets at 5 KHz vs MultIQ.

I will need to confirm this in Field 1 mode as it is composed of more of the lower frequencies vs Park 1.  

I am referring to 10 inch diameter or larger targets down 20 inches or more. I suspect that multIQ really shines with smaller targets in trashier environments as in tailings piles. It doesn’t make me happy to say this because now I need to go back and re-detect at several locations. I can’t wait for the 15 coil to come out.
