Interested to know if there is much difference between these two coils, who has used both?
 
Exactly as you'd expect, 12x8" is slightly more sensitive, 14x9" is slightly deeper. On a 5000 with Fine Gold they are very close in performance depending on Rx Gain settings. On the 4500 with Enhance, the extra sensitivity of the 12x8" is a little more noticeable.
 
I hear there is a whole new lineup of flatwire coils coming from NF for gpx/gp/sd as well as the gpz new coils. Will be interesting to see if any advancements other than more emi resistance.
 
Smaller coils for shallow gold and bigger coils for deeper gold.
I still say you're only going to here what your detector is putting out. :cool:
