Cool answer bro..that's what experience and professionalism means..I respect your answer. Prunt. You are cool bro. I am waiting for the money and will buy it soon. MINELAB EQUINOX 900 is a really cool machine. which works for me. Listen, if I buy a coil of 6 sizes, what size should I buy for the second coil? I know that 6 size coils work very well on gold. And what size coils are included in the MINELAB EQUINOX 900 set?? It turns out 6 coils, should I buy an additional one? Can't I make it so that the set includes 6 size coils?? And secondly, what size coil will I need to look for in fields, forests and on the ground???
