sef
I purchased the sef 10x12 for my ex2 and my mxt.I was really expecting something special after reading all the forums.
on my whites mxt the coil read a silver dollar as a quarter at 8 inches.The stock coil read it as a silver dollar.At 10 inches both coils had a hard time with the dollar but I have to give the edge to the stock coil.
On my ex2 I have a Platypus 8" x 12" coil.I really dont know why I got the sef for my ex2 as the platypus is a great coil.I'm kinda new to metal detecting and wanted the latest and greates.LOL
Both coils piched up the
dollar at 10 inches,however the platypus coil was more responsive and gave off a lower sound.
In my opinion the sef coils did not preform as advertised.They may preform better on on different metals like iron or clad coins.I want to find targets like real silver.The $1 I used was a morgan out of my collection.
I'm now looking at a large coil for my whites and would stick with a whites coil from what I been reading.I'm going to get a super 12 or a 10d2.
As for my ex2 I would have to say that the platypus works as advertised.I want to try the new coil from minelabs the 11 dd coil.My guess is that I have one of the top coils already.I myself will stick to coils made by whites,minelabs,and coiltech.I have heard good things about jimmy sierra also but have not tried any of those coils.I hope this helps
