Need coil for my Impact

[dave_e]

Stock coil for my Impact died.
I've got the 7x4 football and a 7" concentric, but am wondering which coil to get to replace the stock 11x7.

Thinking about Nokta's newer 11" round DD, or a NEL Tornado, or similar.

Anyone have any experience with "larger" Impact coils?

I have the IM45 (45x39cm). It seems to be the biggest coil from Nokta.
So far I havent taken it on the field. From test seems to have 25% more depth than IM28 (28x18cm) which comes in the standard package.

I ended up buying a Simplex mainly to have the 11" coil and a waterproof detector.
I really like it, but I still prefer the Impact. It's so versatile.
I ended up ordering a Mars Discovery 13" coil for it.
Hopefully it'll sniff out some deep old silver when I throw it down into 5kHz and DEEP or 4 Tone mode.

I have the 11 inch coil and it works very well. I like it better than my stock one which still works. I have the Nel Tornado for my T2 and it works very well also.
