Need advice/want to buy small coil for F70

I am looking for a small coil for the new to me F70....I mostly park or yard hunt. I see the fisher 5" concentric and a 6.5" are available, and probably others....not sure what the F75/F70 users on here found worked the best.
If you have one you can part with, I am interested.
Thank you....

PS: Hi to Tom D. Miss my CZ3D you tuned....I shouldn't have sold it....

The round 5" coil is a DD configuration. I used it regularly on my F75, I found it very capable. Parkland is one place I have seldom used it, though.

It's coming with the 10" elliptical concentric coil that I consider small, that works very well.

For a smaller coil, Nel makes a coil called the Snake coil, that is 3.5 x 6.5 dd coil.

techman: Welcome back!
I have a F70 coil that is phenomenal in high-trash areas. It measures (nearly exactly) 6.5" x 3.5"........and is elliptical. If you want it....... I can ship it for $60.......shipping included.,.,.,.,., as long as you are ConUS.

Yes, perfect....I will PM you....
