Fisher F75 large after market coils ??

[88junior]

I'm looking at adding a larger than stock 11" DD coil. I'm looking at the NEL Tornado or a 13" Ultimate. Have any of you used either or both of these coils? Let me know what your all experiences with either of those coils was. Thanks Morgan

Morgan----I have used the 13" Ultimate.----Of course it provided better coverage & I gained about 1" depth (in my ground) from the 11" stock coil..------I used the Tornado & the weight of it wears you down compared to the 13" Ultimate.------Del

Thanks for your reply Del. I'm leaning more towards the 13" Ultimate.

I also had the 13" Ultimate, as stated above it will get you about an 1" to 1-1/2" over the stock 11" coil. You will also get a little less target separation.

I traded mine for the 5x10 DD elliptical.

Good luck,

Ron

is good but heavy. (and lighter than that 15" Fisher)
Nel are lighter, but have had QC issues. (might be gone now--they are at 4th or 5th generation now)
Check out the Mars units.-have had very good results with them.
I have found most loops of similar size have depth & separation that are similar--but quietness can be another matter-and these are all DD coils too (noise is more prevailant in this design-in my experience.)
The bigger loops are Much Deeper, & i.d. deeper if you are using the all metal non motion mode---often deeper than you want to dig: recovery speed & target separation is NOT
a problem in this non motion mode, relative to the motion mode.
Most all the loops are compared on youtube.
If you have a problem identifying bottlecaps & steel washers, (with DD's) pm me--there is a way to identify them about 99% of the time w/ the F-75.
