I actually have a Nel Big for my AT Pro. I completely agree that there is a substantial fall in depth to size as coils get larger. On average you gain at best .7" per inch difference so a coil that is 2" bigger you gain 1.4" on the difference. Masking is also another issue as the larget the foot print on the coil the higher the chance of being masked out. Large coils are also more suseptable to EMI interferance.

Not to go without saying that Nel Big worked very well at the beach on the towel lines and damp sand. In the wet it was surprisingly stable but only offered a couple inches in depth vs the stock DD.

People also have to consider weight. Probably the single biggest reason for me not to use the large coils very often.

11"-12" coils do well here in the NE though I do prefere the 8-10 wide coils for navigating moderate trash and still have that bit of depth edge over the competition. I have found less than 9" coils do well for woods hunting.

On my Kruzer the Superfly coil has nearly the same sensitivity as the stock 8" coil but also seems much less effected by EMI, depth gain about 1 1/2" and the same weight as the stock coil. When compared to the stock 11" coil for that machine I sent the 11" coil back and found it to be junk. I could have had a bad coil or it was just junk. Superfly on the Kruzer works very well in the salt. Will be using it for some fresh water soon. The stock dd has ribs on the coil making it more like a paddle in the water and very exhausting to swing. Superfly cuts through very nicely. Now that the weather is cooling down I can put the waders on without passing out in a pond smileys with diet Dr. Pepper float

General hunting the 10x12 on the Tejon serves me well, snagged a 12" deep class ring last fall then was able to find the owner who lost it 55 years ago. I don't use that coil in the woods but rather use the stock concentric. Would like to get a smaller concentric but think that Tesoro never made a smaller concentric for it. May try a Mars 6x9. Found the Mars coils to be incredibly stable but a little on the heavy side.
