In your opinion , do you think you gained any depth over a stock 11" coil ?

In general larger coils should go deeper. I can't state for a fact it is deeper because I never really measured or did an actual comparison.
I can say you will definitely cover more ground and found stuff deep and shallow which I probably would have missed with the smaller stock coil unless you are meticulous and overlap each sweep. I also feel with the larger coil I found more stuff at the periphery of the SEF coil (like a halo effect) then with the stock, so it seems to cover an even larger area.
I kepted it on 95% of the time unless the area was really trashy or couldn't get a good swing (woody area)

I use a 12x15 SEF on one of my excals and it gets more depth than the stock 10 inch. they are good coils.
