Here is my air test on the Equinox 800 comparing the 11 inch stock coil to the 6” coil.
Did a factory reset and set sensitivity to 21, recovery speed to 6. Iron bias of 6.
Setup and methods: I set the coils on an all plastic child’s picnic table to eliminate any metal. Swept the table to determine there were no metal objects in the table.
Use a yard stick butted up against the base of the coil. My depth measurements were taken when the TID numbers for each metal object started going from a strong signal to an iffy signal. My hand sweep was done to replicate the normal sweep of a coil passing from left to right and back over the metal object.
I am a relic hunter mainly interested in Civil War items and only had three three ringers to test along with some silver coins. The results below are only for the .57 caliber. Not much difference in the slightly smaller calibers.
Below are just some preliminary tests and not the whole combinations of different items on all different hunting modes.

.57 caliber bullet at 5.5 inches rang up 16-19 in the park2 mode.
