Just a very quick summary. With 2.77 update


Air Testing
Stable in doors at full Gain. Very stable at 6 bars. Too stable at 5 bars.

Id's not to jumpy and most lock on

8.5" has about 4" depth over the 9.5x5

Bench testing for my type of hunting, the 8.5 coil will be my go-to coil.

High trash areas where you don't need depth the 9.5x5 maybe a better option.

Both coils will be a hit, depending upon your needs.
