Settings for GPX using NF Evolution 12x8

Hi All and Merry Christmas to everyone.
Have had quite a bit of luck using a NF Sadie coil in the local Ballarat area.
Family came good for Christmas with a NF Evolution 12x8 Elliptical. (great deal as apparently NF send out a new Sadie as part of the deal and my old one is looking a bit tired)
Hoping some generous soul can advise re setting tweaks I may need to make for the 12x8. Seeking a little extra depth so that i can go back over areas where Sadie has worked well.
Present settings using Sadie are as follows.
Front: General, special, mono, fixed.
Back: Vol limit 12, GB Type general, Special fine, Tune whatever, Motion slow, RX Gain 12, Audio normal Audio tone 50, Stab 10, Signal 16 Tar vol 9, Response normal, Tracking medium.
Any advice greatly appreciated.
Regards, Wayne.

Thank you staples 61, much appreciated.

try deep on the front and audio quiet it the 12x8 is anything like the 12' round you should be able to run a rx of 13-15 easy with a stab of10-12,,, before I should say deep are you using a 5000???

Thanks Joe. Yes running a 5000. Used the tweaks listed above with success yesterday. Now I will try your tweaks as well.
Many thanks.
