Hi all, Took the v3i out today with the 10dd coil on it and played with recovery delay settings and come up with a setting of around 65 to 70(closer to 70). This setting had very good target separation. I tried to also slow my swing speed down also. I then went to my test garden and tried several different filter settings over a buried coin but could not tell any difference in any of the filter settings that I used. All the different filter settings acted the same. They all had the same audio and the graph was the same on all settings Am I missing something or over looking something? any help would be appreciated.
