Just posted this on FB group, awaiting a reply. I am a newbie and have seen several XP Deus VDI charts. These charts all have four columns for four different frequencies. Isn't there a setting called ID Norm where once enabled, all the same specific targets will have the same VDI regardless of frequency? If so, why would anyone not want this feature enabled so you would only have to learn one set of numbers? Also I realize it is best to learn to dig targets by their sound and not necessarily by VDI and yes I am currently trying to learn that skill. Thanks!
