Some nice features on the 8500:
NOTCH VOLUME – Adjustable Volume Offset by Target Category. Each target category can have its volume adjusted independently. This advanced setting affects the Master Volume setting and functions only in DISCRIMINATION Mode.
I really like the Deep mode. I'd equate the "Fast Filter" the the FA mode on the DST enabled T2 & F75 with the other modes being a permutation of a Boost Mode.
DEEP
This allows 4 settings with varying filters that may increase depth under certain
conditions.
D0
.Fast filter. Best for target separation and searching in heavy trash. It is
the least sensitive of the Deep settings.
D1
.Regular filter. Best for general conditions.
D2
.Deep filter plus 60 Hz notch. This is a slower return setting that will
eliminate some EMI. The noise floor will be increased. This mode is best
used in cleaner soils and Sensitivity must be adjusted for proper use.
D3
.Deep filter plus 50 Hz notch. Same as D2, but with a 50 Hz noise filter.
Multiple Target Category System.
This feature is available only in Discrimination Mode. For each target, the Omega 8500 calculates four
independent numerical Target-ID’s on each pass of the coil; one primary
and three secondary. Each one of the Target-ID’s will correlate to a target
category on the LCD. There will be one solid primary category lighting up
and up to three additional secondary target categories. All are different
readings of the same target, with the primary category being the one with
most reliable signal. If the Target-ID’s vary, they will show up as multiple
illuminated categories, and this could indicate the detector is picking up
noise, a faint/weak signal or that the target is irregularly shaped.
I wish they included the 11" DD vs the 10" concentric coil, the 11" DD was a great on my Omega for sniffing silver out of demo sites and iron trash. I never did get great depth with my old Omega (my F75 LTD blew it out of the water), hopefully the 8500 is more sparky and the "Deep" mode really is truely deep
