The main reason for ground balancing in AT mode...you want to ground balance over clean turf (no target beneath the coil). Scanning in AT mode prior to GB will assist in finding target free dirt for accurate GB.
You can quickly scan the spot of ground before adjusting the Ground Balance by simply using the Pinpoint function. The only time I opt to do a Ground Grab or manually Ground Balance in the Auto-Tune All Metal mode with the Omega is when I plan to search in that mode. That way I use the combined function Sensitivity control to first set a 'proper' Threshold audio then I can Ground Balance.
The Omega, like the T2, allows the operator to simply use pinpoint to check the ground, if they want to, then use the Ground Grab (Fast grab on the T2) to quickly do an automated Ground Balance while in the Discriminate mode. It's just the same quick adjustment you can to with the automated GB of the White's M6 and MXT's while in a Discriminate mode.
I bought my Omega 20 months ago and I have never had a problem adjusting the Ground Grab or manual GB setting while in the Discriminate mode. You have the benefits of:
1.. using Pinpoint to help verify a functional setting
2.. glancing at the Ground Error display to see if your GB is too positive or too negative

What are the reasons for using one mode over the other? Do you turn up the disc, or do you notch, and leave the disc at 1.
Sorry, Canes. Did not mean to hijack your post. I am trying to learn about the Omega also.
With the Teknetics Gamma you have three 'mode' settings to choose from: Discrimination, All Metal and Ground Balance. With that mode you are can't adjust the Ground Balance unless yo go to that menu selection.
With the G2 you have to select the All Metal mode to adjust the Ground balance.
With the Teknetics T2 you can be in either the All Metal or Discriminate mode and use the trigger toggle to make a quick Fast Grab (different name for Ground Grab) while bobbing the coil 3-5 times .. OR .. select the All Metal mode and menu select the Manual GB option to adjust it manually.
With the Omega you can use the Ground Grab touchpad and do a quick automated Ground Balance .. OR .. you can use the Up/Down touchpads to Manually Ground Balance while in
either the AutoTune All Metal mode OR the Discriminate mode.
I never use the d3 three tone audio ID. Instead, I use the d4 four Tone ID when hunting primarily for fast change in typical coin-loss sites such as wood-chip or sand-filled playgrounds, around modern use picnic sites, and maybe a few casual hunting locations. Most of the time I prefer to use the d2 Two Tone ID function and I always have my Discrimination set at the minimum setting of '1'. That setting is only going to reject certain iron objects but most iron, if in the area, will produce the low base-like audio tone, and non-ferrous targets will produce the higher-tone.
Sometimes I do select the d1 single-tone ID depending upon what I might be after and the make-up of the site.
The ONLY time I really favor the All Metal mode with the Omega is when I do want true all metal detection. The Gamma and Omega use a '1' as their lowest Discriminate mode setting and the G2 uses a '0' to refer to the lowest setting, but none of these models actually adjust down to a true, all metal accept/zero rejection level like the White's M6 and MXT models. Only the Teknetics T2 adjusts down to truly accept all metal signals while only ignoring the ground signal in the Disc. mode, and that's with a setting of '0'.
So, with the Omega set at '0' Disc., Tone ID at 2 tones, and all the Sensitivity I can use at a site, I simply do a quick bobbing Ground Grab and start hunting in 5-10 seconds after I turn the detector on. I like simplicity and performance, and the omega fits those requirement just fine.
