Certain urban myths seem to never end.
I doubt many have as much experience running tracking GB because that is what I use 100% of the time, regardless of what machine I am using. I beach hunt and tracking definitely helps with changing black sand and the transition from the wet sand to water.
I have done lots of fringe depth testing and I can say that tracking does NOT affect depth. Tracking also will not cause you to lose a target. [that is nonsense] You will not be able to find one youtube vid to prove this either. Now SOME experienced gold hunters have reported that on micro targets like .01 gram it might be possible to have tracking issues. [might]
In summary: If you have a changing mineral environment or you doubt your skills to manual GB, it is wise to use tracking GB.

For the first 1000 hours I used tracking exclusively ..but for the last few yrs I use Manual, EXCEPT on salt beach. And very mild /clean soil.
No question at least in some soil conditions a deep IFFY signal will disappear if you investigate it for 20 or so seconds trying to clean the signal up .. I've proved that to myself on many occasions
