JW,

  If I'm understanding this, running in Auto, automatically adjusts ferrite for you, no use for ferrite ring. Only in semi, or manual.

The Ferrite is needed to accurately calibrate the detector, the ground holds varying degrees of Ferrite like signals called X. In Auto mode the detector will slowly measure any X component in the ground but can be adversely affected by Salt and Saturation signals. If there is no Ferrite available then the detector can be used in Auto mode and hopefully the ground conditions will allow for a reasonable X measurement.

When Quick-Trak is triggered the X balance and G balance track really quickly then throttle back to their respective speeds, in the case of Auto mode the X balance is really slow with an active G balance when Quick-Trak is released. In Semi Auto mode the X balance is FIXED once the Quick-Trak button is released.

If you do not have a Ferrite then with Quick-Trak engaged used the "Walk and Detect" method shown in the Minelab YouTube tutorials. Ideally it is better to use the Ferrite at all times using Quick-Trak in Auto, Semi Auto or Manual mode. Using the Ferrite is far more accurate than solely relying on there being enough X signal in the ground.

Hope this helps

Thanks all, and JP....

  Hey JP I had a question. DO you gain most of your knowledge on these machines with trial and error in the field yourself, or do you actually get to pick Bruce Candys brain ???

Thanks,
Dave

I bet it's both Dave...

Dolan Dave, good question mate, I'd like an answer to that one as well. Why was the ferrite ring produced as an afterthought?

Reg I think you must have a large callus on your left hand index finger .......

You missed the R next to the T in Austtalia above. ?

Thanks Geof. That better? Would still like to know why the ring came on the scene some time after the 7000 was introduced, and then treated like it was always a part of the plan. Was this a 'patch up' tactic to rectify some initial shortcoming?

Yeah is interesting but the ferrite made no diff in my ground, buh.....regardless as long as ML keep coming out with MDs that put the weight in my pocket as they have for........ crikey tis getting onto 30 years................tis great to have an Oz Co. that is a world leader, their MDs have enriched my life, may they keep progressing.
