Running up Disc on Makro Racer

Got one to play with and I deal with heavy mineralized soil that has extra iron infused into it so depth is limited anyway.
Using the small sniper coil I have reached down to the 3-4" area easily, maybe down to 5" on a few so far with pretty stable non jumping numbers...that is very unusual in this soil compared to my F70.
In a tot lot with chips and a little better black dirt I got down to 7-8" with that coil...all of this was in two tone with the disc at 84.
I had a bad big DD coil but Dilek sent a new one from Istanbul and I got it Friday so I will put that on and see what's up.
I assume I might get a bit deeper.

The F70 doesn't really lose depth on high disc and this is supposed to be similar in some respects but not sure about that high disc/decent depth thing so we will see.
I have had a drought going on around my area for over 2 months so not many places that I can dig down further than a couple of inches but I am getting some deeper signals with that sniper...let's see how deep the big coil goes whether I dig those signals or not.

I love how this thing can disc out so high, with it set at 84 I cut out all the stuff that comes in at the low 80's...which is way too much, but this makes it a cherry picking dream machine.
I have read info about using three tones to tell the difference on some of that low 80's stuff, saw a couple vids too, but I don't have all that down as of yet.

My big goal is to see how deep I can get in my rough soil with this thing.
Most can't get much past 5" with any reasonable ID's, I have made it to about 8" so far with my Fisher and the sniper coil, all my coils no matter what size, but I had to learn a new language to do it.
This one might act more normal deeper but we will see.

I generally don't run high disc.

I if my memory serves me correctly,,,my testing showed running high than normal,disc,,,negatively affected separation.

You might check for yourself.

Running high Disc doesn't seem to effect separation or depth but I wouldn't hunt really old sites this way.
This is perfect format for killing it in tot lots or just clad stabbing with small coil

Let us assume that a silver dime rings up as 84 on your racer (I have no idea what it rings up as - just throwing out numbers).

If you set you disc to 83, you are going to get a degree of discrimination on targets of 84 and may get a slightly broken signal. This degree of discrimination will continue in a decreasing fashion until around 88. This is the nature of filtering.

If you want to set really high discrimination, set it 5 below what your intended cut off is (in the example above, 79).
