I spent about 5 1/2 hours digging in the dry beach area of the lake. My goal was to dig as much trash as possible and it worked out great I was able to nab a few keepers among the junk, silver toe ring, 2 silver earrings and a silver chain with the pendant. Also dug the usual clad and junk jewelry as well.
Ran the Nox 600, my settings were:
I dug everything from-2 up

Received my EQ 600 back last week from repair service, they did not indicate what the problem was but, stated they tried my coil and their coil to test and determined the problem was in the Pod. (note i was getting a CD code then it would turn off, then i got a CD and ER11 code and would turn off)They stated it has been replaced and tested and submerged for water ingress test, passing all test.
Due to work, I have been unable to try it out, they just opened up our county beaches Tuesday so maybe when I'm off Monday or Tuesday I can give it a go! I also found a good deal on a 15" coil brand new, will test it as well.
I see they have done the upgrade with the 4khz frequency. That started me to think, if Minelab can upgrade my 600 pod to include 4khz. then doesn't it stand to reason they would be able to upgrade my 600 to include either the 20 khz or 40 khz or both frequencies making it a 800? Both are using the same coils, battery, same housing etc. just programing I would think. When I spoke to them on exchanging my 600 that was defective to a 800 I was informed they do not have a exchange program even if you wanted to pay extra for it. Just thinking if its that easy to install another frequency why isn't the 20khz included if most of us are searching for gold rings at least I am. Then the silver hunters would be happy, ring hunters happy as well..oh forgot then you would not buy a 800. silly me!
If I can get out and run a test I will let you know how it goes.
Happy hunting everyone enjoy your weekend!

Jeff and I had a couple PM messages back and forth about Iron Bias, and what it does. Jeff made mention he thought it took items with mixed ferrous and non-ferrous responses and reduced or eliminated the non-ferrous response, leaving only the ferrous response.
I usually set Iron Bias to 0 unless I forget and leave it at some default setting. I hunt full tones and between high 39 spikes and audio "tells" while in full tones I generally do not have much issue with ferrous tricking me, and so it has not been anything I have investigated much. The bottom line is I was feeling vague on exactly how this control acts in practice.
As we all know bottle caps with the normal FE settings had a habit of reading in the mid-teens near 13. I have also run into issues with large flakes of decomposed steel cans in old mining camps that read in the teens. I'm not worried too much about bottle caps, but in some old camps that rotted tin can debris can really mess an area up.
Minelab introduced the new FE2 setting that allows for more range on the control. Jeff's message made me wonder - is Iron Bias reducing the non-ferrous false signals, or increasing the ferrous signal? This short video shows the problems and the solution, and answers this question.
I start with a piece of tin steel that gives a non-ferrous reading around 15 in normal FE mode, and show that from FE0 to FE9 the target gives a clean mid-tone with no ferrous report of consequence. The old FE setting was ineffective on this stuff.
Then I go to FE2 and show that increasing the setting rapidly shifts from a non-ferrous reading to a ferrous reading. At 0 it's clean non-ferrous. Just going up to 2 makes it a mixed ferrous and nonferrous reading, at 3 it's mostly ferrous with some high tone mixed in, and at higher settings it is a solid ferrous reading of -7.
To me it looks simple. The control is variable, and a particular item can be adjusted to read solid non-ferrous, or to give mixed tones, or to read solid ferrous. It is not a matter of just decreasing the false signals. More like converting what were non-ferrous signals to ferrous signals in a continuous range.
This all goes back to the ferrous versus non-ferrous range having a full overlap, and much like how you can use the tone break to decide what items near target id 0 read ferrous and which do not, the Iron Bias offers a secondary control that does the same with these problematic items.
The part I do not show? There are good items that will do the same, and I need to try and find one. In theory there is a good item that will give a false ferrous if this setting is too high. Otherwise we would not need the control. Just set it to max and forget. So the real question here that I think remains is not about the ferrous. The control will clearly help with making ferrous items read ferrous. But what about the reverse? What non-ferrous items will be revealed by leaving this control at a low setting? I take it as a matter of faith these items exist and so I leave the control low at or near zero. But how common are they? Am I suffering needlessly? What are the risks of setting the control too high? Minimal risk, or high risk? The best way to find out may be to simply go detect, but take the time to double check items at the full FE2 setting of 9 to see how many might read ferrous when they are not.
Be patient - it might take a minute for the video to start once you hit go.

I even bought the universal charger with 4 USB ports from Minelab and NEVER used anything but this to charge the machine.
I have used it three times, I plugged it in the first night and I though it charged it fine. I had not been paying attention and today the fourth time I took it out it flashed BF.
Left charging all day and green light even stays on indicating that it is fully charged but when I turn it on its flashing the battery meaning its less than 5% charged.
very frustrating, going to try another charger that has greater than 2 amps.
Thanks for any comments / feedback
