Fe BAR? Omega and T2 right?

[bubbadirect]

I just finished sending sekypaleo and tmanly messages, but forgot to ask them about the Fe Bar on the right hand side of the 8000. What experiences have you found with these readings?

I have found that the Fe bar is usually around 1 when it is a coin, and 2 when it is a screw cap or other forms of IRON. Do you concur? If so, what experiences do you fellow folks have watching (if at all) the Fe Bar?

Happy hunting,

I've noticed a similar outcome as you have, however, I've only got a few hours on the machine so I can't say it works, conclusively.

In your Omega Owner's manual, page 16, it explains that the FE[sub]3[/sub]O[sub]4[/sub] Bargraph simply indicates the amount of ground mineralization, and while it is sensitive to coil motion it is most accurate when bobbing or pumping the coil over raw ground w/o metal or off mineral bodies. It states the presences of "hot rocks" or "metal" will cause the reading to be inaccurate.

Yes, it will show a reading when swept over a metal target, but that's really an error reading. perhaps interesting to tinker with if you're bored, but I prefer to use the tools for the task they were designed for and go find stuff!

Monte, I agree with your non function statement. I too spent the first 10 hours or so fussing over why I was not seeing any reading on the graph. Now, I never even look at the graph. About every three or four hours I will stop and pump the coil to see if it still works and it does still work.

is most accurate when pumping the coil. I will occasionally glance at the Fe[sub]3[/sub]O[sub]4[/sub] bar-graph if the 'look' of the ground seems to change, just as I might glance at the Ground Error read-out from time-to-time to make sure I keep the Omega 8000 set with the best GC possible. The same goes for the T2 or other models as I prefer to stay "on top" of the ground adjustment for peak performance.

Since I hunt in All Metal or with the Discriminate setting at '1' most of the time, I will hear any targets, including ferrous junk, that might be present so I am aware if a ferrous reading is influenced by a metal target. The read-out will reflect some ground mineral changes during the search when sweeping the coil, then a quick pause to bob the coil a couple of times provides a more accurate reading.

The soil around where I hunt is low mineralization so normally the Fe bargraph doesn't show anything. However I have noticed that when I go over a ferrous target it will jump up. So I sometimes use it as an additional reference to determine if the target is ferrous or non-ferrous. This is most useful when you get a target in the low to mid 90's that might be a big silver coin, or more often a piece of iron wrapping around from the low VDI to the high VDI numbers. It can also be useful when you get an iffy target that is jumping around a lot. I have dug several targets to confirm that it can give you some additional info in these situations.

I sold my T2 when the prices went crazy but have an F75 now and it works the same way, though the target confidence meter seems to perform a lot of the same function but works with non-ferrous targets better.

anyway I regard it as a secondary piece of info that goes into deciding whether to dig or not.

As Steve stated above i also have mild soil.My Fe bar barley shows up but on
a jumpy ID if the Fe bar spikes when pumping it over a target its deep iron.
I almost never dig iron unless i want to. At old sites and such looking for masked
targets in the iron.

My ground is almost always .3 but it really doesn't help me to know it. It is what it is.

and the fact I can't locate my manual at the moment, I seem to remember reading something about the FE bar graph being a separate circuit to the ground balancing circuitry. When reading about it, it had me wondering if it was similar to what you find to the ferrous readout that you get on the Explorer series of detectors? Obviously not as refined as that, but that's just the way it struck me. Yeah I know it's there to measure the magnetic level of the ground, it just struck me that it could measure the iron level of targets as well, in a basic sort of way.
