Target ID Chart Differences Between Equinox 600/800 And Equinox 700/900/manticore

Give me an expanded meter anytime.   Thats one major thing i did not like about the eq 800.  I had a Rutus alter 71 a few years back, and I found the most jewelry with that machine, as it had 120 segments.  I would go into a ballfield bleacher area, and the rings would lock on with a solid number, where as the aluminum crap would usually bounce a bit. The only aluminum that locked in was the tab when broken away from the ring. 

The new Rutus Versa has 120 points also, divided up a little differently than previous models. It and my Whites MXT 180 point scale do a good job boxing in common Al trash.   How a detector processes & normalizes the SMF signal is really the secret sauce on TID.  The Nokta Legend only has 60 points, but has the most solid TID lock & accuracy out of all my detectors.

The only machine I have experience on is the D2 with 100 scale. I HATE it. Throws gold and pull tabs all over the place. My Equinox makes calling tabs 100% easier. Almost impossible to skip any tabs with the D2.

Dave,

So you're saying rings never ID as Tabs on the Equinox?  That is, you can confidently skip whatever ID is associated with a tab on the Nox simply because its repeatable?

No, Rings of course can ID at 14.

Yes, 95% of my tabs come in at 14. I get a few 13's and 12's. 

Like today, my conditions did not warrant skipping tabs. I dug 1 a solid 14. However, when the wave conditions are right I could have 100 14's banging my ears. On those days, I skip 14's.

Now opposed to the D2 

Inconsistent pull-tab numbers that range from 48-64. With almost no back-to-back repeat numbers. Drives me insane and makes it impossible to have ANY comfort zone on skipping tabs. ?

How did the conditions differ?

[midalake]

When the wave conditions are right, soft waves and sand can bring lighter targets in.  I could have 100 14's banging my ears. On those days, I skip 14's.

Thanks for the inspiration @BigSkyGuy. Here is a very similar chart to yours, but done in Excel, for the 800 vs the 900.  There were 40 items tested with both using the 6" coil. The settings are below. The 900 had lower than max sensitivity for stability purposes. 

(Sorry if the pic is huge. I couldn't adjust it.)

 

A couple of notes:

• The one iron item was a square nail.
• The stack at 1 on the 800 is foil, a 0.054 g flake, a 0.65 g nugget with host rock, and a 1/2 vile of dust.
  • A chunk of graphite was 1 on both.
• The stacking of data points for the 800 may represent more perceived stability, but versus the larger scale could just give that impression.

To test the last bullet, here is a chart of the 900 TID divided by the 800 TID vs the 800 TID data point.  It's not surprising on the low end (1 or 2) the multiple gets out of whack as a 4 on 900 would obviously 4X a 1 on the 800, but that extreme doesn't carry through.  The chart does provide another way to look at and, I think, confirm the attempt at a higher resolution mid range.

Looks very similar to my plot Lync. Good to have it confirmed using a different set of items and different detectors. Have you tried plotting the line to your results using the equation that I provided?

[Lynk]

Good call....

It did work quite well, I think.  Not surprisingly the two things that cause issues are iron (negative numbers) and very low positive numbers.  A couple gold nuggets were off by 5 or 6.

 

(Not sure why these don't paste smaller!)

The square nail was by far the largest issue. Ex that the standard deviations come in a far amount.
