Equinox Silver! And Some Pinpointing Issues With It


Recommended Posts

https://imgur.com/gallery/plMLq

 

So I’m frustrated. 

Im using the Minelab Equinox 800, had it for 3 weeks. Pulled a silver Rosie this morning in a 4 hour hunt.

My issue is when I find a target. I have a “clue” based on shovel symbols in depth, but trying to pin point, wiggle back method I’m always off. Sometimes by 4-6 inches laterally.  So I sweep, locate, pin point and dig plug... not in center, and most of the time way off.. inches off.

 

This is happens multiple times each hunt. This is time consuming and I can’t find a remedy. I’ve used 12 different machines in 1.5 years, and never had this problem. 

Anyone have target locator I’d or pin pointing issues?

Nope, can't say I have. In fact I would rate my Equinox better than most DD coil machines when it comes to pinpointing, whether by eyeballing the target or using the pinpoint button. I get the "ghosting" issue with the pinpoint function now and then but just move off to the side a little more and re engage and it works fine.

Let's see what others have to say. Congrats on the silver!

I don't know if this will help but when locating a target under the coil, once the line of the target has been established horizontally move the coil vertically (as you swing) to see where the target/tone falls off. Then move the coil back to horizontal sweet spot, move it vertically again (using the wiggle) in a much smaller fashion and you should be able to triangulate the target under the coil. 

Hope that helps.

Pinpoint is very fast and accurate on the Equinox.. One of the best I’ve used..  Coins on edge will throw of your pinpoint.. I almost always check from two directions.. Especially the high tones to make sure it’s not an iron false..

I have used all three of those methods (not at the same time) with reasonable success.  A few times, though, with the pinpointing function, it has seemed as though the target was a few inches to the left of where it should be. Probably just other things down there throwing it off as it was in a very trashy field. If I notice it again, may do some tests to see if there's a pattern...

yes, I posted my wiggle back pinpointing issue a couple of weeks ago.

I found mine to be about 1 to 1.5 inches off in Multi-frequency using the wiggle back method ( I rarely use the pinpoint button)

If I switch to a single frequency on the same target the wiggle back pinpointing  accuracy is spot on.

I am wondering if its the mineralised soil I have been hunting or if its just a multi-freq. thing I need to live with and adjust to.

DD coils have notoriously complex electromagnetic fields and any nearby objects or tilting of targets can pull apparent target centers “off center”.

Suggest folks read Dave J’s Text until they are satisfied that they understand at least 60% of it.

It took me more than 3 passes - and I’m not so sure about the part with the variables.

All those folks who fantasize that maybe someday they will design a metal detector - duh.

If this stuff was as easy as writing a program or app - we would have hundreds of detectors to choose from.   

Full marks to ML for creating the GPZ700 and now the Nox.

Perhaps a bit of patience is in order when it comes to new technology development by First Texas and others.

The easy stuff- and a lot of hard stuff - was done a long time ago.

      I've read several threads on the soon-to-be-fielded Deus 2 and how it will compare to the Equinox. There have been many good views on this topic so I thought I'd share mine. As you read this, keep in mind the views expressed here are worth just as much as you've paid for them. 😁

      1. Wireless vs Wired: I'm 99% a salt water beach hunter with my EQX 800 and the way I grid a beach, I often go from the damp sand to the wet sand and then into the surf (only about 1 foot deep due to concerns over water intrusion so I keep the control box dry). Given that, a Deus II for me would have to be constantly wired from coil to control box in order to work in the surf. For that reason, a totally wireless capability would not be that enticing since the wire from coil to box would be a permanent configuration.

      2. Waterproof: I owned a Deus and found it to be a solidly engineered machine so I'm not a skeptic where XP claims of being waterproof are concerned. Were I to make a wager, I'd bet on much better waterproof performance in the Deus II than was the original ML waterproof claim for the EQX. Being truly waterproof is important for me and not because I hunt deeper than 1 foot in salt water these days because I don't. Ours is an outdoor hobby so I think all detectors should be waterproof...at the very least, reliably weatherproof. How many times have you been caught in the rain or dropped your detector in a puddle of water? Even if you are a land hunter and never go near any water, replacing a damaged or inop machine due to moisture intrusion isn't a trivial thing.

      3. Build quality: The Deus I had was quality built, rugged and reliable. No coil ear issues, wobbly shafts or arm cuff breakage. In my view, it was a much more rugged detector than Minelab products in certain areas. XP doesn't seem to pinch pennies as did Minelab on simple things. Recall the original skimpy gaskets they put in the CTX 3030 that caused flooding of the battery box. The issue was solved when they came out with merely a little thicker gasket! Their use of cheap coil ears, arm cuffs and wobbly shafts on the EQX series is another example. For a few pennies more per unit, they would have saved untold thousands in warranty replacement costs in both the CTX and EQX series machines. Although they are among the very best where software technology is concerned, I never understood that "penny wise pound foolish" approach in their physical build design.

      4. Overall Performance: This is where the EQX was superior to my original Deus. The multi-frequency/multi IQ of the EQX vs the selectable single frequency of the Deus was an obvious choice in my salt water beach hunting environment. I eventually sold my Deus for that reason. Now, if XP has really overcome that limitation in the Deus II with their FMF feature, I'll be happily impressed.

      5. Final Thoughts: I'm with the others who will take a "wait and see" approach. But, given my past experience with XP engineering, I have no doubt the Deus II will be a very capable salt water beach detector. Will it generally outperform the Minelabs? TBD. Will it be found that XP pinched pennies on their build quality? I say no. It will be a well built unit. Will it be more comfortable to use than the Minelabs? Yes. Will it be more complex in its settings options than the Minelabs? Yes. Will it's overall performance justify the higher price tag compared to the current EQX? TBD but that will be determined solely by and in the eye of the beholder as the saying goes.

      Just a few thoughts from my foxhole...

      I'd like to increase my knowledge and skill in tuning my Nox 800 for specific conditions.
      Those of you who tune your machines off the factory defaults, please share what you have!  Not what your settings are, but how you arrive at those settings.
      For instance, is there a relationship between different settings, such, that a preferred order of operations is suggested for optimal results?  I noise cancel, then ground grab, then adjust sensitivity.  FE2, Recovery, Threshold, is there a best practice for the order in which they are set?
      How do you know when you should increase or decrease FE2 or Recovery?  What factors or indicators go into that decision?
      I've arrived at my current default beginning state, by trying to make things first "worse" in my test garden.  By adjusting each setting individually up and down though the full range of adjustment, noting whether signal got better or worse at each step, to get what I considered the best signal on a deep silver coin.  But doing so in a controlled situation with a known target like that is one thing, knowing how to read variable conditions and how to tune accordingly is quite another.
      How do you make your tuning decisions in the field?  What are the settings you most frequently find need adjusted to accommodate search conditions?
      - Dave

      Here are some improvements to the ergonomics of the minelab equinox 600/800 made with a 3D printer

      Just like the college sports transfer portal, I too have decided to change my mind.😁  I was set on buying the new NM Legend.  Instead I visited a local MD dealer today and had a chance to test drive the dealers Equinox 800. The Equinox 800 checked every box and then some.  It will get me where I want to be in metal detecting.  The dealer was pretty impressed on how I was able to navigate through the controllers menus and settings. It is on order and will be here next week.  Now for the "goodies" getting thrown in for free.  Both editions of Andy Sabisch's Handbooks on the Equinox 600/800, a Minelab Hat (I love hats), and any magazine, current or past editions that are in stock.  And there are a lot in stock.  Excited is an understatement.

      I had a very productive day hunting a city park in a nearby town. Took me 7 1/2 hours to round up all these keepers. The v nickel is the fifth one I've taken out of this park in the last 2 weeks. Ended up with a nickel trifecta to boot.  I think I'm going to get the 5x10 coil due to the amount of iron and debris in the places that are producing the coins. I did pretty good by going nice and slow and digging all iffy tones. I was very surprised to see the Canadian quarter come out, that's the second one I've found this year.

      I went back to a park that's been producing some good finds. Today was a very unusual nickel day. Ended up with 3 silver war nickels, a v nickel, an unidentified coin, 4 Wheaties and a religious medallion. I didn't really have a goal this year for silver coins but with today's finds that puts me at 112 for the year. Running park 1...2 tones..no disc...manual gb at 30..recovery speed 3..iron bias at F2-0.. tone break at 10...sens 23.  All war nickels hit at 15, the V hit 12-13, the unidentified coin(?) hits at 12.
