It started in July of 2018. Took my new Nox to Mexico and even though I did testing at home before leaving it was disappointing to find that my Black Widows would not work, nor my Sun Ray pro golds. I did do some detecting but the wave noise on my beach made it difficult to really get into the machine.

Fast forward to January, armed with the correct connector to use my black widows I starting learning the Nox. First impression was, chatty, difficult to PP, and issues with moving water and black sand.  After the third time out I installed the update.  WHAT A FAIL! I had a new machine alright but it was working way worse. I consulted a few people with the machine and was told that the update may not always take.  I uninstalled and checked performance [seemed ok] Then put the up-date back on. What a difference! The machine seemed to perform better!

 Off to the report card! Saltwater Beach, Beach 2, GB auto.  

Dry Sand- [N/A] The dry sand is not worth my time where I hunt.

Wet sand grade: [A- ]: I found the machine to work the wet sand well [no water].  With light black sand I could work in 21-22 sensitivity. Very little false signals, worked recovery between 4-6, iron bias 2-3. Even though I did not make any great recoveries in this part of the beach by the end of the season I felt confident there was not much getting by me.

Wave Trough [moving water] grade: [ F] This is where I really like to hunt. To put it bluntly the Nox is a complete failure in moving salt water.   It is like the moving salt water makes the machine blind to detect and see targets.

 The beach is rough where I hunt. At any point water could be over waist deep, then 50’ or more of wet sand to the water.  If I were to stay in the wave zone completely I would have to significantly de-tune the machine do to the moving water causing the machine to false. When the water would drain out and I would locate a target the next wave is right there. When the wave would come through, repeated sweeping where the target was produced no sound at all. When the wave pulled back, re-sweeping showed the target was present. This happened over and over for 100’s of targets. Another drawback:  It was clear there was two different set-ups needed. One for wet sand, another for moving water. If I had the machine set for moving water that meant every time the wave swept out I was WAY under matched for wet sand only. Mainly I found I had to run around  17-18 sensitivity and 5-6 on recovery.  

Other issues comments.

EMI grade[ F]  I have over ½ mile of the beach where I need to back off the sensitivity by 1-2 regardless of other conditions or controls.

Pinpoint Mode grade [F]  The worst functioning I have ever used, Especially on a beach!

All metal mode grade [A]  Or as I nick named it the “truth mode” Almost every jumpy target I had would lock in somewhere, once put in all metal mode.

Recovery of targets grade [D] Well part of this grade is due to the pin-point mode, but make no mistake there are other issues, Even though I had the target out of the hole, many time the detector was still sounding off. Also it seems to be easy to bury targets or make them undetectable after missing them in the scooping process.

Thanks for listening. Please do not tell me how it works on land, in fresh water, or gold mode [I don’t hunt land] This is my honest review. Sure I have a few more things to learn, but I doubt my grades would change much.

Over-all grade C+

"GB Auto" - does that mean you were not using Tracking GB (which is recommended in moving salt water)?

Backing off on sensitivity 1 or 2 points out of 20 nets an EMI of F? Uh, OK.

Can you explain in a little more detail how you had to set up the machine differently in wet sand vs. surf?

Got me some waders last week and been out in the water three times now - so I wouldn't call me experienced... three different beaches - beach1 (!), Sens 22, GB manual at 0, recovery 6, iron bias 3 and the Nox runs quiet as a mouse..pretty impressive for a vlf machine in my book. No falsing due to waves, coil leaving / entering the water what so ever..

Friend of mine went out 3 times with his Nox and got 4 gold rings with nearly identical settings.

Maybe you should get a pi machine, if you mainly hunt in those difficult areas...

I was hunting directly under power lines yesterday evening...backed down on the sensitivity 4-5 ...did another noise cancel and the machine ran nice and smooth while still hitting deep coins. I'm sure you will have no trouble selling your machine on the used market.

For me the definition of "auto" [automatic] is the same as tracking GB.

Yes, having to back off for EMI of 1-2 points is an issue. Not only that, but everyone seems to be carrying a cell phone on the beach. I can not tell you the amount of times I can HEAR cell phones coming toward me, and of course much worse if they are standing next to me watching.
I also wonder even though one "knocks out" the audible EMI just how much it still effects detection. Even backing it off, I can still hear pulsing and or disturbance in the sound when a target is detected. That is 100% EMI caused. Grade [F]

To be set-up to just work the surf [complete water/wave action] I need to be in the 17-18  range for sensitivity as compared to 21-22. However in my location is never just an option to stay in the water only [it is too rough] So when the beach does drain for those precious seconds, I am sitting in a detection mode that is under powered for what I am swinging.  I found it was most likely better to remain in the best possible wet sand setting and wait for the water to drain to work the low trough. Working the beach in this fashion GREATLY reduces the amount of beach that can be covered in a given session.
The worst part of this equation is the loss of detection with moving water, as stated 100's of targets  could not be heard while water was moving past the coil. The water drains and the target re-appears. Grade [F]

Interesting that you were missing hundreds of targets at 17/18 sensitivity that you think would be picked up at 21/22 sensitivity.  I find other than absolutely tiny targets like a 0.0x gram gold nugget having that little difference in sensitivity won't really change much in the way the detector gets a target, in fact sometimes it improves it.  These 100's of targets would have to be right on the edge of detection, all of them!  Did you end up getting these hundreds of mystery targets?

You're worried about the invisible effects of EMI on the machine from peoples cell phones and so on near you, effects you're not actually getting but are wondering how much it's causing problems for the detector. This issue will be the same on every detector ever made. 

In MultiIQ the Equinox can get more EMI than single frequency detectors due to having the multiple frequencies which can let more EMI in, if that is causing you so much trouble you can drop back to a single frequency of your choice.

Your experiences on a beach are nothing like mine, I found quite the opposite, I guess some people just don't gel with certain detectors and as others have said, might be time for you to sell it and move on to another detector and see how much you like it.  I look forward to your review of your next detector at the beach.

You did not read fully, 100's of targets disappeared with the wave moving past and back down from my location on the beach. The targets were only able to be heard when moving salt water drained. The sensitivity setting did not matter for this issue.

You are completely incorrect. This is the first detector I have ever had EMI issues with.

What detectors have you had in the past with no EMI issues.  I need to get one of them as EMI is a problem for me in a lot of locations on every detector I own.

If I was as unhappy with my Equinox as you are with yours I would use a different detector. Life’s too short for me to bother with a detector that is not meshing well with me.

Hi Dave,

I was hoping you would engage in a problem-solving dialogue. As a new detectorist I have found the collective knowledge of this board helpful and its members forthcoming, courteous and understanding. One of the many reasons I like detecting is its a puzzle needing a solution. Perhaps your encounter in tough salt water conditions has an Equinox solution that if solved, could propel your detecting experiences to a higher level than you have attained thus far?

Just a thought.

      My new T2 arrived this week so I decided I'd take it out for a test run today, I haven't bothered detecting football fields before, it never really crossed my mind to do so especially small town football fields that barely ever get used.  I think the last time I even saw people on this thing was about a year ago and they were riding a horse 🙂
      I guess back in time it was probably a popular place and my results today show this.  This is going to be more of a picture story as the pictures tell 1000 words! 
      I started using the T2 with Mars Tiger coil and within two minutes of arriving I had my first coin, then another, then another..... it was nuts, coins everywhere and very little junk, I was finding nice old coins, possibly one of my oldest in a while too

      Silver 🙂

      1938 British Penny

      The T2 was getting good depth, easily hitting on coins with good ID's, another silver!

      1948 Penny -  Now NZ currency, not British like the older Pennies, we used some British currency until 1967. 
      Prior to 1933 United Kingdom currency was the official legal tender of New Zealand, although Australian coins and notes were also generally accepted.
      The first New Zealand penny was minted in 1940. The penny ran until 1965, when New Zealand stopped minting pre-decimal coins in preparation for decimilisation in 1967.

      I have no idea what this thing is

      This is the football field I was detecting, under the goal posts and along the end of the field had a good collection of coins,  I guess from all the diving with the ball and coins in the players pockets, I don't know much about football, probably the only NZ male who has no clue about the game 🙂

      My oldest find of the day, a British 1912 One Penny

      It was quite deep down but the T2 banged on it real hard with a solid ID.  At this point I decided I'd go home and gear up better as this place obviously has a lot of good old coins.  I was only using my T2 with Carrot and Lesche digging tool which was hard work with all the coins being so deep.    I wanted a bigger coil to cover more ground but there was no way I was going to strap on the 15" Teknetics coil to continue using the T2 as it weighs a tonne.  I opted for the Equinox with it's 15" coil  and almost straight away after turning it on, another coin

      1950 NZ One Penny.  I left the bit of dirt on the coil up the top it came out of, I love when you get the impression of the coin in the soil.

      Another silver, 1934 Shilling

      This is the hole it came from, I always recheck my holes and I'm glad I did, another target in the hole, then another... this was crazy

      3 Silvers in the hole so far, 1934 Shilling, 1934 Shilling and a 1946 Sixpence, I was sure this was it but I did another check and off to the side of the hole, ANOTHER SILVER

      Another 1934 Shilling, 4 silvers in one hole, incredible!   Someone had a bad day.

      1964 Sixpence... the coins just kept coming, all old ones.  No longer are they made of silver in 1964...

      Nice and deep though
      My first modern coin, a $2

      But look how deep it was, it was deeper than a lot of far older coins.... weird!

      Another two in one hole, just one cent coins from back when NZ had one cent coins.

      Another coin leaving a cool impression of itself in the soil, just a one cent I think

      It sure a lot of ground to cover, I'll be at this place for weeks... plenty more coins to find I'm sure.  Time to head back to the car, with my coil to the soil.

      Another for the road 🙂 Double sided impression on the soil with this one.  I couldn't possibly put up a photo of every coin find as there were just too many, all in about 3 hours detecting.

      The good stuff

      The bad stuff... not a bad ratio, good stuff far outweighed bad stuff, unusual for me.... I'll be back there tomorrow.... and the next day.... and the next day 🙂

      On the advice of others on this forum, I called Minelab today to inquire about the play I've had in the shaft on my Equinox since day one. When I called back in 2018, they wanted me to send the whole detector in to get looked at. This time they said they would send the three pieces my way, and I just need to send the originals back to them. Has that been your experience for those in the same situation?

      As said I like both the Sport and the Nox face . The great thing about them as you hunt you can really look at the face of each and know what you have notched out . What makes the Nox even better over the Sport is you can notch out one number at a time .
       Oh I know the Nox has so many fine qualities over the Sport it will never have but like the Nox it has a pretty face .
       I don’t know why but a pretty face always tugs at my heart strings and a detector is no different.

      I replaced the end plug on my Nox and thought others might like the idea. I don't know if anyone else has done this before but I replaced the plug with a bicycle handle bar plug. This was done purely for cosmetic purposes as the plastic end plug it had did its job just fine. These are the ones I went with https://www.amazon.com/PRO-Bicycle-Handlebar-Plugs-Black/dp/B00JATNUGS/ref=sr_1_4?keywords=pro+bar+end+plugs&qid=1567359452&s=gateway&sr=8-4 . Just a simple plastic compression plug with a nice aluminum cap. They came with black coated steel screws though so I'll replace them with stainless ones when I get the chance.
      There are other brands, styles, and colors of these types of plugs but just make sure to get the right dimensions to fit inside the shaft and not interfere with the arm cuff screw. Many of the listings don't specify the dimensions of the plug. The ones I got have an OD of 23.5mm (the smallest I could find) and my shaft OD is 22.2mm so there's a tiny bit of overhang but my arm cuff is all the way to the rear so it didn't bother me. The only thing I had to do to make them fit was trim about 1/2 in. off the end of the screw to keep it from hitting the arm cuff inside the shaft and I also used some blue loctite to ensure the screw doesn't back out.

      I have a very early Equinox, after buying the 15x12" coil mine rapidly developed the dreaded shaft wobble, the bottom cam lock just wouldn't tighten enough to stop the shaft wobbling and swinging the big coil really made it obvious, then going back to the little 6" and the problem went away.  I contacted Minelab about it and they were great and sent me out a new shaft pronto which was nice. 

      They used international express from OZ so it arrived within a few days.
      I then started paying attention to the aftermarket shafts and saw a few people were enjoying using various carbon fiber shafts so I thought i'd try one out.  I went with a Detect-ED shaft, the Classic 3k Twill
      It arrived today, the local courier was kind and delivered it on a Saturday for me seeing I know her, saved me waiting for Monday when it would normally arrive.
      I also purchased some of the Coil saver washers he's selling.
      The washers are interesting, two sizes that you mix and match to get your coil so you don't need to over tighten the bolt to help keep the coil in place nicely.  They seem to do as described, one red and one black on each side of my shaft seemed to do the trick, I can have my bolt just slightly turned and my coil is nice and tight but still moves when I want it to with ease like when I put my detector down.

      4 Red's (thicker) and 4 blacks to mix and match with.
      The shaft is lighter, it's more noticeable with the big coil as anything to take a bit of weight off when swinging that thing is nice

      You'll see I have a ferrite choke on my coil cable, not sure if it does anything but I've got plenty of them so why not 🙂
      It took about 5 minutes to put the Nox on the shaft and it came with the tool required to remove the control pod off the old shaft.
      The clip that lets you shrink/expand the shaft is nice quality, it's quick and easy to reduce the size of my Nox for transport now.
      So far I really like it, I can't see any negatives to the upgrade and my Nox now feels much higher quality, I really felt the stock shaft made the Nox feel cheap. I think it's far too good of a detector to run off that basic cheap junky shaft.
      I now just want to source a better quality arm cuff.
