Been fishing for about 2 years and I must say the break from the detecting has done me a world of good.

Dug up the CTX from the attick, gave it a dusting off. And while I was figuring out how to ride a bike again.

All the mist was blown out of my head and we got down to the nitty gritty.

Bought myself a new GPS unit to log waypoints. I’m not wandering around like a drunk anymore, this time around I’m gridding.

As a beach hunter, tried the dirt and parcs. But my heart belongs to the beach, pretty obvious when you like fishing and fresh air.

So the obvious choice for logging finds and hotspots is Navionics Boating App, weather and tides integrated.

Several outings with the CTX and a scarred coil protector has opened my eyes and forced me out of my comfort zone. Last time around I tried to use the CTX like an Excalibur. This time I listened and let it talk to me. Learned the CTX language a bit.

A few outings later I the happy owner of another ring and my most prised CTX targets: a stainless screw of 0,8 gr found on the wet slope that was just a slight blip in the landscape. And a piece of stainless wire 4 cm in length weighing in at 0,3 gr at the wash.

People say the Equinox 800 can find gold chains, but surely if the CTX can detect such small stainless items. It has a chance at bringing home the goods. GB manual, Sens running borderline, All Metal and trying to wear out the coil cover.

I’ve watched countless Equinox 800 vids, seems like no other detector is made anymore 🙂 But at the beach people aren’t finding gold chains by the dozen. Just the usual rings and coins. Are they not using it to it’s full potential??

Anyhow still happy with my CTX, but that gold chain I found with my Equinox 800 MKI is still bugging me to get another. Maybe the Equinox 800 V3 MKIII will be more to my liking. Or have I learned a valuable lesson,... LISTEN and DIG.

If you tune out saltwater you eliminate the small gold signal along with it. Any detector can be pushed to the edge of just barely detecting the saltwater, and no more. Otherwise the detector would sound constantly. A machine that is experiencing just the slightest bit of salt water falsing is right on the edge, and can go no father.

We have had machines that can pick up thin gold chains since the 1990s at least. Any decent VLF nugget hunter would do the trick. Gold Bug 2 for instance. Except they do not work on wet salt sand. They are TOO SENSITIVE!

The whole pick up tiny earrings and thin chains in saltwater is one of the most overbaked yet least understood areas of detecting. We hit the wall on what the tech can do there ages ago. There are a lot of tiny low conductors that will be eliminated along with the salt signal because to the metal detector it is the same signal, the same thing. All the detector sees is a very low conductive signal - period. We can set the machine to find those, but now it won't work in saltwater. Or you can tune out the low conductive salt signal, but now you miss all those tiny gold and platinum targets also.

Get the Equinox, and using my nugget settings you will be able to find exceptionally small gold. But those settings will not work in saltwater.

Or you can use the Beach Modes to deal with the salt, but now you can't hit the tiny gold. The capability is there, but it is one or the other, this or that. You can't do both at once, it is the nature of the technology.

The minute Equinox came out and people started speculating on gold chains, etc. I knew it was the same old same old. People do not understand the physics, and so they think a new detector will somehow change things, but it can't happen. Not as long as conductivity/eddy current retention is the tool we use to make our determinations.

Long story short, if micro gold is the desire, I would use any detector that can tune across the salt transition zone - in other words that can balance to salt and beyond. The machine needs to be able to pick up saltwater. Then slowly detune it until there is just the barest indications of salt false signals beginning to occur. You are now on the edge, and you can go no farther. If a machine cannot be made to pick up saltwater, then it is tuned to be well below that threshold. Salt content varies around the world, and many saltwater machines are set up to ignore the worst. But if you get into lower salinity water, now you have poor sensitivity to tiny gold, or at least poorer than is possible.

This is why numerous detectors, especially many single frequency machines, have a "SALT" setting. The MXT for example. If not around saltwater, leave Salt Mode off. If you hit the beach, use the Salt Mode. Engaging it eliminates the salt signal, and the thin chains and tiny earrings, etc.

For ages I needed two detectors. A beach detector, and a hot tiny nugget detector. Nobody made a machine that could do both. Equinox is special because I can hunt Hawaii one week, and hunt tiny gold nuggets another week. It can do both very well - but not both at the same time.

The chart below shows where salt signal occurs relative to other targets. Just barely into the positive range. This is also where small low conductors read - foil, thin chains, post earrings, tiny gold nuggets. Keep in mind platinum reads lower than gold.

Thx for the definitive explication!

Back when the CTX came out people we’re complaining it was unstable in the wash.

Minelab added the Seawater setting and you could instantly up your Sens. I found that a bit contrary. Make it numb and then try to get it sparky again.

I found the small 1,8 gr gold chain with the Equinox 800 MKI at the high tide line during ebb. As we get tides of up to 5 meters in height salt influence has been mitigated somewhat. Add a little rain and neap tides into the mix and the high tide line becomes VLF territory. But people don’t like small foil. Most expensive foil I’ve ever dug 🙂

SDC in the wash is just the same as the CTX. It needs time to tune in and out as the seawater runs over the coil. But on the other hand I was digging an awfull lot of stainless fish hooks down below on the wet slope, rings and coins on edge too.

Sold it because the coil is solid and tends to stick to the wet sand. A major pain. Held on to it far several years and then coiltek decides it want’s to make solid coils as well. Oh well time to move on.

With all this talk about the IQ and the unavailability here in Europe I stumbled upon VALLON. Had a nice chat with their representative and they are testing 1 mm multi stranded stainless wire in a salty environment as per my inquiry. They have a nice selection of open coils. A 1 mm stainless wire and not a gold chain because I need to hit robotic mower wires 5 cm deep along the coastline. People want quiet mowers in summer during tourist season. But hey why not give it a go on the beach as well.

Anyway, so there it is. Beach performance of detectors is physics. Just need to get one you can drive to the edge.

Hi scoopjohnb, I own two VALLONS and one AQ. They are both deep and sensitive. Gold chains I’m not so sure though. My VALLON here in the US has had a  software modification by our US representative and I also have two 12” coils as well as the stock oval coil. Eric Foster wound me a special 12” coil using a TDI shell and a friend in Australia gave me the VALLON 12” coil. They both have the same performance so I am partial to Eric’s coil. At $800+ for the VALLON 12” few if any here in the US own one. If you swing the VALLON for a week or two, it will make the CTX fell like it’s the Equinox Lol. It’s a beast. All and all, the Fisher AQ limited is the one to beat. It is lighter than the CTX by roughly a pound, ( I use an after market battery that is 7 oz. lighter than the stock) and several pounds lighter than the VALLON. I think you will have no trouble detecting the wire at the depth you mention with the VALLON should the soil compensation be set properly. Good luck and let us know.

I will indeed keep you guys informed. Haven’t the faintest idea what the Vallon could be.

Never seen anyone on the beach with a PI over here. Excals, sovereigns and noxes RULE 🙂

That is probably a good deal.

The only number that the sales representative quoted me was something like 2400 USD. 

I’ll try and get his attention again and see where they are at.

none on ebay 🙂

You must have missed this one.  Price is low enough you could even afford the USA --> NZ shipping.  :biggrin:  And it's lightweight!

      I have a question regarding how the Equinox throttles back sensitivity when it encounters black sand.
      If I am running at 17 sensitivity on a salt water beach and detect over black sand; the machine throttles back sensitivity.   
      By how much does it do this? What would be the sensitivity when the black sand indicator is active at 17?
      This leads me to wonder. If running at 25 sensitivity and the machine encounters black sand, is it going to be a higher number than the previous scenario?
      I also realize, that at 25 the machine will probably throttle back sensitivity much sooner than at 17...
      Just curious, thanks!

      Nuggets found using Gold Mode, MF (multifrequency). Largest 9.8 grains, two smaller 0.6 grains each. Full report here.
       
      OK, there has been a lot of speculation on Gold Mode, and with Equinox shipping out in the next couple weeks I can now offer the basics.
      Gold Mode is designed to help optimise the finding of very small items. That normally means small gold to most people, so it has been called Gold Mode.
      A question that has been asked a lot. Is Gold Mode a true threshold based all metal mode? Not as I would define it. 
      On many VLF detectors a true, raw, unfiltered response can be seen via some pinpoint modes. All metal non-motion response.
      Next would be a motion based "first derivative" all metal mode, that basically adds motion filtering to the raw pinpoint signal in an attempt to keep an even threshold while in motion. This mode has no discrimination capability at all and just signals targets. This is the classic "true" all metal mode used on early induction balance prospecting detectors. Next would be "second derivative" filtering that is the classic motion based discrimination we see on most detectors today.
      Then along came dual channel processing. Many detectors started layering a visual discrimination channel onto the all metal channel, creating detectors like the that have a visual target id while in audio all metal mode. The X-Terra also has what is called "Iron Mask" while in Prospect Mode, which apparently incorporates a ferrous reject into the channel or employs a layered parallel channel. I don't know the technicalities, just that the feature is there.
      Are these "true" all metal modes? Not by old school definitions. And so to me at least Gold Mode does not fit that particular definition. The threshold, while it exists, responds more to items that are nulling on masked items (which may include ground and some hot rocks) than to ground variations in the classic sense as would be expected of a pure all metal mode. However, the extra capability offered sure does not have me pining for a true threshold based all metal mode.
      Gold Mode can run at MF (multifrequency), or 20 kHz or 40 khz. It does fit the definition of being an all metal mode by not being able to employ target tone identifications as is available in all other modes. You have a single tone, but it is adjustable for pitch. You do however have full time on screen target id numbers displayed at all times so you do have visual discrimination ability, but Gold Mode goes one more step, and you can also block/mask/notch just like you can in other modes. This is particularly important for the very low numbers down around -9 and -8 as some ground and hot rock responses roll in around there. Blocking low end ground responses causes the threshold to null (assuming you have it set loud enough to hear it) and so the nulling effects can alert you to ground changes and a possible need to tweak the ground balance if you are running in manual.
      However, what makes Gold Mode different in my mind is the processing, and in particular the audio, which employs a VCO based boosted audio that conveys the target in a way that gives a fuller picture of target intensity. The other modes have the standard Minelab modulated "beep" that simply gets weaker or stronger depending on the size and depth of target. The Gold Mode VCO based "rising/falling" response is more akin to what is seen in machines that produce that "zippy" response on tiny targets.
      The bottom line is Gold Mode can provide stronger audio responses on tiny targets. The large coil is fighting this a bit as a smaller coil or an elliptical will provide even tighter, zippier responses.
      The Gold Mode is not an automatic magical solution; it is simply a mode processed in a different way that can be advantageous in some situations and not in others. I expect given how some of us are very particular about how machines sound and act that this will be a mode some people really love and others might hate. VCO tends to have that effect on people.
      To sum up, Gold Mode is optimized for tiny targets, the most obvious way being with a boosted VCO type response on tiny targets, but there may be more to it than that I am unaware of. It does have both volume and threshold controls and while it is monotone the pitch can be varied. There is full time on screen (LCD) target id information as will as the ability to individually mask responses, mostly intended for hot ground/hot rock/ferrous responses but it may be used on non-ferrous targets also.
      Anyway, for those who think this is a key issue for them between Equinox 600 and Equinox 800 I wanted to try and clarify this a bit while people are still in pre-order mode in case people want to rethink things. To me the Equinox 800 is something I have to have based on the audio and other advanced tuning options, and Gold Mode is just an excellent bonus. in other words, I would still get the Equinox 800 even if Gold Mode did not exist. That's just me however and for others that lean differently hopefully this helps you out.

      Having been in and out of detecting for the last 35 years, decided to get back into it after selling all my equipment 2 years ago.  Bought an Equinox 600 and plan on trying it out next week on the coast, the only unfrozen ground in my area. Really looking forward to getting used to it since it is quite different than my prior Fisher CZ-21. My plan for this season is to hit dry sand beaches, water shallows(since I don’t have waterproof headphones yet), school yards, parks, and old house foundations. I don’t plan on detecting deeper water for now, but towards the end of our short season here in Maine, I’ll give my detector a few good dunkings to see if it leaks. After reading some of this forums posts, I’m concerned about putting my season in jeopardy if it does leak. I would be interested in hearing from those of you who have NOT had problems detecting in say 5’ or so of water, especially fresh water. All my water hunting in the past has been in fresh water, not salt. Also, has ML corrected the problem with the “ears” of the coil breaking? From some of my reading here it seems to have been a problem.

      I guess we can’t add videos to our posts?  Anyway, the default  setting FE and F2 is 2.  I set out a gold ring, old square I ron nail, and quarter. With FE or F2 set at defaults of 2, it seems to mask these targets.  Set to zero all is good.  (This is an EQ600). This seems to contradict the original videos that came out when the detector did.  Beach2 program.

      Hi all ! and cheers for the add !

      I have had the Nox for nearly 3 years now and have finally bitten the bullet and grabbed a Monster 😁 also this morning Eyyyyhaaa !

      Now for the stupid first question (I've had a read and could not find anything in a post on it 😔)

      Has anyone here tried a Nox 15 inch coil on the Gold Monster.
      The Nox can run at 40mHz and the Monster runs 45mHz so pretty close there and I have read (not confirmed) elsewhere that the coils have proprietry chips in them to stop interchangeability.

      They both fit each others coils though even though some said the plugs would not but I have not been game to turn on the monster with the Nox's 15 inch coil plugged in.
      (Big chicken 🤣)
      The thought of the Monster with a 15 inch coil is so tempting
      So back to the big ask.
      Has anyone actually tried ?
       
      (Ps love my 2 nox 800s)
