Is it better to do manual balancing or autotracking in salt water? On dry sand I have not found great differences, but in sea water the doubt remains, it would seem that autotracking tends to eliminate weak signals, according to you which is the best solution?

I do not know...But, I would follow the Minelab recommendations to start. Then I would try both when in the salt...

beaches and soil vary widely...find your own way.

Here equinox 800  is used mainly in the sea and  it is proving superior to excalibur, we are trying to use it to its maximum performance, so we try to understand what is the best condition and the ground balance is one of these.

For what it is worth here is how I do it. I use both. My beach is mostly fairly uniform and when I am in that area I usually turn off the auto ground balancing just in case it starts to track out weak signals.

The ocean as the ultimate sorter and classifier makes these wonderful pockets of sand that are really mineralized and "usually" has many more targets. When I get in these areas I turn on the tracking.

 

Where I am on the far north coast of California there is abundant black sand. The less mineralized areas typically show ground balance numbers of 14, the high areas jump to 60 and more.

I can't prove the auto tracking tunes out the really faint signals because that's the nature of really weak signals, right?

I don't think you can go too far wrong running in auto ground balance it's what I usually do.

 

Cheers,

Tim

When I hunt salt water, my Equinox is fully submerged 8 hours a day, on occasion 10 hrs if I'm doing well.  I prefer to do Manual GB, but not all folks know what they're doing & if you don't, Auto GB is ok.  Most my salt water hunts are on the Eastern side, so the black sands are not as strong as the Western beaches.

Keep us informed on what you find that works best for you.

I normally try to manually GB mid wet sand before getting in the water.   A lot depends on IF your beaches allow a GB .... sometimes mine wont and the machine will just grab a digit.... move a foot and it will change.   A few ways ive tried...... tracking can give you some sore of idea as to the digit you are working with.   There can be a pretty good swing of digits from DRY .... to WET to near the surf.   Near the surf i dont GB...... most of the black sand accumulates there... and there is water movement in the sand as the surf comes in.... which can really swing the GB and eliminate smaller gold.   Some just use default GB of 0..... and deal with the chatter from minerals.   There may be some advantage to this....... you cant tell when you are working in fluffy sand or near the hard pan out there just by the mineral chatter.   Some like to work with a really quiet machine too.  Tracking, higher recovery, lower sensitivity can do this....... but are you loosing deeper targets.... there is always a trade off.

The last day I hunted because of this thread, I switched between manual and auto GB. In manual I had it set at zero. EVERY target dug I went into each of the GB modes. I did not notice a depth increase over another mode. 

The only thing I noted was a little more stability [quiet running] in tracking GB with moving salt water up and down the beach.

Which is exactly why ML recommends using tracking GB in that particular situation (user guide p. 41)

It might also depend on how its tracking.   If its just tracking the minerals in the sand ....... OR if it also tracking the salt water.   Shallow water for the most part isnt an issue..... its a pretty forgiving GB.   But things change more for me the closer i get to the hard pan..... out chest deep.   But that areas can make most machines want to false a bit more..... the trick is getting it to smooth down a bit to catch weak targets..... with out over balancing loosing them.

      Finally go the video finished of comparing equinox 800 to the gold monster 1000 on in-situ targets in the field.  This is my no mean the comprehensive review as im sure the settings on the equinox could be tweaked more produce even better results.  But from what i saw on my ground they were vary evenly matched.  The gold monster seemed to pop a little harder on the targets, but the equinox still hit all the targets the gm1000 hit.  Since i detect mainly creeks the equinox has a leg up since its water proof and i dont have to worry about it getting wet or falling in the creek.  Hope you guys enjoy the video and ill take more footage as i work this little patch.

      I was able to get back to my 1850's site early this morning for an all day hunt. First half of the day was slow, only a couple of trouser buttons, a percussion cap and some lead. The latter half of the day finally started to get a bit more exciting with 4 buttons, more percussion caps and some misc, pieces of flat brass debris and more lead.
      Running my Nox as follows.
      11" coil
      2-tones
      recovery 6
      iron bias 0
      tone break at -9 to +9
      sens 23
      Park 1

      Hello, 
      I've been using the machine for a couple of months now with some good results. 
      I've been mainly hunting in Park 2 and Field 2 modes, even though under certain conditions they produce  additional noise. 
      For now, I would not like to modify any of the factory presets in any mode.
      I've been staying away from park 1 because of the high iron bias setup as it can truly mask some good targets in trashy conditions. However, the detector is really quiet in Park 1 and if you have a signal, it is usually something decent. 
      Field 1 on the other hand has 2 tones and 0 iron bias. I've been wondering if anyone here has any experience using Field 1 in the field ? Is it still quiet, even though the iron bias is set to 0?
      Would be great if anyone could share an opinion on Field 1 mode. 
       
      Regards, 
      Igor

      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+

      I had another great day hunting for WW2 relics today. I went back to where I had done pretty good last week and wasn't disappointed. I didn't find any silver coins today, just 3 wheats, but, I did manage to unearth some rather cool finds. The large round item with the eagle on it is sterling silver along with the medallion and the 1st lieutenant bar. Also found the usual eagle and collar buttons along with some other relics. I haven't had a chance to see if I can track down the family yet, I'll start looking later tonight or tomorrow. Thanks for looking.
