  1. Thanks my friend! Fingers crossed it will! 🙂 Will share experiences soon!
  2. Hey Joe...since theory is the same, I'm expecting it to apply regardless the machine. And I found numerous posts and guys using this trick...especially old timers.... However, which offset you will apply (negative or positive) has to do with the conditions first, and of course the reason you wanna mess with it. Common application is slightly negative when inland to run just a little hotter and help detect deep silver coins in hot grounds for example, or slightly positive when in salt to not completelly eliminate the tiny gold signals that are overlaping with salt itself. I have kept a phr
  3. Kac yes, the last video is with an Impact indeed. However, if you remember the 1st video of this thread (which caused my curiosity), the same guy was using this GB positive offset trick with a Multi Kruzer @19khz in beach mode...not with an Impact! The Impact video above just shows how GB Offset works in more detail and helps to understand this easier. Also, it's obvious that as he also states, a slightly possitive offset (to allow small gold signals to not be cancelled), means a slight increase of the GB value from whatever the auto GB value is for salt in our area....so if auto GB shows
  4. Thanks 🙂 Your "squelch control" similarity pretty much describes the actual GB outcome. At a moment, I thought that I forced this thread on the "overthinking" side a bit, but in the end I'm really glad that I understood how this GB offset thing could work for my benefit if conditions allow, especially in salt underwater where I'm after every possible gold piece... Glad you liked it 🙂
  5. A little update for anyone interested: the video below shows that my final conclusions some posts ago for the GB positive offset while in salt were correct, and can be used for our benefit if conditions allow. When auto ground balancing in salt water, seems that the detector performs a pretty aggressive (more than needed) auto salt cancelling in order to completely eliminate the salt signal, usually settling down to the lowest GB value of 00. As we know, tiny low conductive targets (small gold...chains, earrings etc) overlap within the salt range, so when we completelly eliminating the salt si
  6. Kac, Rick, many thanks for your replies guys....much appreciated. Hope to have a new MK soon in my hands to clear everything out...theory is nice (especially in quarantine time) & learned a lot already through our converstations to shorten my learning curve some (I always do this "learning preparation" while I wait for a new detector...you can call it excitement!), but nothing compares to real testing of our new toys 🙂 Have a nice weekend
  7. ps....nice to know that Tracking will work ok on the beach...will definetely try that, (but will also check if there's any risk of cancelling staff when using it), thanks
  8. Oh...if that's the case, it could explain my frustration (and will also correlate with the manual)... maybe I had missunderstood some posts from the other sources and got it backwards indeed...thanks! So...if wanna give a little depth boost for fringe deep targets (especially for high conductors like silver coins) => put GB in a slightly lower value (this is "negative GB offset" & ground noise will increase when raising the coil of the ground). Exactly like Kac was experiencing with his AT Pro as mentioned above, and as I also remember experiencing with my Deus....slightly lower (
  9. Thanks Kac & Rick Yes, I quited overthinking about it since I don't see further interest in this thread... Was just this Kruzer's salt water-gold chain test video which made me curious to search about it, and wanted to understand why he increased his ground balance value. Based on your replies and some further reading from multiple resources, I thought I've grabed the basics of the GB offset...Most seems to conclude that: - negative offset (lower value than actual ground phase) means slight increase in noise as the coil approaches the ground => some extra depth abilities
  10. Based on all the above info, and in order to conclude: - slightly negative GB offset => slight increase in noise as the coil approaches the ground => machine runs hotter => more depth in bad hot soils - slightly positive GB offset => slight increase in noise as the coil is lifted off the ground => machine more quiet/steady => increased detectability of smaller low conductors Makes sense? Lastly, Multi Kruzer's manual states that: "If the sound gets higher when lifting off the search coil above the ground, the ground balance value is too low, in other words
  11. I will also add some interesting comments via other sources (DD forum) regarding the same subject, that I just found and may solve the Ground Balance offset mistery: From Keith Southern: "I adjust my ground balance negative in disc mode till I get some ground noise feed back then set it back up slightly till it just barely makes noise....this helps when running it in disc mode to obtain more depth.... Do a simple test in your yard...bury a target to the fring depth so you just cant hear it on your machine when properly ground balanced.....say a dime at 9 - 10 inches..then turn you groun
  12. Truth is that I wouldn't even remember this Ground Balance Offset thing if I hadn't watch the formentioned video...but as I was seeking for Multi Kruzer reviews, the video that I posted earlier with this positive GB Offset trick in the salt water grabed my attention, so I brought it on the table for further discussion and explanations. I would also suggest to watch another video (attached below) where the same guy (!!!) shows what happens in salt water when he doesn't ground balance his ATX for salt, vs what happens when he does ground balance it to substract the salt signal...result is h
  13. I know that for many old timers, GB offset (positive/negative) was a common practice from what I've read so far... my experience is really limited but I do recall different results when messing with the ground phase value with some of my previously owned machines in difficult targets (like the 9'' dime detectability in hot ground as stated in my first post). Anyway, thank you all for you answers & comments. It's not a very popular subject but would be good to know the theory behind Ground Balance Offseting...at least the basics of it. As I understand it, is like fooling the machine (v
  14. That's exactly the effect I remember having with my old XP Deus when using GB manual offset from the real ground phase. Setting a little higher from the actual ground phase (eg from 70 to 75 as in my example for the Kruzer) was causing less noise but a 9'' silver dime had much more difficulties to be detected. Instead, when setting the GB a little lower than actual ground phase (eg from 70 to 65 as in my example for the kruzer) the 9'' Dime would become crystal clear and strong, but I had a little more ground noise and sound spikes... So, taking into account the first part of your answer,
  15. Hey guys, Can someone explain to me in simple terms what is it and what we accomplish by using a slight ground balance offset (either positive or negative) on our machines? I remember for example that when using an Xp Deus in the past, whenever I needed some little extra depth boost I was manually set the GB a little lower than the actual ground phase of my area but in the expense of greater ground noise and instability...the opposite when I needed a more quiet run....However I never deep dived into this concept and never understood how and why this really worked. Would be great to unde
