I have been also researching the NO GB mode 16 on the QED and found this from Howard the maker of the QED

When in MODE 16 the GB manual adjustment is still active and it can be used to adjust the sample delay. Lowering it from the default of 100 to 1 will decrease the sample delay by 2uS resulting in better detection distance on small items ie fine gold chains etc.
It's certainly going to be worth giving it a shot too.

I regret not experimenting with Coin/Relic more in mild ground. Pure PI mode with no ground balance and therefore no “holes”. Even at very low gain levels it might reveal shallow gold missed simply because it fell into the hole created by any PI detector that ground balances.

:smile:

Steve, when you say no ground balance, does this mean you don't have to depress the green button and pump the coil, or have I misunderstood?

Thanks,

Brian.

I misspoke earlier and slightly modified my earlier posts... Coin/Relic has very minimal ground balancing and so button should work if the ground allows, which it may not. And then you can shut GB Off via the settings, in which case the button will do nothing.

I never really tried it myself and see little evidence many have so this is sort of unexplored territory.

"Coin/Relic is designed for use in lightly mineralized soils including many beaches. It offers maximum detection depth on a range of target sizes, significantly greater than any other timings (emphasis added). However, if the ground is any more than lightly mineralized, the detector may not ground balance. Coin/Relic should work very well in most common parks, ovals, and old home sites, so is the preferred timing when using your detector for coins, jewelry and relics. On ocean beaches containing significant quantities of black sand, better results may be had by using Normal or Salt settings."

In other words, by design the Coin & Relic timing is already using an extremely limited amount of ground balancing, so minimal that ground balancing simply will not work at most locations if you use this timing. The first clue will be that the detector will pick up the ground if the coil is raised and lowered over the ground, despite any changes to the ground balance settings.

You can also turn the ground balance off completely off via the settings. “GB Off switches the ground balance circuit off for maximum depth in very mild soils, sand etc.”

and

”(Ground Balance) Off
In very benign soils, such as non-mineralised loam or sand, there can be very little and sometimes no ground effect. These areas are quite rare but are identified when your ground balance doesn't appear to be doing anything. By switching the GB Type to Off you can achieve improved depth and sensitivity.

This feature will most likely be used by beach hunters, or inland treasure/relic seekers, as it is extremely rare to encounter a spot in the gold field where Ground Balance is not required.

Procedure:
Raise the coil off the ground, away from metal objects, and switch to GB Off. After the tone is heard you can commence detecting.“

I'll be honest, I don't need to ground balance my GPX at most of our gold spots, sometimes I forget to to do it, I simply don't need to, I can raise and lower my coil without any issues, same with my QED... I can switch it on and use it in most places so much so to the point I contacted Reg asking how to ground balance it as it has a video showing it being done and I wasn't getting any of the ground feedback that was in the video so I had no sounds to ground balance out. The auto ground balance button did nothing and manually seemed pointless as there was no noise at all for most of the balance range numbers unless I went way out of default.   I have since found areas I need to balance so I've worked out how to do it now ?

When I got the GPX I thought my Quick track green button didn't work, same reason.

I try to remember to ground balance as I know a properly balanced machine performs better.

I was always a bit puzzled when really new to detecting about ground balance as my VFL's were the same, it didn't seem to make a difference as I never had the ground noise people talk of.

I look forward to trying out these new timings, the weather hasn't been playing nicely, we are finally getting some good winter snow and skiing is taking up a lot of my prospecting time at the moment.

Have you ever tried the Coin/Relic mode Simon?  I would think that in your mild soils, this timing would give you the biggest bang.  Let us know if you try it out and your thoughts please.

No I haven't, I didn't know to try it until Steve pointed it out the other day when I was questioning it, I'm looking forward to trying it out, it may be my secret weapon ?  Well, maybe not so secret anymore.  It's raining/snowing for most of the next few days by the look of it so I'm waiting patiently for a suitable opportunity.

      Can you guys suggest me a country that let people pan for gold without any / or special permission ? 
      My goal is to make over $100 Everyday 
      Thank you in advance

      Recently read Lucky's post about his Rye Patch adventure.  Nice job guys and gal.  He mentioned "we cover hundreds of acres with our coils a day".  I'm pretty sure he didn't mean that literally, it just felt that way.  Anyway, it got me wondering how much ground are we covering with our coil in day.
      For the sake of simplicity let's assume we are swinging a 12" coil in a 6' arc.  Therefore we cover 6 sq. ft each swing.  To cover an acre (43560 sq. ft) we need to make 43560/6=7260 swings.  Also let's assume we are taking 3 sec./swing.  Then 7260 swings x 3 sec/swing=21780 sec or 21780/3600sec/hr=6.05 hrs.  So to put your coil over an acre of ground with a modest swing rate takes about 6 hours excluding any digging, eating, or whatever.
      You could cut that time by swinging faster or using a bigger coil, but covering an acre takes a fairly long time.  You also could move faster and pass over ground between each swing, but your coil is still only seeing one acre.  Food for thought.
      Damn, I got to get a hobby.

      Xp deus shaft docs gold screamer and a few different wireless options! Finally got all the peices. Of course I got a bum connector peices for the aptx blue tooth so that will have to wait. I did test it but I had to keep my fingers on the connection while I used it. I must say sounded perfect, there was no lag as far as I could tell. Ready to stuff it in the pack and go find some gold!

      We all know it, but how many of us actually do it?  I'm talking about asking your friends and total strangers about places to hunt.  Many old timers know about places that no one else does.  And they know other people who know places, and they know people, and so on.  Once you gain their trust and are honest and straightforward with them, all kinds of doors can be opened to you.
      Here is a perfect example;  It's actually a long story how this came about but suffice to say, this little piece came from an "estate" that her late husband had acquired many years before.  This, along with several antique tools, were bought for less than $50.  She had no use for them anymore and had no family members that were interested.
      I've looked online for similar items but haven't found anything this big or impressive out there.  There is a small label on the back that says "Anaconda mine".  No idea which one as there are at least three of them in the west.  In the direct sunlight the display of color is breathtaking!

      Will be out in Littleton....Boulder area for 3 - 4 weeks. Would like to do some nugget shooting (maybe panning) while Im out there in Sept. Any areas anyone would suggest, in say a 50-100 miles of either place? Will have my Gold Bug Pro and pans. Never have done any nugget shooting been detecting for 50 plus years.
