Title: Another new QED owner
Post by: Blip on Friday June 21 2019 12:46:51 AEST PM

Northeast, myself and my wife met Howard and his wife this morn. What a fantastic couple!

Howard is a bugger though! He upgraded my QED but refused to take any money. Oh this is one seriously light detector. The advancements this detector has over the one i bought recently is substantial.

Chatting to Howard over a coffee showed us how passionate he is with his ‘baby’ and what he has in the ‘works’. I find it hard to believe he sleeps at night with his mind ticking over as it does! For those of us fortunate to be involved in the QED by owning one, this detector will constantly be updated with improvements.

Awesome stuff mate. Hopefully when i get back on my feet (had all the titanium removed from my foot....oh except for two broken screws) i can post on some finds.

regards.

Al

When i first got the QED in its early configuration i didnt have any issues with performing a ground balance. Prior to sending it back to Howard for its upgrade i started to have difficulty getting a ground balance. Since receiving it back from Howard as a fully fledged PL2 i am still having troubles determining a ground balance which I initially hadnt. Originally it was straight forward and clear cut. Not now. I just cant seem to determine a ground balance.

Commander 11” mono, new. I do a factory reset then try a ground balance from here. Nope, just cant get a clear defined balance range like i could originally. I watch the ground balance vid. Nope, cant achieve the same. If i take the figure up to say 180-190 and hit the AGB, it didnt shift initially but eventually would only shift by two points at a time.

The only other coil i have is a Nugget Finder 20”. Ill give that a shot.

Cheers guys.

Al.

Gday Al,

Are you only performing an AGB or are you also trying to MGB.

Note that AGB works a treat when THS-B is set at exactly NULL, if you perform an AGB when not at NULL it will not work (anywhere) near as well.
Also the coil needs to be moved towards the ground in a very fast motion with the AGB button depressed but released before the coil touches the ground.

Another important point is that if the ground is (very) benign (ie not mineralised), then AGB will be problematic as it works by determining the difference between your current settings and the ground; in benign soil it won’t find the difference as your MGB leeway will be huge (I.e. the MGB range where the QED is in GB will be huge).

The MGB process is based on whether the pitch when lowering the coil is a rising pitch or a falling pitch; if rising pitch, lower the MGB; if falling pitch then raise the MGB. You should be able to get to a point where you get no noise when bobbing the coil, especially when lowering the coil. The MGB works regardless of your THS-B setting.

If you are still having problems, PM me and we’ll get it sorted.

Cheers Goldman

Hi Brian,

No def MGB mate. In its original config it didnt have AGB even though it had the button. MGB was very clearly defined. It was consistently around 110. Now (and prior to Howard doing the upgrade) i cant determine clear cut ground balance. Im guessing where it may be. THS-B no probs mate. Clear cut, no drama, set at null.

I prob shouldnt have mentioned the AGB as it hasnt been part of my ground balance issues. It was just something i tried to see if it could determine a ground balance that i couldnt.

I might see if i can catch up with Northeast to determine if there is something i may be doing wrong/different to previously. The thing is originally i had no issue getting a GB.

Al.

You're not holding your tongue right   ::62::

It was ground balancing OK that day I caught up with you when I had a go.   If you are still pressing the up or down buttons down when you are trying to ground balance - stop it!  Start somewhere near where you think it should be, bob the coil slowly up and down, move the up or down buttons only a few places, bob again, repeat until a nice, quiet GB.   

As I have not been using Null the AGB doesn't work that well so I just Manual GB  (thanks for that tip Goldman - until I knew about the Null I thought the AGB was a bit faulty). 

I haven't been able to get out and test it yet but I think Howard has also given me the answer to my 'perceived' issue with the Gain.   Perceived quite likely = inexperienced operator!

mine is the same config as the one in question, pl1 upgraded to pl2 specs, i always run in null, no matter which coil im using from 8" to 20", the agb works a treat hold it in lower coil and release agb before coil hits ground, i never use the mgb hardly ever, plus i run an amp and fully wireless with bt 4.0.

Im left tongued, that could be it!

Yeah alright alright ill get me finger off the button. How dare i follow the manual, lol!

try the agb in null ul b surprised makes life alot easier, can still get 0.02 of a gram with the 8" and 12" easily.  ::402::

Guys, after a reset, if i tried to set the ground balance by holding down the button i could not achieve a no noise period. Originally i had no problem achieving a GB by going by this method. It was clear and defined. Anyway going down or up as required by a couple of increments suggested by Northeast allowed me to find my GB.

Cheers guys.

Guys, today the QrED was running swt.
GB 130
THS-B 53
THS-A 70
Gain 10
Mode 3

Would i be better off running mode 2 with a gain at lower figure?

Is THS-A too high at 70 (too narrow at THS-B?)

Cheers guys.

Al.

Depends on coil size, thus target size your after.
Large coil,
Mode as low as you can GB, high to v high THS-A, THS-B = NULL or as high above NULL as you can get with as Gain as high as you can get but still 4+

Small coil
Mode as low as you can GB, THS-A between 40 to 60ish, THS-B as far below NULL as you can get (4-6 is good), Gain as high as you can get, but still 4+

Cheers Goldman

thats were i started when i first got mine around the 70 mark too, you will crank it up over time mate

To see what works best in your area do some tests, you may find that really low THS-B accentuates high mineralization (rising pitch ground noise responses) which is not what you want, if that’s the case, then use a THS-B close to NULL (not over NULL) and a very high THS-A, with Gain as high as you can get. Do some tests (dare I say it “air tests”) in both setups and see what works best for depth and signal with your coil in your area

Cheers Goldman

Air tests have their place mate, so all good!

I havent as yet ventured away from the basic settings as a learning curve so ive run THS-B at null. I havent bothered concentrated on smaller/larger (either side of null) targets just prefering to keeping my search neutral for the time being. But absolutely, ill do some tests.

Ever since BC mentioned in the GG&T magazine that for the 1st time an Air Test result was a good indication of what a PI could achieve through the ground then his words have stuck in my mind ever since and why I continue to evaluate a PI and Coils using Air Test results.

Each to their own as the saying goes.

I still have the GG&T magazine where that is stated.
