Issue With Axiom And Ground Noise

I hope your evaluation of the 12x7 is a premonition of my own experience next month.....only been waiting since June. I will be using nothing else for a long time methinks, even though I was lucky enuff to receive a 'good' 11" with my 6000.

 

Been there, done that. I was a big fan of buying new gear, eating steak, drinking whiskey each night on the good weeks......not a fan of eating 2 year old spaghetti from a tin and not even a beer for a wash-down on the bad weeks....  Always best to have a back-up source of income before heading out 'professional'.   Thankfully, these days even 5 grams of gold a week with a 6000 can keep you in food, fuel and a little grog if you live rough in the bush.

If you have had a 7 and put the NF 12” Z search on it, that kind of parallels the 12 x 7 Exceed on 6000 experience except with 6000 the tone doesn’t change.
Rohans coils make 6000 what it should have been when you buy it new.
Smoother, quieter and reliable. Bear in mind you do sacrifice some depth with the 12 x 7 but most laterite gravel areas we detect are quite shallow so not really a concern for us.
Personally, the 16 x 10 will be my go to coil when they are available.
Deeper than the standard 11” but still able to poke it under a bush or in between some rocks. While Steve was in Meekatharra with JP and son he saw this coil in action and I think would back me up that its ‘the shit’.
Two weeks ago I had a play with the 9” round Coiltek and was hugely impressed.
Im not a Coiltek person (Holden/Ford) but to go over it just once more and make absolutely sure you leave not a single crumb behind, this is the coil to have. Obviously not as deep as the standard 11” but more sensitive that the man in the canoe.

Yes, full time prospecting, (professional suggests ability’s I don’t possess at anything other than masturbation), is a roller coaster ride off feast or famine.
Two years ago, before 6000, gay prostitution was looking viable.
Then along came 6000 and last year was best ever. Over a kilo.
Now, with Axiom, 6000 and for those 2 day drives down bush tracks looking for virgin ground (as rare as a real virgin in this day and age), the 7000, we can walk away from a patch pretty confident that we got everything there is to get.

The old joke, how do you make $500,000.00 prospecting? Start with a million.

Maybe Im missing something in this very long thread, but GB states that in other locations, the Axiom runs amazingly well? Im thinking that the knock noise is a coil axis issue due to the severe soil. In these mineral soil conditions, the soil becomes conductive like salt but worse.  In the zinc soil I mentioned, the Geologists could run a DC current thru the dirt for several meters. The earth field becomes amplified also. But like you said Steve, without physically being there, its all guess work and we could all be completely wrong....

Turns out it’s not actually a location based issue but only crops up on random power cycles.
Tried cycling it maybe 20 times today but would not drop out the fault.

I concur. The 9 Goldhawk is a delight, and it is my to-go coil for the 6k in tighter areas (for more open ground I mostly use the Z/NF12). I didn't do the 6k fix as I am only running with BT without ever using the internal speaker, and with the 9 inch Coiltek I have no EMI issues to an extent that would require a potential fix. I am usually a NF guy (12 NF-Zsearch is probably the best coil I have ever owned), but US-supply is a huge challenge with no (reliable) delivery date in site for the Xceeds (sigh). One thing I will continue to monitor is the Axiom's ability to find fast gold at some depth while running smooth in hot ground (7-9 ground by your definition). That to me is where the sweet spot will be. I want to see what sensitivity is left while "quiet", and at what depth. Just a smooth threshold in hot ground won't make the pill box rattle. There have been some very promising reports on DP by the early testers, but I want to hear this from retail operators who actually paid for their machines, without any promotional incentive or dealer's background, and who will have a hard (and skeptical) look at it (e.g. you-once machine fixed, Norvic, others.).

I’ve never bothered with the speaker fix either. Always use a Boss electric guitar wi fi trans receive setup, Bounty Booster amp and ZX Pro headphones.

Agree on NF. Every detector I have purchased for gold has had a NF coil and none have ever failed or been an issue in any way.
Impossible to even guess a percentage of improvement Rohans coils give you but I would be certain they cover their cost many times over.
Smooth on hot ground is good but a frisbee on the end of a stick will run smooth on a sheet of 1/2 inch steel plate so you are absolutely correct, there is more to it than that.
I am quietly confident and have experienced sensitivity 8 on what I consider difficult verging on extreme ground still hit that shotgun pellet at 4 inches and a .22 projectile at 11 inches before it crapped out.
Wanted to weigh the projectile but threw it in the bloody bin with the rest of the trash.
Need a trained raccoon to go in and get it for me.
Unfortunately, every man and his trained raccoon has a detector now and the game has predominantly become one of bulk sub grammers to make up your required weight.
6000 made that viable and given my experience with Axiom so far, I do believe it will get more of those small nuggets but obviously any attempt to accurately determine how much more would be speculation at this point.

For me, even if it only matches 6000 in recovered gold, it’s operational weight, comfort, build quality, (yes, I know), an external speaker that is up to the task and not from the back page of a Radio Shack catalog, available range of coils both Garrett and others, battery life, settings etc etc make it worthwhile.
As I’ve said, my biggest dislike is the unit being shipped with headphones from the set of Flying High.
A good set of cans (audio reproduction, not human reproduction) plugged in to Axiom is kind of like the Z search coil on 7000. It really does bring the audio to life and are a must have on days that are too windy to rely on the speaker.
This started as a thread on a dodgy Axiom but once I get a replacement unit I will keep updating with success/failures.

Replacement Axiom in hand.

Your back!! and good to see Gone Bush. And a good result in the end, good on to your dealer for the excellent service he gave you over the holiday season.

Watched your YouTube and best description I have seen yet. Fully understand re the threshold pitch, so a setting of 80 I think you said is that high or low tone?

Really good outcome. I think I have made up my mind now on which way to go, that won't be until April, hope there's still plenty of stock by then.

Cheers, Peter

I'm glad your dealer was able to quickly get a new detector into your hands. The old one was "tainted" by your experience with it, and you may never really have trusted it, even if it was fixed to be good as new. And more to the point, that would have taken much longer. Looks like 2023 is off to a better start than 2022 ended on.

Thanks for the video, I liked your description of how the targets appear more defined in the threshold of the Axiom, and how it has less response to variable ground by not being so sensitive towards changes in the ground with it's better ground handling. 

I think once the aftermarket coil manufacturers start to tinker they'll be able to work some magic with the Axiom. 

The one thing missing I'd love that's missing on the 6000 is a way to turn it's ground tracking off, and the Axiom has that ability.  I'm glad Garrett didn't take the fully automatic path and left settings adjustments there, just enough settings to give the necessary control while still keeping it simple to use and it sounds like you'll be able to use these settings to your advantage for sure.

Glad you got it all sorted, and you're probably right, it's better a dud like that went to someone experienced like you as if it went to a newbie they'd never know it was a dud.  This is one of the concerns with the 6000 with it's faulty coils and EMI problems, how many people are out there that don't even know they've got a problematic one as they just don't have the experience to know how it should behave, especially when the detector is marketed towards anyone turning beginners to experts.

Hi Peter,

Lower numbers is lower tones and vice versa.

Having never taken all that much notice of tones before, especially when the 6000 is take it or leave it, I was quite surprised at just how much of a difference it makes when you make the effort to narrow down a tone that suits your own hearing abilities.
Probalby should have mentioned that it is beneficial to temporarily revert to a tone that doesn’t suit you as a demonstration of just how much tone adjustment helps.
