You will shortly. I have had a couple of videos ready to go for about a year. The Level 4 modified 5000 with suitable coils is impressive! Will probably be in 2~3 weeks from now, just waiting for the planets to align ;)

@detectronicsaustralia3362 cool thanks, mate. I'm on your list to mod my 5000 and can't wait. lol exciting

Yeah, all of my old videos are hard to hear and the mods from this video are outdated anyway. If you'd like to see a video that you can actually hear that was produced by someone who had the time to do it nicely then check out eurekagold. th-cam.com/users/results?search_query=eurekagold

In this video I am running the older level 3 mods. Not long after this video was published we started doing level 4 mods which run much higher frequency and gain. I have been so busy since that I have not put up a video showing the level 4 mods in action. The level 4 mods have found several extra targets in my test patch and made targets that were just a whisper with the older mods scream out in pain like they are junk targets. The level 4 mods match or better the 6000 on the tiniest most difficult(wirey fine specimens) targets and also has settings for larger deeper gold too.

I tried the 12x8 evo and 12" round evo and the sdc did not like them at all. It was very difficult to find coils that would work properly on the sdc and that being said, larger coils were just miserable on depth to real gold nuggets worth digging. The machine is designed for small gold with small coils. If you want a machine that surpasses the sdc for sensitivity and at the same time get better depth, with the ability to use larger coils efectively, consider the modified GPX5000. It runs rings around the sdc.

No, I have abandoned developing the SDC mods. Too noisy and the depth on larger gold was very miserable, coils that actually worked were too hard to find. The GPX5000 can be improved far beyond anything the sdc could ever do both for sensitivity to the smallest most difficult gold to larger deep gold.

"One thing I can’t understand is whether they release a modified Gpx 5000 like this or the regular Gpx 5000 is modified" This is a regular GPX5000 that I have modified.

Yeah, tell me about it. I had purchased a wireless mic, but the Android video recorder won't connect to it. I found this out after recording the video and the detector was gone. I sat on the video for a couple of months because the audio quality was so poor, but finally decided to just post it after showing a few people and could still hear it well enough. Listening with headphones is better. I have sorted the Mic issues now, so next time I make a video you should actually be able to hear me!

It would not matter what coil I was running. Between the standard and modified detector, the modified detector would get the same target at better depth. The 19" evo gets even better depth on the bullet than the 12" round evo, perhaps I should have used that.

If you have the option of getting a 5000, then get that as it has all the timings of the 4500 as well as Fine Gold, which gives you a bit more sensitivity and depth than what the 4500 can achieve. You can contact us at www.detectronicsaustralia.com Go to the contact page and fill that in.

I have found pieces with the Sadie so small they have been difficult to weigh, was possibly a 0.01. But that is also dependent on what machine is attached and what upgrades have been done to it. The 12x8 Evolution is just as sensitive with better coverage and better depth as well. Sometimes it's like electronic panning, thankfully you don't need to dig the dirt of every inch you cover!

@detectronicsaustralia3362 i use a 4500 with the 12-inch nf evo coil, and it's amazing what small targets it picks up. I was thinking about trying a sadie to be able to pick up the rough airy gold, which the 12 inch can't. I'm just not sure if it's worth it and if it will be much different to the 12

@@theboarhunter the Sadie or 12x8 will get smaller gold than the 12" round due to the tighter curve on the heal and toe of the coil. The Sadie you can poke into very tight places.

No. We never did offer the mods for the SDC. The videos were done as part of the testing of mods for the SDC and the conclusion was, coils that suit were too hard to find, running the same coil on a standard GPX4500 always gave better depth with nuggets and the extra sensitivity made the machine noisy and was comparable to running in mode 5. As the improvements were quite minimal vs the time effort and cost we have pretty much abandoned the SDC for mods. Not all was wasted though as things we learned were applied to our GPX mods to make the fantastic GPX mods that we now have, which have a significant improvement over a standard machine. We do repair SDC's however.

Thank you

where can I get the parts for this mod to make it myself regards Jesse?

@@jsaviationgaming9005 No so easy. I designed custom circuit boards for the mods on this. There is no instruction book on how to mod Minelab detectors. You first need to reverse engineer the detector or at least the sections you are interested in. Then suppliers like Mouser, Digikey and Element 14 will have all the parts you need.

Don’t you find using the advantage coil ,even though less noise,you lose depth?With not being able to run front end gain higher?

@@guywood6574 I can run the front end gain higher which I can’t using an evo . Unless ground is quiet but I’m usually in hot ground

@@eurekagold Here I can run both coils way passed 3 o’clock it’s I get more depth with the evo .I have some evolution coils they totally blank out anywhere near 3 o’clock.

@@guywood6574 I’m mainly using 18 inch advantage coil targeting 2 to 25 grams . In hot ground running frequency 1 to the big side . If I want to play around I’ll put a 12x7 set to tiny and target fly shit but you get a million pellets . So I wast to much time getting pellets . So that’s why I only use 18 now and target weight . Not pieces

@@guywood6574 I also have a 6000 . 7000 and 2200 . I found the mods make a difference . Every target I get I switch back to standard and check . And if it’s a deep groan I get the other machine s and test .

.1 at 12 inches, I really do find that hard to believe, 12 inches is a foot

Yes it is especially difficult to believe when you dig a hole like that and the nugget is only 0.1 gram! But it's happened so many times now...at least 25 digs of disbelief with this detector after only having it for about 5 months@@jonathanmillichip9296

Yes, sure is, this is the mods that we have been running for several years now.

Yes, pretty much any of the Evolution series should work, but bear in mind that they were designed to go on standard detectors, so there may be times when you can't get much more out of them. I think a few of the guys doing testing for Nugget Finder are now running modified detectors, so who knows what the future holds. As for the other brands, it is a case of trying them and now that you know how your machine should behave, you can judge if they are going to be of benefit.

I am coming to the conclusion that the 5000 is about the best and most versatile detector that they have ever made, especially after they are modified. Another great thing about them is they are completely repairable.

Another bonus, I won't be letting mine go anytime soon 😉

Thanks Harry, I'm glad you are having a ball with it! For the 15" coil, give me a call sometime and we'll have a chat about the problems your having I'll see what can be done.

As for you 15 inch if it’s an evo you’ll get more ground noise and more emi if you get an advantage 16 coil . You can pump front end gain higher , less emi and will target 1 - 15 grams much better . All targets will be on the down side. If targeting sub 1 gram use 12x8 advantage

@@eurekagold thanks for the advice I will take it on board, I have been told that the 25DD nugetfinder is a good coil with the mods have you had any experience with this coil?.

Hi Mick, it's been about 18 months now using the modded 5000 and I have persisted with the 15-inch EVO and I have finally mastered it, the 6000 was my go-to machine but I now prefer the 5000 it can ( IMO) outperform in bigger gold

The ground moaned and groaned and/or the targets had less response in normal and the other timings on the gpz.

Well that would have been useful to show , did you turn sensitivity down when it done this , did you use the ferrite ring. Also you use a after market coil on the 5000 why not do the same on the. 7000. I would just like to see a fair and unbiased test for once. With my own test I can tell you the the X coils on the 7000 out perform the standard coil by a mile , I understand why people wouldn’t use those coils due to the mods needed but is that any different to modifying a 5000 ? Also if you were to make a test pad knowing the exact size and depth of targets . I know testing takes a great deal of time and effort and I thank you for showing yours, it’s interesting but I think you could do greater things

@@markklau9158 Well I could have shown all the fiddling around, then the video ends up being 25~45 minutes long and everybody has lost interest. I had X coils there, but only had a short window to play with it, so chose the coil that every GPZ user has. At some point however, I would like to do each detector individually over the test patch running all different timings etc so all can see. I use the aftermarket coil on the 5000 because the standard coil falls over the moment you try to get more out of it with the modifications. That will be another video with the 5000 running the standard 11" mono over the test site. As for the test pad, the only target that I actually know what it is is the .22 pellet at 9", the rest are all targets that I have found and not dug. They could be gold, they could be rubbish, but likely undisturbed gold given the majority of other targets I have found there. I would also like to bury some targets of known size/depth, especially some deeper targets, any suggestions on what to use for targets? Anyone got a spare 80oz slug laying around :D. You see with testing, there is one crowd that says that test targets need to be undisturbed gold and then the other that want to know what size and depth. All I can offer on the undisturbed targets are guesses as to size and depth, given the responses from various detector/timing/coil combinations having used the test patch almost daily for well over a year. At some point in the next 12 months I want to set up some tubes in the creek bank like the Laanecoorie test site. And yes, testing takes a lot of time.

I look forward to seeing that

Thanks Guy! It's amazing what the mods can do. People are going back over their old "flogged out" patches and finding quite amazing amounts of gold given the work they previously did.

There may have been settings in the 7000 that would have smoothed it out, but anything I did to do that also diminished the target response. The modified 5000 was running gain and stabiliser somewhere from 6~8, motion very slow, quiet audio. There is a lot of room for adjustment.

Hi ya Mick, how do those targets go on the level 4 f1a4 just put of interest?

@@jasonreinders9725 the level 4 f1a4 picks them all up, but the 5000 does it better on all but the second target. That gap is closing however.

Unfortunately we abandoned the SDC mods as the overall improvement was not that good and the detector quite noisy. However, we learned a lot from the work on the SDC and applied it to the GPX mods we do and the improvements we do the GPX now are absolutely fantastic. One of our modified GPX5000's will beat an SDC, standard or modified, on just about any target, especially with recent improvements we have been working on.

Unfortunately I haven't had time to revisit the sdc mods. Some users have tried using a Sadie coil with the sdc and found them to work ok, but as for using bigger coils to detect bigger deeper gold, the sdc just isn't designed for it. If you want better depth with really good sensitivity, then the modified GPX5000 is the best way to go and is the most versatile machine.

Unfortunately we abandoned the mods for the SDC as while it is impressive on a coke can, when testing with real gold, the depth was really miserable, to the point where you could bolt that 18" coil on a standard 4500 and get much better depth and less ground noise. Also as the SDC is a noisier machine the gain control didn't really help the situation. Fortunately though, there were some really good lessons learned which led to our current Low noise RX Gain mod that is now used in the SD/GP and GPX series and provides unsurpassed performance without adding a heap of noise. I wish it had been a better outcome for the SDC, but the performance gains were just too small for the amount of work that had to go into it and selecting coils that would actually work was difficult. If you are really serious about getting better performance I can highly recommend our modified GPX5000, it gets the gold from small to large.

One would think so Brett, but as is clearly demonstrated in the video, when the detectors are set to standard they do not detect the piece of gold. I was most disappointed in the performance of the sdc and that is one of the many reasons I don't offer sdc modifications. If you are ever near Dunolly, Vic and would like to come past and verify that standard settings on the modified 5000 perform exactly the same as a standard 5000 detector on undisturbed in ground targets, you are more than welcome.

Hi Greg, that was 2 years ago! I was probably in "normal", but your "Normal" "Deep" and "Custom" settings are just labels and they are only what the label says when you have done a factory reset(excluding custom!) and not played with the settings in the back menu. The moment you change the gain, stabiliser, motion, audio etc in normal or deep, then technically it is no longer "Normal" or "Deep" The ground around there has some very hot pockets and also hotrocks scattered about the place. It may have been able to run normal timing, I don't know. Would normal have picked up that target? I don't know that either. To say it would or would not now is just pure speculation. If you are ever around Dunolly Vic, I'd be happy to show you and you can use whatever settings you like. Since this video was made there have been further improvements to the mods demonstrated.

Did I mention about 10% of your finds being mine? :D Hmmm, might have to start a commission based mod system! Good to hear that your modified detectors are still giving up the goods in those flogged out areas you like to go. I am getting many good reports trickling back with some sizable gold being found at depth too.

Well Bill it may have. I didn't try in standard settings, or other timings than fine gold, nor did I state or imply that a standard detector would not have found it. I just merely wanted to share how the modified detector operates in real world conditions and that it does indeed find gold.

@@detectronicsaustralia3362 understand that but what did the modifications achieve?

@@billgabriel8042 Improved sensitivity, target response and depth. I can walk and swing faster and find targets that you have to swing very slowly for with a standard detector and some targets that a standard detector won't detect no matter what timings or settings are used as they are just beyond the reach of a standard detector.

Yes, sure do. See DetectronicsAustralia.com for more info and contact details.

I wish I could give a solid answer on that! Since this video was taken we went into lockdown. In the mean time I have moved house and am playing catch up now. Once our wireless batteries are back on the shelf I'll have a bit more time for testing/refining the SDC mods.
