I have one of the blue SD-2200V2's and a hardly used smooth running GP-3000 that I am in no hurry to sell.  Yes I have the 2300, 5000 and 7000.  I do feel the newer flat winding coils are better.  One of my all time favorites was the orange CT 14" round MONO, then another gold getter for me was the NF 16" round SL MONO.  Yes I still use a DD coil in some of Idaho and Oregon as the iron trash just wears this old man out and DD is a must.  Another one of my favorite coils on the Minelabs is the Commander Semi Ellip 15" MONO.  Talk about a solid built coil that just performs.

As for the boosters...I pretty much stick with factory.

Mods to a detector.  If you are happy with the mods and feel it is working for you, then I'm happy for you.  I don't get any of my machines modded, but I am also still selling Minelabs, so it might not be wise for me to sell a Minelab and then tell the customer to get it modded.

Hey Gerry,

Sold any GPX4000's lately?  😄

I am happy with the mods.  Now I don't have to be curious about them anymore.  In some ways that was enough, but I'm still finding gold that other people missed, so there's that too.  I'll qualify that by adding that I haven't dug any huge nuggets or 1 grammers at two feet.  But if the machine is stable and quiet when others may not be, then there's an edge.  I also have less than the cost of a good used 5000 in it, so I don't feel I'm doing too bad considering the alternatives.  Lots of coil choices as well.

One thing I don't do is get all caught up in the 'hype' and controversy surrounding the mods.  I definitely don't say this is better than that, or whatever.  I also haven't said anything about it on this forum in almost two years.  Just so people don't get twerked about it. 🙃

When 'Mr. Phase Tech' posed his question I thought it would be a good opportunity to shed some light on the 'experiment' I've been conducting.  From the responses I've read in this thread, my 4000 is the only 'old tech' still getting regular use (primary detector) and finding gold.

So if we happen to cross paths in the future, you're welcome to try out my detector for the day and I'll keep it a secret for you. 😉

Im running a Gp Extreme ,modded by Woddy and have had it ,seems like 10 years.

Runs sweet and does the job really well.The Lucky LArk,Li Ion Battery combined with the Amp is all i need.Oh and a good set of headphones,Thanks Nenad!.

Actually i also use the Apple ear buds and find them excellent.

Regarding the machine,if any,the only gripe i have is the "Level Adjust".Which affects the pausing of tracking.Kinda does my head in ,regarding tracking out weak signals/combined with hot noisey ground at times.

Other than that very very stable.Huge improvement on hot rocks from stock....Gain control great,not to mention the wider Frequency adjustable pot...Thanks a bunch Peter!.

I run the 12 Inch EVO...Goes deep and also the 12 Advantage.Best all round coils in my opinion.

Hey Ash, 

Glad to hear that. 12" round or 12x7" in the advantage? 

Yes the level adjust was always a tricky one. I used to use Fixed in milder soils, and in variable ground when using Tracking, I found the Level Adjust on about 10 o'clock worked well. Later when I installed a tracking switch on the handle, I never (very rarely) used Tracking, as it was so much easier to control the machine. 

In very mild ground, running mono coils on Normal/DD position was deadly. 

One thing I could never really work out. On my GP extreme when using a Coiltek 14" Pro DD, it seemed to run better with my home made battery regulator set to 6.9 V. When I used the same system on the 3500 I seemed to get a more stable threshold running a stock 6V gel cell. Couldn't work that one out..... I later switched to the 15x12" Commander DD, running my regulator on 6.7V (unloaded) and that combo worked great. Medium tracking, Mono and Sens Extra could handle most of the soils here and got some good results.

Hi Guys,

These days I swing a GPX4500 and a SDC2300 that works for me and I love them, but still have a GP3000 that is a great little gold getter.  I have a sadie, a 14 x 9 evo as well as an occasional 14 inch DD on the 3000 , also a SPO1 booster that I got off you Nenad. 

Whilst i am not a supporter of modding I must admit I did get the tracking button put on my 3000 and a decent third party power supply that attaches to the detector saving on unnecessary trip leads that I seem to find,  also cutting down on weight. 

The 3000 still delivers, got this 10 grammer with the 14 x 9 evo in flogged out ground that has seen just about every machine go over the top only the other day close to home .  Only goes to show its still out there and no one gets it all.

 

Regards to all.

What you say,i agree with here."Best run in Fixed"and also with Level adjust lower down better when ground is mineralised.

I really need to get around to sorting out that tracking switch on the handle.Was yours a push and hold type(Like on 4500?) or a traditional switch?

Been so long since i set the "POT" in my lucky LArk battery(Voltage output) that from memory i thought the sd,s and the Gp,s were good to up to 7.3 Volts.So not sure why your machine as stated did what it did.

Anyway ,look forward to my Coil,yet to receive Nenad.

Actually also working on another!.The 9 Coilteck Elite,which id love to hear some views on or anything that can do the job as well as my regretfully sold SADIE.

Yeah I'd think like the 12x8" Evo, the 9" Elite may be too much for a GP machine, they are just too sensitive! Be dynamite in very mild soils though... 

My remote GB switch was literally a relocation of the control panel switch. I removed the switch and put a DC plug in it's place, so didn't have to drill the control panel. Then with a bit of boring on the handle, mounted the switch up there. It was forward for tracking, back for fixed. Worked great.

      This is a topic relevant to every(?) form of detecting -- ground coverage.  I'll list several questions concerns I've had but any replies of course aren't limited to these, nor do they need to address  any of them.  Just tossing out some ideas to prompt further discussion.
      1) What methods and efforts do you apply to ensure full ground coverage in the cases where that is one of your goals?
      2) Is your sweep a straight line path or an arc?
      3) How long is your sweep?
      4) How much do you overlap consecutive sweeps in the direction you walk?
      5) How much do you overlap side-to-side swings when following parallel paths (e.g. when walking two side-by-side swaths in the same direction how much does the left end of one path overlap the right end of the next path or vice-versa)?
      6) Have you ever measured your coverage?  How well do detectors with GPS (e.g. Minelab GPZ-7000 and Minelab CTX-3030) monitor ground coverage to this detail?  Have you used other devices to measure ground coverage.  E.g. I can imagine a drone with camera could provide useful data.  Are there smartphones app that would help quantify coverage?

      Just dreaming...
      What'dya think? Minelab technology going on the next moon mission?
      X6 must be space-worthy.

      If this question has been addressed elsewhere, I apologize in advance and hope someone can give me a link for it.  I have noticed that other companies besides Minelab are coming out with PI detectors for less than $3K.  How do these detectors compare to the best Minelab detectors for Gold and also relic hunting?

      On the Anfibio Multi (and I think Kruzer & others) there is a definite step in sensitivity between 39&40 Gain and again between 69&70 Gain. Is this a change in the Internal Threshold? In a way this would be the inverse of the way the F75 adjusts sensitivity according to Mike Hillis.  Regardless, it is a very good set up in difficult sites. Most NM users know about the difference in response speed between 89 & 90 Gain on 3DI. This is different. I had read about these steps in a forum post that quoted Alper of NM. I can't seem to find that post now that I want to re read it.

      https://patents.google.com/patent/WO2021016649A1/en?assignee=minelab&scholar&oq=minelab&sort=new
      This is the most out of this world Minelab detector patent I've ever read. There is so much here, some very sci-fi like, I don't even know where to start. My takeaway is they seem to be positioning themselves for a drone based detector eventually (main details in this patent could be easily transferred to a drone based platform - IMU, GPS, magnetometer, heads up display, FPV, remote control, robotic/vehicle mount, etc) . That is 100% a guess. But in the meantime, there is some interesting, novel items in the pipeline that we might actually see on a machine in closer future?
      No clue if this is a coin machine or gold machine or if it's something they are actually working on right now or just trying to get control patents on such things for the future which may or may not arrive. One thing is for certain, Minelab is BUSY in the engineering department. A few of the highlights:
      Heads up display over glasses/head mounted display (aka augmented reality). Settings, target visualization, shading of detected/not detected areas (I asked for this specifically 5 or 6 years ago here, awesome to see it in a patent now). Plus a camera showing the coil (why would you need that if not operating remotely as from a drone?) The detector has a camera, IMU (accelerometer) and magnetometer to determine position with accuracy. The IMU tracks the position of the coil in real time in relation to both the ground and the target, and combined with the camera video feed will provide a "visual" of the target in the ground through the glasses/head display, as in form of a heat map which increases accuracy with each pass of a coil over the target. A GPS tracks the machine position to properly map the IMU/coil visual target data on the ground and let's a user see the mapping as they detect. This data is recorded for future historical use and can be shared.  Centimeter accuracy with the visual target heat mapping. Potential operators/users include entities other than humans such as "robots" and "an AI (artificial intelligence) using a metal detector" and this line: "The metal detector may be handheld, mounted on a robotic arm of a vehicle or a robot."  Wireless connectivity to computers and phones, transfer of files containing settings configurations from instructors or expert users Remote control of the metal detector through apps on laptops or phones Ability to upload maps, including detecting data, historic human activity, buildings, or other items that seem to indicate custom mapping capability Internet connectivity, potential control through the internet (again, why if not for a drone type device?) "Teamspeak" to other detecting members in the area wirelessly Visual/spatial discrimination Accurate depth measurement Synthesized audio mode, eliminating noise completely and allowing the detector to "recreate" a synthetic audio stream based on data from prior swings Delayed audio processing (enhanced audio) mode or real time audio mode, ability to seperate multiple close targets, reason for this I venture a guess why below ---> This patent actually seems to be describing a completely new method of RX in a detector. Which is actually similar in some ways to the wacky idea I had years ago of reducing EMI/ground noise by emulating a radio telescope array. But in this case they appear to be describing a fairly ingenuous method of doing something similar with only one coil by monitoring RX of the same target at different points in the swing (with the IMU tracking these points) and combining all those RX signals. In this way (and this is my guess, the patent doesn't explain this), you can form a sort of comparator, gradiometer, or interferometer to seperate the wheat from the chaff, so to speak. If that's what they are doing, then I find it to be brilliant. If not, then I just gave them one hell of an idea to patent for the future. 
      That probably sounds like jibberish to non-engineers. But I want people to understand the brilliance in simple terms. Consider this: EMI is random. At any given point in your swing you'll get noise here, but not there. So if you compare two points in the same swing, you will hear noise one point but not the other point because the "zap" already ended. But you might hear a good target at both points in the swing since it's not random like EMI, it's always there in the ground. So, you can effectively eliminate EMI by comparing what signal is not there at two very close points in the swing, and keep the target since it's always there.
      Similarly, with ground, the ground changes as the alluvium changes since soil is inhomogeneous. But a target is still the target. So, a similar method can be applied to the ground.
      In theory, you could use ideas like this to essentially get rid of the Difficult type timings and keep your gains boosted high, and deal with EMI/ground in this way instead which does not require reducing sensitivity. A totally new, novel approach to RX in a metal detector. The audio processing is very slightly delayed because they are using that time to compare measurements at a few different coil positions before letting the audio processor signal that there is a target present. That's my guess. If that isn't what they are doing, then someone else should patent that and thank me for it later when Minelab buys it. Either way, they have something totally new in the RX department here. And the future of detecting looks bright and interesting to me still.

      Hello, now here’s an opener that might just get me banned on my first post!
      Bear with me, my intentions are pure :)
      Does anyone know if it would be possible to jam an MD signal? The reason I ask is to combat the evident problem we have in the UK with “nighthawks”, illegal detectorists.
      Over here, any landowner can grant permission for detecting on their land (with caveats, known historic sites are protected by law). What often happens is that such a permission is granted and a detectorist innocently sets about his / her business. Someone less scrupulous spots this person and assumes there may be something important there, so shows up at night with a couple of friends and the landowner awakens to a field / lawn full of holes, then bans metal detecting.
      Historic sites are also looted.
      Just an off the wall question, how tricky would it be to build a device to block this on a piece of land? Anyone any ideas?
