I was reading on another gold prospecting forum, a fellow was concerned about how robust the articulating coil connection might be on the new Minelab SDC 2300 metal detector, as well as some questions I have come up with, in regard to that detector.


I will continue that first thought here, rather than possibly compromise a potential sale by a reader of a forum, whose owner might be a Minelab dealer.


With regard to the coil's articulating joint:  I have no technical knowledge that would tell me how robust/water resistance that moveable joint might be or have, nor the longevity of such a joint, with respect to its electrical conductivity life expectancy.  I would think that the Minelab people had the same questions when the design was put forth for production, so I don't know why it should be a big secret for end users to know about, after all, it is a pretty penny to buy the machine, and you sure don't want it to go south on you right when the warranty expires, or even before for that matter...


My experience with the early Minelab XT's, was that there could have been a better way that would constrain that battery pack and limit it's ability to bang around within the confines of the control box. Plus, now that I think of it the battery box door was subject to falling out, and being lost, as an aside... 


If my memory is correct, those tiny wires that connected the battery to the circuit board were a single strand, a hard wire, as opposed to a more flexible multiple stranded wire.  In my case, the first time out with that machine, the battery module moved around so much within that control box, that the single wire broke.  End of that day's use, until I could resolder the wire back at home, and hoping it would work a little longer next time I went out.  The point of all of this is, we have come to expect a good product, that has been well thought out, and field tested to keep up spoiled Minelabbers happy, which I have been since the early 1990's.  I have never sent any of my Minelabs back for repairs.  None. Let's see:  XT16000, 17000, 18000, SD2100, GP3000,GP4000,GPX5000.  That is a lot of Minelabs. Plus many coils, many.  THAT is a lot of dollars worth of faith in their product.  Not a paid commercial...  :lol:


One other concern regards the use of "C" cells in the SDC2300.  The why of it, opposed to the use of them, as opposed to a lighter AA rechargeables, or maybe 9 volt batteries.  Could have to do with the "c" cells being more availability in Australia or???  I have become spoiled with the fast recharging lithium ion batteries.  Fast, with a quick turn around. Expen$ive: oh yes! 


I am curious about the turn around time of the "C" cell rechargeables.  I know that the old gel cell batteries did take some time to recharge, as do the AA rechargeables, so I guess the answer there, is to have spare sets of "c" batteries along to use, if you plan to have especially long detecting days.


Perhaps down the road, we will see a lighter lithium-ion battery setup that will provide a really fast turn around time.  Maybe that would help justify the inordinately high MSRP price of this little detector.  I DO understand the reason for pricing the detector at the level it is presently...    


I am pretty excited, stoked even, about this little articulator.  I am pretty sure there are a lot of people out there right now, drooling over their old maps, with the thought of resurrecting those old patches that were so good to us back in the day, plus other patches that remain to be discovered.


Thanks, Steve for making this forum kind available. 

I hope you are having a great time, and enjoying your chili supply, even finding a few nuggies with that SDC 2300.  Keep us in touch...

The joint seems pretty strong to me in my operation of the SDC. The only odd thing about it is that the detector coil rotates in a side to side direction that you are not used to. The C size batteries are not a problem. The SDC comes NiMH rechargeable batteries and a charging system.If it would have been built with AA Batteries, you would need to change them every couple hours, to about 4 times a day. AA size hold a lot less juice per charge than C size. The C size last about 7 or 8 hours per charge. To make sure my batteries last as long as I might need, I bought 2 extra sets of rechargeable C cells (8) off Amazon. I like my SDC and plan on using it quite a bit this summer.

      I bought a house in meadview about 4 years ago.  Every couple months when I go there I try to get over to gold basin to do some detecting or drywashing.  It took me a couple years to find my first nugget out there and its been a couple of years since then and I havent found another.  I swing an SDC and I've read people have done pretty good out there with that model.  I find plenty of lead and boot tacks a inch or two down but not much deeper than that.   What settings are people using out there?  How deep down are people finding the gold?  Would I be better off with a  different model that can go deeper?  I'm not very confident in my abilities since I learned this machine on my own and have only found 2 pieces in the 4 years and dozens of times I've used it.  Any advice would be appreciated.

      Here's the 1st video Minelab USA did for TV.  You might know the English sounding dude from FL.
      What's interesting is we were able to see Minelab Mine Detector as it turned into a gold detector.
      The comments towards the end about seeing what's in the ground before you dig it, I'm still waiting.
      Do you feel, we'll see a detector that can actually see the item or at least the shape of it with any accuracy and if so how long out?

      Another classic question,but i have a ctx3030 with 17inch coil and do mostly detecting in the saltwater.It goes deep and thats what i'm looking for,depth,,I know that SDC2300 is a PI machine and very sensitive to gold.But when it comes to depth comparison in saltwater and knowing the SDC2300 has 8 inch coil,then the question is which detector goes deeper?is it worth buying that expensive unit just for saltwater beahhunting?

      Glad to see Simon is back.
      I know there are previous posts about SDC battery compartment seal, I had problems with mine this summer.  
      Here is the background that I have posted about before.
      I dredge in an old cut that wasn’t cleaned that good into the bedrock.  The bedrock is a quartz muscovite schist that through frost shattering and dissolution is deeply weathered making it easy to dredge into for a couple of feet.  Because it is a cut the water is always murky and work is done by feel.  A couple of years ago I dug a big section that I thought was cleaned up.  Previously I seen a guy use an Excalibur to check where he had dredged so I took the SDC in.  There was targets so dredged deeper and recovered a couple more nuggets.  Now this has become standard practice.  
      This summer while changing the batteries there was water in the battery compartment.  I cleaned and dried the compartment.  Also cleaned the seal and the machine worked fine but I would like to change it.  Through a search nobody sells replacements?

      With the fantastic weather in the Rye Patch region during the month of October, I was chomping at the bit to get down there, but my summer job didn't end until the 30th. It still took me a few days afterward to get everything wrapped up, so I finally hit the road and met up with Gerry and friends at Rye Patch the following Tuesday. The detector training class we were scheduled to give that weekend ended up being cancelled, thanks to a winter storm that was forecast to move into the area on Friday. Needless to say, having only two days of optimal detecting conditions before being snowed out and forced to move on to Arizona was a total bummer.😞 Intent on finding a few bits of gold in-spite of the looming storm system and armed with our trusty Minelab GPZ 7000 gold detectors (and one SDC 2300 - also quite trusty, btw), we hit an old patch in hopes of digging up some previously overlooked yellow metal. Only two small nuggets were found after a couple of hours searching with four coils on the ground - not a very good start. It was then that I remembered another old patch nearby that I had completely forgotten about, it had been so long since I had been there. It wasn't a very good producer back in the day, but perhaps we would be able to find a few nuggets that the VLF and early PI machines may have left behind. Within minutes of hitting the ground, my good friend Chef Rusty and I both popped a shallow sub-gram nugget; not a bad start. Soon, everyone was digging good gold! My second target gave an obvious yet deep sounding signal response from the GPZ's stock 14” coil. I imagined it to be a three or four gram piece at a depth of 12” to 18”. Gerry noticed me digging quite an excavation and came over to capture the action on video. At a measured depth of 20”, the target was finally out of the hole, and as I held it aloft there was an audible gasp from the audience that had gathered to watch, followed by cheers and fist-bumps:

      After a thorough cleaning, the specimen weighed in at a whopping 40 grams - a totally unexpected and pleasant surprise! The nuggets kept biting sporadically for everyone the rest of the day, and the same was repeated the following day. Just goes to show that sometimes the ZVT tech can really ignite an old burned-out nugget patch. Much fun was had by all, and it really made up for such a short two-day detecting trip. Pictured below are my finds, including the 40 gram chunk, a couple nuggets at over 8 grams, and all the small bits, with a total combined weight of over 66 grams.

      Four used ones advertised on The Classifieds in the last couple days, one sold already. Seems like Gerry’s circle of people... you know something the rest of us do not know Gerry?
