A Summary Of My Feelings About The Minelab SDC 2300


Recommended Posts

I responded to a question about the SDC 2300 on another forum and my answer pretty much summed up how I feel about the detector. So I decided to post it here also.

Originally Posted by DDancer: Thanks for that input Steve. If you don't mind I'd like to also ask you how you feel about its ground balance, threshold stability and performance when other PI detectors are in the area. Any problems with emi interference from aircraft or metal structures? The SD series had a lot of difficulty in the area of emi and GB with the 2200 was never really stellar in my opinion.

The ground balance is almost a non-issue. In many areas the SDC 2300 simply ignores the ground right out of the box and there is no ground balance procedure. In more mineralized ground, holding the ground balance button causes a quick ground balance to occur. The SDC 2300 is always automatically ground tracking at a medium-slow rate to maintain the best possible balance, so it is impossible for a novice operator to mess it up. I had no issues with it tracking out targets.

I did encounter hot rocks the SDC would not balance out, the very same types my GPX 5000 would not balance out. Overall the SDC handles ground as well if not better than the GPX because it is running a variation of the fine gold timing and the small coil "sees" less ground than the stock coil on the GPX 5000 therefore there is less ground for it to balance out.

I can get my GPX 5000 to make a threshold that is perfect with no waver. The SDC 2300 has a less stable threshold more reminiscent of other SD series detectors at higher sensitivity settings. It is pretty stable at the stock "2" sensitivity setting but still not as solid as my GPX.

The SDC 2300 is quite a bit more EMI resistant than the GPX 5000 and plays well with other detectors as long as reasonable spacing is kept. When my brother fired up the SD2200v2 I could get within about 50 feet of him unless he ran a larger coil, then I needed a bit more space.

The bottom line is the SDC 2300 is perhaps the most user friendly nugget detector you can buy. Anyone can run it. It really is normally a turn on and go detector. The only option normally to consider is the sensitivity setting, which gives a balance between a bit more depth but more threshold noise. We were in mild ground and I could run it maxed out but that did make for a less stable threshold. Once you find the sensitivity setting you like in an area you just leave it alone; the ground balance setting is retained when the detector is turned off. So for me operating the SDC 2300 boiled down to turning it on or turning it off. Batteries lasted a good seven hours plus. It seemed just right for most days, never quite running dead by the end if the day except for rare occasions.

If I have to complain about the unit I could complain about the armrest folding up every time I pull my arm out and the lack of volume control. The headphones I received are wired on the left and the cord runs across your chest. You either wear the headphones backwards, or in my case run the cord behind my back. I need a headphone adapter to run optional phones with volume controls. But these really are minor niggles. The waterproof, compact folding design is extremely compelling and easily offsets these minor complaints.

The SDC 2300 except for the cost is a perfect detector for many more casual nugget hunters who would never, ever learn what all the settings on a GPX 5000 do. It is far easier to operate in bad ground than a VLF. I can hand one to anybody, tell them to turn it on, keep the coil on the ground, and dig everything that goes beep. If it were not for the high price I would flat out just tell everyone to go buy one. It is practically impossible to be unhappy with the SDC 2300.

Picture below of SDC and some other small nuggets I found with it I have not posted previously. The little black rock specimen in particular is an example of the type of gold the GPX has issues with and in fact this little piece came from an area I had previously hit with the GPX. There is but little gold mixed in with the rock in the tiny specimen.

      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?

      Hi!
      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?
