SDC 2300 Limits


Rege-PA

Recommended Posts

We all know that the SDC 2300 has proven itself to be fantastic on small gold and people seem to get the idea that it is a very shallow machine and not too useful for hunting nuggets at depth. I realize it is not a GPZ or a GPX but can anyone give me an idea of just how deep this machine can go on nuggets above a gram and into the bigger stuff. I guess what I`m asking is for some examples of dug targets. Is this machine an overall detector or is it just for shallow small stuff?

Hi Rege

This is a machine never to be underestimated.Its not so much the depth in comparison but the ability to fine certain types of gold at good depth where other machine fail miserably.We have found it particularly good on specimen vein and leaf gold mainly where there is no obvious solid sections in the gold.

It is also proven on small gold at depth or gold too small for the bigger PI's.

Depth on most good solid nuggets of the 1-2gram is limited around 8-10" from our experience but we have picked up many small specimens at 6-8".It will still go 1-2ft on large iron type targets but obviously not designed with this in mind.I guess it forms part of a tool kit in conjunction with the bigger Pi's.

The SDC "limited depth" thing is simply because it has an 8" hardwired coil. However, that coil should punch up to between one and two feet depending on the size of the target. Larger target equals more depth. The SDC should hit a 1/4 ounce U.S. nickel size gold nugget at about a foot.  Don't expect anything but a fairly large size nugget (or beer can) in excess of a foot.

What deutran says there is spot on.  The 2300 shines on certain types of gold and leaves a GPX for dead.  This piece I got a few months ago with the 7000 at about 5", but the 2300 can get it at about 6 or 7 inches and a 5000 with the new flat wound coil can get it at 2" max. But for going for solid bits of gold I would use a 5000 over a 2300 all day every day.    The big thing about the 2300 is you`ll find gold with it just about every time you use it. Dave

I've dug several bits of larger lead at about 10-11 inches. On the beach in Salt 2 I've dug aussie $1 coins at 12 inches. 

This bigger bit went 3.57g and was about 10 inches.

I appreciate all the great feed back,  I have a customer who was skeptical of the SDC 2300 ability to find deeper gold,  I think now he will consider it for his first gold detector.

Thanks for all the great examples, only wish some of them were mine! :biggrin:

I've found the deeper targets are barely a pull in the threshold, and some of the responses are quite wide, so you need to do a slow wide sweep of the coil in order to hear the full rise and fall (or the opposite) of the signal. With a short narrow sweep, the target can be invisible.

      Nugget Hunting a Hydraulic Pit 
      Me and Gary  @Two Toes  head deep into the Sierra's in search of those elusive Gold Nuggets the Old timers missed.
      Yes I include Gary in with the Old Timers as he has Detected this spot before. Nugget Hunting in a Hydraulic pit isn't the easiest thing to do but it's one of the funnest and most rewarding ways of finding Gold.
      On this adventure we take three different Metal Detectors The Minelab SDC 2300, White's TDI, and a White's Gold Master V-Sat this allows us to use both Pulse Induction and VLF technologies in our search for Gold and Treasures.
      Watch as we pull those Gold Nuggets the old timers missed over a hundred years ago out of the ground !!!!!
      Gary finds a old Lead soldered painted Can with Gold inside what did the Old timers us it for ? I find Six musket balls encased in rotting wood how long have those been there ?
      Plus Many many old square Nails !!!!!
      Thanks for watching I hope you enjoyed the adventure we sure had fun finding all the cool stuff and wondering what and how they used it.

      I am in the market for a used SDC 2300 and wanted to know if there have been any software/firmware or hardware updates since the first introduction in 2014?
      Are there any pros/cons of buying an older machine lets say 5 years old vs a 1 year old machine?
      Are the supplied oem headphones satisfactory or is it better to invest in better headphones?
      Is the Lithium Battery upgrade a good investment and does it come with a charger?
      Thanks in advance

      I haven't seen very much conversation about the comparison between these two detectors now that the GPX 6000 is creeping into the SDC 2300's territory.  So far, the GPX gets both smaller and deeper gold.  Has anyone other observations?

      Hi there,
      Looking at getting another detector for the Golden Triangle in Australia. Have a vlf but looking at either a new sdc2300 or a 2nd hand gpx4500 for marginally cheaper. Which one would better to learn PI with, and which one performs better?
      Cheers

      A new video has popped up comparing various nuggets on the SDC, GPX 5000 and GPX 6000. 
      Looks like they're in pretty bad soil judging by the depths they can get the nuggets at with all of the detectors.
      They only use the DD on the GPX 6000 for some reason.

      Finding Gold Nuggets with the Minelab SDC 2300 
      Can I beat  @Two Toes  with his own Metal Detector ? We head back to finish off a few spots we left from our last trip out. Gary found some good gravel so he decided to run it though his Sluice box while I was happy to use his Minelab SDC 2300 while he was busy sluicing !!!!
      Those targets that we left sure paid off !!! Nothing like hearing a good sounding target sitting on bedrock .
