3 new coils to be released for Minelab SDC 2300

Gidday All,

Coiltek have this morning announced the release of three new coils for the SDC 2300.
New lower shaft as part of the adapter kit.

10x5” Elliptical ($330)
11” Round ($375)
14x9” Elliptica ($375)

Release date is 4th April.

Going to make an already deadly machine even better !
Simplicity of use over heavily mineralised ground plus a 14x9 for ground coverage = happy days !    

Rick

Exciting times ahead, that's for sure Rick.

Cheers Kon.

Was contemplating selling mine but not anymore.

These look good To use a Minelab phrase.."They'll open up the goldfields again".... Well the old mullock heaps at least

Any testing videos been done?

Thankyou Rick

Been a long time waiting for this news.
Woo hoo exciting times ahead

A good point made on another forum.
The advantage of these new coils will only be for those that own a SDC only, as fitting a larger coil will not bring it up to the performance of a GPX or GPZ. The SDC is a 'fly poop' detector, especially good on tiny targets, so any advantage will only be in coverage, not extra depth, as anyone who has used various machines will know. For instance, a GPX fitted with an 8" coil will give better depth on slightly larger targets than an SDC with its standard coil. Fitting an 11" coil to an SDC will not make it perform as well as a GPX with the same sized coil, especially if the GPX is running a flat or spiral wound coil.
Testing will soon bear this out.

True Reg. The MPF PI tech employed in the SDC isn't about depth but the very fast switching between tx & rx is ideal for pinging those small, shallow bits other detectors can miss.
I don't see the new coils giving huge improvements in depth in most conditions but the ground coverage of the larger coils will be their big positive if sensitivity is maintained (although the depth on some gold has surprised me at times with the SDC so in some areas a larger coil may get a good improvement?) + some will like the Joey coil for poking into tight spots. Good for those who only use a SDC but a bit obsolete for anyone that also has a GPX.

G’day Reg,

So going by what you have stated above, the SDC 2300 will not detect any deeper, when fitting a bigger coil to it.   I think the law of Physics would tend to differ from your statement above.  

Here’s a nice specie that Jen detected last year in WA.  It was 15” deep and 4/5” inside hard cap rock using her SDC 2300 with its standard 8” coil.

Wow! Now it’s beautiful... prickly. But oh so nice now it’s out of its host rock  

There was some really fine gold as well. That I didn’t place on these scales
All up it weighed 63.3 grams.

That was a beauty Jen

Fellas, only my opinion here, but all of you tend to make good valid points/sense. Coiltek has produced a variety of different size coils for the SDC, each coil no doubt, designed for a specific purpose in mind. The technology might not be in leaps & bounds above what the standard 8 inch SDC coil is currently capable of, but I have no doubt these new range of coils for the SDC have been designed with improvements in mind & not the other way round. Of course proof will always be in the pudding & testing over time will tell. Shame that Coiltek & or Nugget Finder (2 of our leading, world wide coil manufacturers, for what ever the reasons) weren't allowed or given the rights to experiment & come up with something similar for the GPZ 7000.
One things for certain, I'v got to give Coiltek & Nugget Finder credit, for producing & introducing something new on the market for the various makes/types of detector we currently have in use today, or we were all in danger of going "Stale Mate, Kaput, End of the road"  

Cheers Kon.

Mike the point that I was making is that the SDC fitted with larger coils will not outperform either the GPX or the GPZ. Jen's specimen could most likely have been detected with either of the other detectors. I have used an SDC, and have seen it tested against GPZ and GPX. Tiny gold is its forte, but it runs out of puff against its big brothers on bigger gold at depth.

Being a long time SDC user I'm keen to see some solid comparisons done with these new coils vs the standard, but I agree with Kon these coils are a positive move forward.
Just that extra motivation to get people out there with something new and looking is a massive thing, cos lets face it you find more gold out on the diggings than on the lounge.
And if nothing else this give guys with SDC's out of warranty an easy way to stiffen up that floppy head issues later on in life!  

Good point Hoffs Gold. That knuckle arrangement is very awkward. Must have been designed by the tea lady.

At the Wedderburn Token Hunt , Coiltek Gold Centre had one on display with the new 14 x 9 on it .

Having no experience with the SDC , I thought it was well balanced , possibly a bit heavy ..?

Hi all,

I have actually pre-ordered the 14x9. I love everything about my SDC with the exception of that silly rear knuckle arrangement. I have never folded mine up since new and it is always fully extended (no pun intended). I love the idea of the elliptical coil as my go to area is in heavy bush and the 14x9 evo works for me on my 4500. I do want some depth advantage over the standard 8 inch and the 10x5 coil, so we shall wait and see if the knockers are right or wrong.

Will it go any deeper?? we wont know till they come out, but here on the NSW far south coast most gold I find is at an average depth and not that deep (3 - 7 inches), depth is not an issue but I do like the extra coverage of a 14x9 and using the toe of an elliptical coil over a round coil in vegetated areas . My mate has pre-ordered the 11 inch coil so it will be interesting to do some testing comparison on our gold fields with a standard SDC before making comments good or bad.

I note that these new coils are 'water resistant'. So any water proofing of the SDC down to 3 metres could be compromised. This doesn't effect me but others might need to look at that. I like the fact that companies like Coiltek and NF are continually bringing out new products for our machines, good on them. Lets just wait and see how they go.

Your not going to believe it, but i dreamt that there was a new coil for the SDC . I was hoping they would bring out a bigger coil, like the 14" x 9", hopefully it doesn't lose any of its power by using up more battery power, (like my Gold Bug 2's 14' elliptical' did,) and it will go deeper than the 8" or i would think it useless. I don't subscribe to the "cover more ground theory, I want more depth!" 3 extra inches will do it for me. I'm never in a rush, just take my time, it's much more pleasant and much more thorough.

Who are the brave souls who will take the first plunge and buy it and test it and hopefully tell the rest of us how it performs against the 8 inch coil?
By the way, it's not the money stopping me from being one of the first to try it, $400 is reasonable, rather its a case of "once bitten twice shy.
( The 19" GPZ 7000 coil)....... remember that lemon?

Heading up to my sister's in Bendigo on April 6..thought i'd check out the big Prospecting show at the showgrounds

Just wondering if Miners Den will have the new Coiltek SDC coils for sale at the show? There's nothing about them at all on their website

Hello Miners Den?? Anyone home??

Extra ground coverage by the 14 x 9 will not open the goldfields again unless it has extra depth. If it only goes down to the same level as the 8 inch coil then what have you gained.... nuthin!

Hi Sharkbait - yes they will be there and have them for sale. more info to come from them soon.

I am coming over for the event also and will be on the Miners Den stall to chat to those who wish to about all things Coiltek so if you are going to the event in Bendigo make sure you say hi!
As it is the weekend after the on sale date I am sure there will be lots to talk about

In the meantime you are welcome to ask me questions either by calling us at Coiltek or emailing us.

Cheers, Trevor.

Thanks for the info Trevor,will definitely pop over and say g'day when i'm there

Reg, extra coverage or extra depth?
It sounds obvious - if you could elaborate. Actually thinking about the 14 x 9 New SDC coil, any thoughts?

Surely , one of the 3 new coils will have more depth than the original 8 inch coil.

It is open to debate whether increasing coil size will increase depth in any situation. Timings have an important role to play, as does the type of winding. It has been interesting over the years to witness testing of various machines and coils.
Flat, or spiral wound coils are an example. These coils seem to give a more sensitive response in relatively shallow situations, but are more effected by mineralization and therefore lose some advantage when used on deeper highly mineralized ground, where a bundle wound coil will be less effected and be easier to make out a signal among the ground noises. In this situation a double D coil may actually be more effective.
Having tested many different coils, both production and home built experimental, I have often been surprised at results that have been unexpected, unpredicted, and at times contrary to claims, so I await trials of these new coils at a test site, which will give us a better idea of whether extra depth is achieved.

G’day Reg,

I agree with your point above and I wasn’t saying that the SDC would outperform the GPX/GPZ’s.  I do believe that the new larger coils should have a better depth advantage over the standard 8” coil on larger targets.  
Just my opinion and as you said only time will tell.    

Cheers.

Mike.

Thanks Matt

Hi guys, just wondering if these new coils are flat wound or bundle? Also can we get them with the curly coil which we can thread up the centre of the shaft?
