Hello all.
I have been using the 11" mono commander coil for around 6 months with my 5000.
i thought the depth was pretty ordinary so i bought a 14" round mono coiltek last week.
I'm not sure if the depth is better but its just a little heavy for me to use it all day.
I was in a new spot over the weekend and used the 14" until i got a little tired so i wacked on the 11" and within 15 min i got a deep toned target.
I managed to score a 1.6 gram flat nugget at 1 foot deep.
The ground was pretty much hard clay/dirt for almost a foot, then i had to hack away into quartz to get to the nugget which was around 1 inch in.
Has anyone used the 14" round mono and gotten deep targets?
Would anyone agree that the 11" has the same depth as the 14" coiltek?
Thanks March

14" will go deeper. you probably just didn't waive the coil over any targets.

some people i speak to about detecting at Clermont favor the larger coils if and when you can get them to the ground as the larger coils go deeper and pick up the nuggets other people have missed using the smaller ones.

i can only compare with junk targets. but on a mullock heap that i went over with an 11" DD coil i did not pick up any targets. i changed to a 18" DD and picked up targets i missed with the smaller coil.. (this was on my old GP Extreme)

The 14" will go deeper but you will have to find ground that is deep to get a depth advantage over the 11", otherwise the only advantage the 14" has got over the 11" in shallow spots is covering more ground.
Get a hipstick if you are finding the 14" heavy.

One other thing that I never see mentioned when it comes to coils is that we get used to a certain coil and get confident with it as we have found gold, stick on another coil don't find anything and go back to the old one. Coiltek gave me 2 coils around 10 years ago when they were the top of the line coils, (long story why for free) they were the 14" round mono and DD. I have seen over 200ozs pulled from a single hole 2 foot deep with possibly 30 or more pieces with a 2100 with a 14" mono!!! I HAVE NEVER FOUND 1 PIECE with either coil!! Embarassed Embarassed They are good coils I just didn't get confident with them. I still have them and do occasionally use them and probably will more when I get out Rolling Eyes

I predominantly used the 10" elliptical "Joey" coil, I then got the 3500 and started to use the 11" DD and a home made coil, found nuggets with both. Another wierd story to do with coils is I have an old 24" Round mono NF coil. I had chained a patch I got 2 pieces at around 4-6gms each with 3 coils including the joey and never found another piece. I was then informed about a few deep ones being found around 20 meters from where I was so on went the 24" NF. I got a small signal, moved all the quartz away and got a better signal scraped the ground with my foot and better again, after about an inch I had moved the target. 10 minutes later i was holding a 0.02gm nugget (if you can call it that! Shocked ) in my hand. What is so amazing is it was less than 1 foot from where I dug a 4 grammer and would have positively gone over with the other coils, all that didn't hear it yet this mammoth of a coil did Suspect I have been totally amazed about that since it happened. Even with the nugget out the other coils had to scrape it to get a response. That was with my 3500.

Another totally weird story for those with a 4500, my mate did some tests on his first trip (which BTW he paid for his 45' and this was just last year), with a few coils, a coiltek 18DD, 17 x 9? & 24" Elliptical monos and an old 2000 dustbing lid 18" mono, you probably already guessed which coil worked best, THE OLD DUSTBIN LID!!! He purchased the old 2100 Kevlar 18" mono and did some more tests and found out of all it was the best... I was told by a reputable nameless coil maker that the 4500 work better with coils designed for SD's "Q" level...

Anyway just some thoughts and info that throws all sorts of coals into the fire!!! Twisted Evil Twisted Evil

Interesting topic. I agree with Ismael the old SD coils are still ok on the GPX's. I have used my old 11 mono ( that came with my 2100 when it was new ) on my 5000 and it was as senitive to small nuggets as the new commander 11 mono , and seemed less suseptable to bumps and emi ! I have been meaning to give the old 18 kevlar a run on the 5000 as well , so will post my findings .
I have been less than impressed with some of the late aftermarket coils .
My prefered coil on the 5000 for gridding is the 15 x 12 Commander mono. ( brilliant coil , but heavy ! )
-- For wandering and patchfinding, an old SL NF mono.

Thanks guys for your thoughts, i must say, i really should give the 14" more of a go.

I agree with you ismael, i'm so used to the 11" and i'm scared of changing, thinking i'm missing out!
In saying that, th 14" coiltek mono is brilliant for thrashing around on the ground. Bit like the 11" commander, you can really rub it over the twigs,rock and leaves and it still retains the constant tone.
Let you know how i go with it....Thanks March

Hi march, Next time you go out and find a target spend a bit of time experimenting BEFORE you start to dig the target. When we were learning and also when we purchased different coils we always spent some time trying different settings and diferent coils on a target before we dug it. (we were always lucky as was never much trash around where we detected). By trying diferent coils and changing settings on your machine (we use 4500) you get to hear how the signal may sound diferent or more clear and also get a jist of how the coils are diferent from each other. I still love the origonal 11" mono that came with machine but do use a 18" nuggetfinder advantage a lot to and they are both very diferent coils and settings on the machine are diferent for each diferent coil that we use. A bit of time spentexperimenting more than pays for lost time detecting and will reward you many more times over.
The other thing, if you are tiring from the larger coil you will find the hip stick is a marvelous and well worh while purchase (we would not manage with out one)
Hope this is of some help to you.
Keep swinging, travelergold
