GPX 4500 Coil.

Hi everyone.

As a general all round detecting coil (apart from the commander 11 mono) which size and brand/model of the 12 x 9 or 14 x 9 coils from your knowledge is the best match for the GPX 4500.

Thanks
G.B.

A mate once said everyday I go out takes me one day closer to finding a nugget.

Hi G.B
The 14x9 NFA was an excellent match for the 45.The new Coiltek blitz is getting great reviews as well.The main reason for choosing one of these would be the weight benefit.

hi gb
both those coils you mentioned would be pretty close in performance to the 11" commander. if you are looking to get another coil i would suggest maybe a 14" round

i'm with phoenix 14" N/F round as they go to a nice depth and good on small gold as well, the elip coils are great for pinpointing but don't go as deep. i dug a 4 gram nuggrt the other day it was about a foot deep.

the big one was the nugget


this was the hole

Nice post Stoppsy,great photos.

thanks mate, the signal was nice and loud so i new it was going to be a good size and deep after i took off the first 2" off dirt. the 11" commander coils are a great coil as well but i stick with the N/F to find the first bit then chop and change coils for depth and then go smaller coils for small fine gold.
cheers

Hi GB I found 14-9 coiltek mono worked very well when I was using the 4500 found plenty small bits and the ocational deep slug with it. At the moment using the blitz on my 5000 very sensitive coil.

Both of the coils you mention work well on the 4500, the 14x9 is well suited for the 4500 and very good for small nuggets and also specimen nuggets, the 12x7 is a nice little coil well suited for overgrown areas like you see in spinifex country, also a very useful coil for use in rubbly conditions as well or even on old scrapes and mullock heaps.

As mentioned re the 14" round mono nuggetfinder advantage coil, it is my general use coil, it will get the little bits that the commander 11" mono will get but has the added advantage of better overall depth and ground coverage, it is well suited to the 4500 and I would not hesitate to recommend it based on my own personal experiences with it, both the 14" eliptical and the 14" round coils are really light weight and can be used for long periods of detecting, it will really come down to what your preference is in the coil shape, but which ever way you choose to go you will have a capable coil with either one of them.

G'day Guys.

Am I missing something here? What 12x9 coil are we talking about?

Cheers kon61.

12"x7"NFA?

Yeh,thought so.

Cheers Deutran kon61.

Gday

Yes 12x7 not 12x9 sorry about that, good to see you guys are on the ball though

cheers

Thanks guys for taking the time to respond.

In relation to the 12 x 7 (not 12 x 9 my mistake) I have a 10 x 5 Joey that will probably do close to the same job I hope.

Re: the 14 inch your replies convinced me that's the way to go however at this stage I'm still unsure whether to go round for depth or elliptical for sensitivity.

Could anyone indicate from their knowledge how much difference in depth or sensitivity does one actually lose or gain by choosing the 14" round or 14 x 9 Elliptical mono coil?

Thanks.
G.B.

G'day G.B

On average the 14 round mono will surpass the 14x9 mono coil (in depth) by an average of + or - 20% as nuggets start exceeding the 5 gram+ mark.As targets go bellow the sub gram mark you'll find the reverse will apply in depth.The 14x9 will give a sharper more defined signal on the tinier sub gram gold,at slightly better depth than the 14 round mono.Both monos will attract E.M.I during or in close proximity of thunderstorm activity,less on the 14x9 than the 14 round.

Cheers kon61.

Kon has summed it up nicely, but I would just like to add that from my own use of the NF 14x9 eliptical mono coil I found that it was somewhat twitchy and more responsive to ground noises, and found myself scratching away at sounds that would dissapear when the ground was disturbed, now this of course might be perculiar to the types of ground we detect here in WA, but I have found the NF round 14" mono coil far more stable and less sensitive to the afore mentioned issues, as far as emi goes both coils seemed to cop their fair share on some days and I would find it hard to say for sure which coil was more effected than the other.

As far as depth ability of the 14x9 it is a fairly capable coil, but would not match the ability of the 14" round coil for outright depth and quietness, on targets that were located with the 14x9 by a detecting partner and then checked by me I found that the minelab 11" commander mono could easily have found them as well so the depth is adequate but by no means astounding.

But I still think its a good allround coil and the shape makes it easy to use in tight areas, its light and easily swung all day without a hipstick so its a good coil for trolling with, and will cover most of the requirements for sensitivity, ground coverage and depth, and if you are not a fan of heavy cumbersom coils then it will suit you fine.

Thanks Guys.

Your input was very much appreciated.

In regards to which 14 inch coil, due to the favourable comments on both I haven't been able to choose one or the other as the to buy, so it will probably come down to best deal/value for money on the day of of purchase.

I see Bendigo Gold have some interesting "specials" on their new website..........

Hi guys I think all nugget finder dealers are having a sale going at the moment.

Cheers

Hi all,
It intrigues me, do you check every target before digging with your range and your mates range of coils to establish which coil detects deeper?
Anyone just getting into detecting must be completely baffled with all this?
May I suggest to all of you who are taking up this great hobby, buy a detector you can afford, forget about all the hype about "depth & different coils."
Do your research and "low & slow swings" over known gold producing areas and you will eventually walk over a nugget.
As your confidence & experience develops then you can spend more $$'s on extras for your machine.

Thousands of square kilometres of WA gold bearing top soil is rarely deeper than 350mm, for depth, the Minelab 11" Commander Mono is all you need on the range of machines.
The larger coils only aid covering more ground with each swing.

hi fella's , iam new to this forum and its great too get advice from those that know what they are on about, i have a 5000 iam looking to cover a bit more ground as well with a new coil and wont to buy a nf 14" round , iam i better with a soild or spoke coil? i needsome help on the the two coils please , regards brian.

High Golden Horn,

Both coils preform equally and are exceptional coils mated to the 5000
Some people prefer a solid coil over a spoked coil in bushy or scrubby terrain to aleviate the problem of sticks getting hung up in the spokes.

Weight factor is a concideration also.
The NFA 14" round spoked coil weighs approx 730gr while the NFA 14" round solid coil weighs approx 920gr.

Cheers,

Steve

how you going steve, i have looked the weight diff on the 2 coils and its doing my head in on witch way coil to buy, is it that much of a hassel with sticks pokeing up through the spoke coils? brian

Good thanks GH, just heading out for a swing.

I don't find it a problem at all. The 14" spoked has been probably my main coil for the last couple of years. Weight factor is no problem either, it's something you get used to when you swing regularly.

iam leaning towards the 14 nf spoke for the light weight to swing thats for shore, hey thanks for a bit of advice mate , brian.

I thank all for the advice here as well. I have a 5000 but I am leaning towards the 14" Round NFA.

Is the difference between a 4500 and a 5000 enough to require a different coil??

ERR YES YES YES, The extra 200 gram weight is nothing compared to getting hung up every 5 minutes. Double up on your weetbix and the problem of extra weight will dissappear
My personal favourite, and go to coil is the NFA 14 x 7" solid

shiraz, this is the feedback iam wonting to know, cheers, those who use a soild 14" and those that use spoked 14" nf detecting the g-triangle ? witch of the 2 coils is recommended ? hope some more pro's can give me the run down, again guys thanks for relying, brian.

If your not that experienced I would say the solid over the Spoked. I have been using the Spoked for years and dont see what all the fuss is about.
You may get the occasional small twig stuck in the Coil,but so what. Never had a problem of it getting `caught up`and I detect in amongst the debris under Gum trees quite alot.
Sometimes it can false when hitting sticks,but this sounds completely different to a proper target signal. Even slight pauses in the Threshold(from deep small Gold) sound different than Stick falses.
I think its lazyness that some people dont check the target from different angles;that way you wont miss much.

hey Gus, thanks for the advice m8 ! great to here what other blokes have to say about soild or spoked coils, thx brian

For the last few weeks have been using the 14"NFA and the 14"Coiltek solid round(Brown).The weight difference is insignificant as the solid is light and can be used easily at 45 degrees such as on tailings etc.The solid can be srcubbed giving closer ground contact and I,ve found a slight improvement on picking up small gold.Both coils definitely have significant depth advantage over the 11"mono,the 14"x9" and similar.I've had to bring in the shovel for a number of deep targets mainly large lead and old timers pocket knives found in ground I,ve been over with the smaller coils.All these large targets were at 18"-24"or more.
Until I used the 17"x11" and these 14" monos I don't remember digging these deep targets on a regular basis.The 14"solid is the earlier one from coiltek and is an excellent match to the 5000.There was no sign of falsing in any way and runs quiet.The 14"NFA performed equal or better than any other NFA I,ve tried,no signs of falsing light and a pleasure to use.Both handle EMI well.
There is still the need to run back over the ground with the 14"x9" or 11"mono as more small gold will be found missed by the larger coils.I have experienced this a few times particularly the small species.
These are just my findings and I hope this helps.
Steve
