Outstanding explanation of these coils Hunter. Along with the linked videos there's not much left to ask!! Great series and shared with my groups.
Thanks Jeff I appreciate the share!
Great information. Thank you for all you do to help the community. You Rock!
My pleasure! Thanks for watching and commenting!
You are always dropping such great info. Thanks THGT!
Thanks guys...appreciate that!
Thanks for the info John. I do like these video because there may be something I forgot so I look to these videos to refresh my memory
My pleasure...thanks for watching! I tend to refresh my memory as often as I can. It does get stale as I age. :)
Great info thank you. I didn't think those pics of how the field around the was were correct now I know for sure.
My pleasure Papa! Glad to be of service.
Solid info, Hunter - thanks for the great info!
My pleasure Jack!
I have yet begun my adventures with my detector, but so far I am quite excited! (My first is a basic Costway)
Thank you for the vids, hoping you plan to make more? Maybe even so far as "Metal Detecting 102" maybe?
I keep telling myself I want to, but never get around to them. Appreciate you watching and enjoying.
Hi John , good info once more my friend , they both have a lot to offer but as you say it alldepends where you are going to use them , nice one mate ATB GL & HH Rob .
Thanks Robbie. Hope you are well my friend. Love to have both in the toolbox...if the detector accepts both of course! ATB and HH.
I use em both Hunter!
Another informative video.... Bravo!.... Well done
Thank you Carey!
I just picked up a concentric for my vaquero, can't wait to see what i was missing
You will for sure find stuff the DD could not...and vice versa. Best of luck with it for sure!
Hi so what its beast on beach salty water etc .Or what metal detector ?
Hopping for concentric for nox !... great video
Thank you! Unfortunately, I do not see that happening. Who knows though.
Hunters right with the NOX..........any detector that has a gold setting will 99% of the time will be a DD coil, simply because of high mineralisation areas where most gold is found.
thank john
Thanks, I have always used a DD coil. Never considered a concentric coil
I prefer a DD for sure. But concentrics have their place. Thanks for watching!
Very good, thanks!
Thank you!
HOW TO adapt mono coil to DD metal detector ?
Excellent tutorial video. You give a great overview /analysis on these two respective search coil platforms; their assets and their down-sides, as well as dispelling the myths surrounding the field/shape of ground penetration between Concentric and DD coils. Very interesting, extremely well presented, and of significance to both newcomers and seasoned detectorists alike. Bang on! ATB, & Take Care.
Thanks Tim I really appreciate the compliments. Glad to be of service and hope people enjoy them as much as you. ATB my friend.
@@thehuntergt You are more than welcome. You are worthy of all compliments for the work you put into All your presentations. Credit where credit is due, I say. If there are people that honestly don't enjoy your work, then in my opinion they'd probably be better off train spotting, or watching paint dry! Top Man.
How about performance between a DD coil Versus a Mono Coil in high mineral Arizona gold field-ground ?
My opinion is a DD always for heavy minerals.
good info on a good topic !
Thank you Cys!
So is the 12 in spider coil the same as 12 dual field coil by whites are they both concentric?
Both are concentric coils as far as I can tell.
Great information!
Glad you think so!
Great explanations, but how wires are connected in both types?
That is a bit too complicated for this 101 video. Perhaps in a 202 video.
Some great info there on those coil heads

Excellent information and yes I was a believer in the cone and knife blade diagrams. I was actually just spreading the propaganda two days ago lol. Thanks for sharing and take care.
Clayton County History Hound hi Clayton
Thanks! And no worries CC. When the companies like Garrett are putting images like that on some of their boxes...people take it as truth.
Sir can I ask you the schematic diagram of dd metal detector??
Go check out www.geotech1.com/forums/forum.php
I don't know if anyone else has considered this but my pinpointing function seems more accurate with the concentric coil.
Correct. The inner circle being so small does a much better job at showing direct center compared to a DD which can drift much more on dead center.
So how do I make my own coil
Guys do it in their garages for PI and BFO machines...so it is possible. I'm leaving it to the experts myself. Every home job was maybe 50% depth of a stock coil.
Is a concentric coil the same thing as mono coil? Thanks!
A mono coil only has a single loop. Concentric is two loops...one inside of the other.
A true mono coil is only used in pulse induction metal detectors.
Beat frequency oscillation metal detectors can appear to have a single coil but actually have a second smaller one in the control box.
Very low frequency metal detectors require two coils in close proximity to function.
Which would you use on a beach.
Concentric as beaches are full of bottle caps and trash. I would prefer the stronger ID and disc capabilities.
Normally I use the 15 inch DD coil for the beach as. A larger DD coils cover more ground. My xterra 705 detector can use both coils.
@@JACOB1556 Yes valid point on ground coverage!
@@JACOB1556 how do like that x-terra 705 I've been watching ebay to get a deal on one.
@@nts323 works very well very good at pin pointing with the stock concentric coil. it also works good at the beach but not as well as the more expensive Nox 800. I have 3 coils and the stock concentric one is my favourite as I use that more often.
Please Help us with making the coils by ourselves sir
Specially a DD coil
My advice is to just buy a coil. Homemade coils are a waste of time and money when trying to beat a factory coil. If you are doing it for "fun" only...that is different I suppose.
Nice video
Thank you!
Good👍👍👍👍👍
The music is pretty cool but you cut the music right after the beat drop.☹
Not much logic in doing it before the drop is there?
But i was enjoying the beat lol.
I really like the 101 vids though. I'd like to see more on gain and threshold. I thought you had one but don't see it.
@@poppacherrie Threshold will be my next 101 video...most likely 2 more coming up then call it a wrap for the series.
Whoop!
de doo....
@@thehuntergt Used to hate those. The old Honda Elsinores didn't handle them too well. Sail right across 'em now. Gotta love the conventional suspensions.
Every magnetic field geometry is a reciprocating processional hyperboloid
Like...duh.
