How to approach making a coil for Infinium

[Eugene52]

4 or 5 pin DIN plugs

benhur,

I would be interested in the schematic as well. I was also told that the Sea Hunter MkII has electronics in the coil also. Didn't know if it was the same, or if you have that one as well.

Has anyone ever found a source (other than Garrett) for the 4 pin connectors for the Infinium and Sea Hunter?

Thanks,

Robert

Here is a Good link for DIN plugs !!
There are a few more posted all over the internet .

Has anyone been able to put together a larger coil for the Infinium? Every time I think about that machine I pull my hair out that Garret was so narrow minded.

Hello to all,
is there any news on the 18" coil? I wold love to hear if anyone's tackled this project.

I would also love to aquire the schematics that was mentioned in this thread.

[GoldenKiwi]

I know members over on the "Infininium Prospector Network" site have been discussing over and over for some time. Aurum Seeker is currently rallying people to send emails to Garrett lobbying for a larger coil, specifically an 18" mono. I have joined in too and have sent my email to Garrett.
I would similarly encourage other users of Infiniums to register interest in a larger coil with Garrett.

I too would love to know if anyone has tackled this as a private project. I haven't yet, but would very much like to. I just don't have an Infinium yet.

I've tried to PM a few people looking for that circuit but had no luck. I suspect someone will need to sacrifice a coil and the required time!

Has anyone tackled it?
Has anyone traced out the front end RX either?

Cheers

Control Box Disassembly

Does anyone know how to remove the cover from the control box?

Also the connectors are made just for Garrett, so if they won't sell
one your only option would be to change the connector on the control
box.

[Rov]

screws maybe located under facia panel decals an also several deep inside the battery compartment to open case.

[Carl-NC]

There's a single screw in the bottom of the battery well. Remove it, and the face slides out. It can take some effort as it has a double o-ring.

[aupro]

Thank you, very much, I had the screw out but didn't want to exert
excessive force untill I new for sure.

Infinium Mono Coil Design

Hi All,

I've been monitoring the forums and it seems that there's not a lot of progress being made on the homebrew Infinium Mono coil front.

I've been looking to find a source for the proprietary coil and headphone connectors as well, but it's looking pretty obvious to me that they are specially made for Garrett.

I've checked out most of the larger connector manufacturers as well as some specialist ones that do mil spec connectors but there's not much out there that even comes close.

I did come across a very similar unit made by an obscure company in China, but this had two male pins on the plug as opposed to one male and on female. In other respects, it looked almost identical. I may have to follow them up with a direct approach.

I only have a standard 10x14 double DD coil at my disposal, so I can't measure the inductance or resistance of the stock 10x14 mono to get a baseline to work with.

I note that Wirechief has measured the resistance to be 77.8 ohms, but to me this seems somewhat high for a PI transmit coil series resistance. The inductance is in the ballpark, so I'd be very interested in any other info that people have collected on the coil design that may give me an idea as to why the R is high.

I'd be interested in whether anyone has seen the inside of one of these coils and knows whether they've used enameled wire, multicore, or Litz etc.

Any schematics would also be greatly appreciated.

Hopefully with a bit of collaboration, we may be able to come up with a design for a larger mono coil.

18 Incher

G/Day Chaps,
I have been reading what everyone has to say re an 18 inch mono for the Infinium, so I thought I would register and put in my two bobs worth.

You cannot take any notice of the resistance and Inductance readings across the Inf coil Plug pins because there is a couple of polarity sensitive components inside the housing that screw the readings up a tad.
My 10 x 14 mono gives 67.4 ohms/77 micro h and 0.9 ohms/186 micro h.

the 8 inch mono gives similar but slightly different readings.

The polarity sensitive readings give around the 430 k ohm mark in one direction and infinity in the oposite direction. Take the readings across the two male pins and the two female pins.

I have not seen a schematic of the coils and plugs but the readings suggest that there are at least two diodes in there. If there are any damping resistors involved I would think that they would be in the control box. As I said, I donot know the cct setup of these coils so I would appreciate any info you blokes can come up with.

If someone has a cct diagram of the mono coils I would realy like to see it if possible.
Cheers,
Adrian SS

Here is how my multimeter sees the 10 x 14 inch infinium mono Coil.

I would not have a clue if this is correct or not, but most probably not.

Larger coil for the infinium

I own an infinium and would like to have one of those 18 inch coils.If anyone makes one that works and would like to make an extra one for a few benjamins I would appreciate that.

Better yet,it would awesome to have one looking like the coiltek 12 by 24 incher.

Garrett seem to be slow on certain aspects of metal detector developments.Kinda like the groundhog battery design.I am not expecting coils like those from them at this point in time.

[Infamy]

Your flogging a dead horse get a TDI. Been there sold the bloody thing. The Garret ownership are too long in the tooth, they need an over haul in their hobby section. Their hobby detectors have gone down hill compared to the competition which is reflected in the lack of support for the Infinium, they never really understood what they had, if they had they would have made larger coils for it.

[adrian ss]

I haven't given up hope yet.

Infinium Coil

I understand and oh yes I will get a TDI eventually as I have whites pi pro dual field and the MXT.I will also be getting the GMT too.

When I get the TDI I want to waterproof it.Really good too as I have lots of stuff to do with it in the water....

Yet I still have the infinium and would like to explore its full potential.I made a post about an inline circuit that allows me to use bigger coils from minelab or coiltek on my infinium.I just need to know if it is technically possible to create such a device? Maybe it could be powered by the detector or have its own batteries.I know it should work but all that amps,gain, resistance voltage pulse rate is not really gelling.

Any suggestions,leads?
