Whites 7.5″x12″ TDI High Q Dual Field Coil Available Separately


Recommended Posts

This coil is being advertised at quite a few dealers now for $179.95. Which is great, available now for existing TDI owners. I had to chuckle though. They all are advertising it as “Whites 7.5″ x 12″ TDI HI-Q Dual Field Coil for MX Series Metal Detector

Makes me wonder sometimes if I am the only one that notices stuff like this.

Nope...LOL I noticed it weeks ago, and almost contacted the seller to tell them, and then I decided you can't fix stupid, and let it go...LOL

Hey Guys,  That's what I got with the TDI SL. 

Seems like the hot spot is dead center, under the shaft.  Not under the sticker. 

Let you know how it performs.  Seems about as sensitive as the 7.5" Round DF.

Take care.

Steve I've just purchased a tdi with the high q coil and it came with the 7.5 field coil which I think is just a duel coil anyway have only been practising with it and I'm finding the smaller coil seems just as good the fact that the duel coil u can use as a pinpointer as well as the high q only picks up in the centre just a thought I'm new to detectors and going out for a few days soon I feel I should get used to the duel small coil to get the hang of it of course will put the high q and have a go as well but watching YouTube videos of ppl trickling the soil on the coil to pick out the gold would be hard using the high q also thinking of getting the 12 inch duel coil for maybe more depth any thoughts you might have appreciated

I wouldn't bother buying the 12DF. You should be covered for depth by the Hi-Q, and the 12DF is a beast to swing for very long, IMHO.

The 7.5” x 12” Hi-Q is a dual field coil with a fancy new name. A large outer coil with a small inner coil. If you use a small test nugget only the small inner coil is reacting. The larger outer coil adds more depth for larger targets.

The 12” round dual field will act the same way. Only the inner coil will respond to small targets, the larger outer coil the larger targets. As a round coil it has a larger total area than the Hi-Q elliptical so will get just a little more depth on large items, but not much, maybe 10%. All my old TDI detectors came with the 12” round and I did not think it was a problem swinging one all day. But overall I don’t think you will see much difference between it and what you have, unless that possible extra inch on large stuff is really important to you.

Thx Steve for your input Im new to detectors and tried the high q again and yes I must of been trying to small of a piece to detect on the outer coil so I think I have all the settings right because I'm going out for a few days to give it a swing since I will mainly be searching in high mineralised ground should I invest in a mono coil I have heard most minelab coiltech coils fit even the whites 7.5 mono aussie addition coil any thoughts on that appreciated also was thinking of the 9 inch coiltech elite coil not to big or the 11 inch coiltech there expensive so would need to know they work on my machine but I guess I probably should see how I go once have had a go with what I have just wanting the best coil for depth for my tdi sl I bought the orange battery pack for the 18650s and have found some good batteries not Chinese that put out around 13 14 volts when fully charged so I'm not going to do any battery mod don't want to void my warranty thx again for your expertise put in a few pics of my homemade skid plate made from a plant pot and some covers to protect it from the elements  cheers

Well, all I can say is that if I got another TDI I would have to get a mono coil to go with it. Either the Sadie or White’s Aussie 7.5” in my case.

99% of all SD, GP, and GPX compatible coils will run on the TDI

Whether they run well or not is another story. The only ones I’m willing to vouch for are White’s made coils for the TDI. Everything else a person is on their own. The links have the details.

Cool thanks again Steve for your suggestions I added a few pics and have edited the post I think I will probably stick with getting the Aussie mono coil for now even though I'm not sure what the difference is from field coil but will research that some more 

Cheers

      Is the main difference between the TDI Pro and SL is gb course and fine adjustments? Is there any power difference between the models? An old friend might be selling his TDI and I believe it is one of the older Pro's and I might snag it.
      Also what 3rd party coils work with them?

      Looking for advice on a small elliptical coil purchase for a TDI Pro. As someone pointed out in the Classified section Serious Detecting is having a clearance sale. Looking at the Coiltek 10 x 5 Joey Mono, and the Whites 7.5 x 12 TDI HI-Q Dual Field. See lots of good reviews for the Joey, but not much is posted on the HI-Q. I guess that initially the HI-Q was only available as part of a TDI-SL package and some were hoping that it would be available separately in the future. It appears that when it became available on its own that it was possibly misleadingly labeled as for MX series detectors, and I was wondering if that is why you don't find much feedback specifically on that coil.
      Any feedback on either or both would be greatly appreciated.
      Thanks

      Speaking of PI detectors.
      Now that Garrett has aquired  White's.
       How about a multi frequency Whites TDI ???
        98 frequencies from the Infinium.
      Added to the Whites TDI with it's incredible ground tracking and ground balance.
       That sounds interesting !

      I have a TDI SL coming in today. I know most people want to detect for small gold. In my bad soil I want to detect silver coins that my CTX3030 can't reach. I'm a long way from the beach and probably long way from gold. That leaves coins and relics.  I've heard that larger coils tend to ignore small trash which sounds good for a coin hunter. I know that if you raise the delay that this helps but with a loss of depth. A 12" dual field and 7.5" dual field are coming with the machine.  What could I get that would be better suited for detecting coins?

      Which do you think will hit deeper on wet sand?  I'd prefer a TDIBH over a DF but I'm budget limited.
