TDI

[Adrian SS]

HI,
Is anybody out there using the TDI; It seems to be a while since I read a new post re this detector.
I am wondering how it handles heavy iron mineralisation and saltwater beach conditions.
I have watched a video demo of this machine but the ground conditions were pretty tame and did not give me any clue to how well TDI performs in bad ground.?
Cheers,
Jackinthebx.

Dear jackinthebox;
Since I use PI detectors almost exclusively, I've been following the development of the Whites' TDI with some interest. From early reports, it seems that the TDI is able to handle heavy mineralization better than the Minelab PI detectors, although at the cost of some depth, however there is more to the story than just this, my friend.

It seems that Whites' wanted to build a PI detector for both the seasoned pro and the rank amateur alike and from initial field reports it would seem that they've accomplished that goal. The TDI was engineered with input from Eric Foster, who is the king of PI technology, to be quiet in heavy mineralization, salty environments and around heavy electro-magnetic interference, such as power lines.

In this regard the TDI supposedly outperforms the Minelab PI units, however a Minelab detectorist can also respond to these conditions by using a different coil or adjusting the settings on the detector to minimize these sources of interference, again at the cost of some depth.

I also like the fact that Whites built the TDI with a coil aftermarket already firmly in place. According to Eric Foster, the TDI is able to use all stock Minelab, Coiltek and Nuggetfinder PI mono coils! Between the three major brands, there are over 30 coils already on the market to choose from!

Also, the TDI can supposedly use all existing Minelab, Coiltek and Nuggetfinder DD coils, however the TDI was designed for mono coils, therefore using a DD wound coil has no advantage over mono coils when used on the TDI. Again, this is according to Eric Foster.

Since I already have two Minelab PI detectors I am not in the market for a new one at this time, however I am seriously considering the TDI for my next detector!

Thanks for your input re the TDI.
I have been metal detecting for the past 45 years and have owned 27 different detectors and have built a few including PIs, I currently have 19 detectors. I spend most of my time detecting saltwater beaches now as opposed to 15 years in the Aussie goldfields; Digging the beaches is a lot easier on my back.
The TDI sounded good when first released, but for one reason or another it doesn't seem to be attracting much interest here.
From what I have read it does seem to have a bit of a learning curve. I guess as more people learn how to use it correctly and bring out its true ability it will become more popular over here.
Thank you for your interesting comments regarding this detector, you answered most of the questions I had in mind.
