Yes, this is the same detector pictured here & in all the videos hyperlinked below.

 

WHITES TDI Pulse Scan Metal Detector

The regular retail price of $1,599. This is just about 18 months old and in like-new condition. Great depth! Professional-level ground-balancing, pulse induction detection. Unlike any other metal detector on the market today, the TDI is capable of remarkable depth and extreme sensitivity in the worst grounds. This is a great deal for some lucky person.  This is an American made product manufactured in Sweet Home, OR.  Their customer service is 2nd to none in the metal detecting business. In my opinion, the only other metal detector to best the performance of the TDI is the Minelab 5000, but, it will cost you over $5,000!

If you live in hot mineralized soil, this is the detector for you.  The gold nuggets shown are NOT included!

Features include:

*Full-control Ground Balance: Quickly balance out the iron mineralization of hot rocks, black sand, and other tough grounds.
 

 
*Adjustable Pulse Delay: Settings from 10 ms (best for finding gold nuggets) to 25 ms (for relic, coin and beach hunting).

 
*Variable Audio Select: With Ground Balance "ON".

 
*3-Way Target Conductivity Selector:
Allows variable audio to hear either only low conductive targets like most gold nuggets, or high-conductive targets like silver coins and large relics, or both. This unique ability aids in identifying trash, too.

 
*Threshold Control: Accurately adjust the audio to hear the smaller, deeper signals.

 
*Frequency Control: Adjusts for hunting near power lines, microwave or other environmental interference.

 
 
*Battery Life L.E.D. lights.: L.E.D. lights to indicate battery life.
*Waterproof 12" spider search coil: Other accessory coils available. Most Mono Nuggetfinder coils will work w/this detector.

 
*Two powerful 14.4 Volt Lithium-Ion Rechargeable Battery Packs and Charger & manual included.

TDI metal detector

One should keep in mind that the TDI is not for everyone and it does take time to learn. One can't expect to go out in their back yard, spend an hour or two and know how to work it. It simply doesn't work that way. There is a learning curve that has to be overcome, plus a person should learn just what each control is doing and why it is adjusted. This isn't hard, but does take time to do. Without such knowledge it is very difficult to know just what to do if things are not going as planned.

One more note, I need to check just how the elliptical coil works in all modes and under all conditions. I suspect the elliptical coil will react a little differently and may alter just how the signals sound. The only way I will know for sure is to try it when mine gets here.

The TDI works great for coins. I have personally found over 100 older coins with mine in a park in town that has been beat to death by other detector owners. The discrimination works extremely well once you know how to set it up. In fact, I normally will not dig any trash at all during my coin hunting outings. BTW, set the detector up for coins and then hunt the Rich Hill area for gold bigger 1/4 oz or bigger and you can ignore, yes, ignore all iron including tin cans. Actually, I am not sure just how small of gold it will find while doing that, but I do know that 1/4 oz nuggets and larger will be detected. I have personally walked through the trashiest part of the ghost town Octave and picked out several non ferrous items including one old coin while basically recognizing and/or ignoring the iron junk including the cans and pieces of cans. Large cans do require the coil be raised to fully test the disc feature, but generally, most of the junk is simply ignored and produces no signal.

Then, if you want to hunt small gold, you can set the detector to ignore most ferrous junk and hunt away. Much of the ferrous junk will again be ignored. Small pieces of cans will be detected, but using a couple of tricks and one can determine that type of junk with very high reliablility so one can just about walk by most of that junk also.

Then of course, the TDI can be set to hunt all sizes gold at the same time and still able to recognize much of the iron junk. So, in simple terms, the TDI works great for nuggets and really does well for relics. Now, that combination is hard to beat when you think that the TDI doesn't suffer from electrical noise anywhere like some other PI's do.

You mentioned one should buy a ML, well that is fine, they do work well in most places. Try working under power lines and you may have a problem. There are also places where the emi noises makes things extremely difficult to overcome.

So far, I have not had any of those problems with the TDI. The design is such that it minimizes such problems. Yes, the TDI does have less overall sensitivity and as such the reduced sensitivity allows it to be used about everywhere.

Oh yeah, I do have an SD, but considering the TDI weighs far less, gets about the same depth on smaller gold, the type we find here in the US, plus allows me to ignore most ferrous junk, I prefer to use the TDI.

Now, I doubt you have used one, but that is fine. There are a lot of people who will not want to use one let alone own one. However, before condemning a detector, you really should spend some time with it and find out what it can do. No, it will not compete directly with the 4500, but it holds its own against some of the other models. Now, anyone who tries to compare the $1500 TDI to a $5000 GPX is not even using common sense.

The trick to using the TDI is knowing how to set it up. It does have some features that allow for a wide range of different hunting conditions, so it can be set up to look bad if one wants to try hard enough. BTW, with a tweak or two that takes less than 5 minutes to do and that includes taking the unit apart and the original 200 TDI's built can be adjusted to detect gold too difficult for even the higher priced 4500's to detect. I know this is true because I have done it.

As I said, the TDI is extremely versatile and can be adjusted to do a lot of different things, some of which conflict with nugget hunting. As an example, a good PI will also detect small foil just like it is a nugget. Now, that can be a problem when coin hunting, so with a simple adjustment, the foil can be ignored. Make this same adjustment when nugget hunting and yes, you will ignore small gold too. Fortunately, the TDI was built to be used by someone with a little common sense and as such, such people won't make the wrong adjustments when gold hunting.

The common sense is required and some knowledge of the controls are required to take advantage of the abilities of the TDI to be able to recognize most ferrous junk. So, it does take a while to fully learn the detector so you can appreciate just what the detector can do.

So, the TDI is far more versatile than a basic PI, but it is not for everyone. Common sense, a little patience and the willingness to learn are the requirements to maximize the features of the TDI. Obviously, there are people who want more of a turn on and go detector and could care less about the ability to discriminate junk or think they will miss something.

Keep in mind, there is nothing out there that acts the same or uses the same techniques so it is something new to learn. The TDI has the ability to distinguish ferrous junk even when using a mono coil as well as the DD type.

Just my two cents on the issue.
