Whites TDI

[Swiper]

Before I part with the small fortune they want for the Whites TDI machine, I'd like to hear some actual experiences from owners, not the factory "spin".
I am primarily interested in revisiting some heavily searched Civil War sites.
Basically, I want to know if this unit performs as advertised for hunting in a non-gold prospecting environment.

For turf/land, it may not be what you're wanting. There are land machines that have as good of depth, and/or better TID. For wet salt mineralized beach, (where you want to hack that, but at the same time want to guess nails and hi/lows) then that would be the niche for the TDI. JMHO

And when you say "re-visiting" sites, it all depends on what machines were used there before, how efficient they were, etc...... I mean, if you take ANY machine out to a site that has been in-efficientally worked before, then YES, you will get more. But from my meager/short experience with the TDI, it is not a machine that will magically open up oodles more depth while magically silencing all non-wanted targets. It's just a spin on existing pulse technology (beach or nugget machines), and you will need a good knowledge of those sounds/feels. It's basically the same pulses (which admittedly have great depth and ground ability) with the addition of ability to knock out nails, tell highs from lows, etc.... There is depth loss the minute you knock out iron though, or play with the disc. As to whether this "depth loss" will simply reduce you to depths that existing land discriminators gives you, is up for debate

The TDI is awsome. However, unless you're hunting in "Hot" mineralized ground or at the beach your money would be better spent elsewhere. In good ground you'll get the same or better depth from an MXT (especially with the new D2 coil or super 12). The benefit of the TDI is when you are hunting in ground that masks good targets due to high mineralization. If you are hunting in ground with an average ground phase reading of 58 - 70 then you are in average ground. Anything in the 75-80+ range I would consider heavily mineralized. The difference in performance is that in heavily mineralized ground a VLF detector will sound like a telegraph where the TDI is smooth and predicatble just like a VLF mahcine in average soil. Just my observation. Good Luck.

I own a whites TDI and it is a PI!!! it will out perform any VLF in any ground anywhere for depth an MXT wiil not even come close to the depth of the TDI unless you use it for a shovel and dig down a couple of feet and then turn it on.I have extremely mineralized ground where I live and my VLFS do not sound like telegraphs but my depth of target detection is signifigantly reduced, and almost all of my targets over two inches with a VLF all sound and indicate a good target in my ground when the target is iron, the mineralized ground really masks bad targets, also I have hit good targets on the surface and depending on how much black sand is in that spot my VLFs miss targets, I have so much black sand and hot rocks once on the river I encountered a field of them about the size of foot balls and smaller 100 yards long on the inside curve of the river, if you want to find very deep targets a VLF is not the answer in ANY ground a PI will pick up much deeper targets in non mineralized ground!! It is money well spent for a acurate deep seeking detector
