White's TDI- White in Black Monster-Gold detector
My review of WHHITE's Pulse scan TDI pulse induction detector. I call it White in Black Monster.
It's USA White's top PI(pulse induction metal detector) build for main purpose as GOLD detector with conductivity discrimination abilities, also be able hunt coins and relics to easy recognize Iron from more valuable metals. Discrimination works perfect in any soil doesn't matter if object is big or small and also in any depth which coil can reach. And is DEEP.High conductivity metals(iron types-low sound) Low conductivity metals(gold etc-high sound).
It is only Pulse Induction detector in the world made today which is able to do discrimination in bigger scale when you combine pulse (microseconds) and ground balance
settings dial. There is a lot to experiment and learn from Field manual supplied with Operational manual and get much,much more of it by your experimenting.
Is working on the same principles as famous Australian made Minelab's SD 2000/2100/2200 series-GP Extreme,3000GP,3500GP,4000GPX,4500GPX gold detectors with some technical differences.
Another things are that you not need to be worry about HOT ROCKS at all.
This detector is ignoring hot rocks and not only that, you will pickup nugget sound under Hot Rock with no problem the same as it was in normal soil
as I did.(0.2 gram will be hard but is possible,but anything as 0.5 gramm up has good sound. You do not to be worry even in areas where for example hot rocks are so many that
is impossible to hunt with other detectors at all. Now I love those areas,because they been deserted. I mixed myself on one trip with Minelab user 3500/4500. He has been worry
about hot rocks in that clean area so much he better was hunting mine tailings.
I pretend I do not like that area also,reason hot rocks,but I never understood fully. So when he was away I pull out my VLF currently made very good one (Garrett)
I swung coil and I understood immediately. In some spots sounded in earphones as MACHINE GUN continuously.
YES- this detector is proven GOLD finder in hardest Western Australian environment in the fields cleaned and wipeout by Minelab's for decade or more.
Those tenements free for public now (BLUE or BLACK) were crossed many times by Minelab's owners and tenement's holders.
Maybe I was lucky, or detector as White's TDI with different parameters managed find what other detectors left out.

I have it 6 month and I was on the beach also,this detector doesn't care if sand is wet,dry,salty not salty or is it too salty. It is quiet the same as on or normal soil and
is deep.
Tried also on lake Austin (very,very salty) and too many,many HOT ROCKS, no problem at all.
I didn't bend one time,while Minelab owners got sored back.
Minelab was on my mind before I bought this one, now I am not concern to pay unrealistic prices as you see those ridiculous prices on eBay auctions some are reaching second
hand prices $8000.00 USD I think is illegal as 4500 is not vintage collectable model but current.
On the other hand people who can afford them are mostly retired couples in Australia, I met many of them, they will find couple 0.2 gram pieces and detector is for sale in new
Everyone I met is finding with GPX's litle pieces of little value so recover cost of detector in their lifetime never happen or ?.
Is different story with TDI, which costs 1/4 of Minelab's GPX4500 and if you buy small 7.5 inch coil (Whites) you'll recover the same also smaler subgram pieces as GP Extreme,3500 which I tested agains it.
And you will pick gold under HOT Rock which you can not do it with GP or GPX detectors if you don't kick out hot rock and only than you discover gold is there. In clean not
contaminated ares by trash,with thousands of HOT ROCKS,you will bend only for GOLD.(100 % true).
My opinion on coils,do not waste money on Coiltek coils( I made mystake and listen advise of some dealer from Alaska on some forum who is by some people recognized maybe more than
should be). Coiltek are Super coils but not for Whites TDI. I bought Coilek Gold Stalker 9x14 mono and I tried others also. They do not harm TDI but they harm your pocket $.

Maybe they work in Alaska in some soils ,but Coiltek coils are working with limitation on TDI.
What Coiltek coils do in some soils when used with TDI? They will dictate to you how to set TDI in that environment. For example if you will set 10 micro seconds and you are
after to chase small gold, with Coiltek coils you will not able do proper ground balance in some soil conditions,unles you set up (pulse)microseconds into different value as
you do not want, you'll be pushed to hunt by coil in different pulse as you wanted,so you will loose ability to hunt small pieces for example.
This will never happen if you USE original Whites TDI coils(small or big) in any invironment.
Whith Whites coils you will be able setup pulse as you want and be able ground balance TDI as smooth as you need to anywhere in any conditions.

Technical stuff.:
Some say is hard to learn. Is not. You need to know glossary for detector use,primarely ones as Treshold,Ground balance etc. Just read manual,
switch on and go.
Manual is bit confusing only for one reason,that Ground balancing ON, what on MANY detectors means Automatic tracking(balancing ON) is actually OFF.
As I see it due this fact whole concept of understanding so simple manual is getting for some people difficult to digest and understand.
So I made my own manual. Just remember:
If you are forced to be on Manual Ground balancing(ground balance switch ON)(conductivity switch in middle) due to high
mineralization,or you want to be able have recognize between metal conductivities-just remember 3, 9, opposite rule, and 6 stays 6.
-meaning : pulse delay dial mark on left, ground balance dial mark on right , pulse delay dial mark on top, ground balance dial mark on 6,
pulse delay dial mark on right, ground balance dial mark on left
- first set Pulse(as desired) left , top or right, after that turn Ground balance dial equal to 3,9,6 rule.
-than move coil up down, towards land on clear spot of any metals, no sounds leave settings all done.
-if high pitch noise when pushing down, adjust ground balance dial slightly right until no sound
-if low pitch noise when pushing down, adjust ground balance dial slightly left until no sound
-treshold as desired to have quiet detector without additional noises.
That is it,you can than switch TDI OFF anytime and just switch On where you finished all stays set up,unless you do not
accidentally touch and turn any buttons.
If you notice that mineralization changed(all the time you are closing down you have high or low noise),just even as you go and walk
turn Ground balance slightly left or right as needed to loose aditional sound and that is it.
Will be ground balanced on the go,no problem. Due to easy switching OFF and not loosing settings battery can last even 2 days hunting.
I was using pointer,so I switched OFF all the time I dig,all the time I rested etc.

Happy hunting-27.Oct.2009(sorry about my english I know is not perfect as second language,but I hope my review will help you + or _ )

1000+ nuggetts and counting!
Lets be honest, nothing will touch the minelab GP range of detectors for depth or sensitivity in any ground,for any target! Yes they cost a lot and are heavy and cumbersome and discrimination is not much good at all ,BUT! after 25 years of detecting coins and gold, and testing every make old and new ( except c-scope, never had one!)you never cease to be amazed at the power of this machine! i have been cleaning out an old spot for coins with my gt sovereign, not a lot of trash, but sandy soil and very deep coins. found about 25 "keepers" from 1880-1946 down to about 10" deep. Penny's, halfpenny's,1 3d, the odd sixpence some nice old buttons etc . then tried my GP 2200v2 and it was like no one had ever been there!! found over 30 more coins! some 20" yes 20" deep, and all the tiny silver 3 pence coins were at 10"-12" well out of range of the gt sovereign. and a small 1860's police button at near 2 feet!! with a 18" coiltek mono coil. go to an old coin spot with a gp detector and IF there isn't too much rubbish (and the soil is soft enough to allow coins to sink that far, or old enough!) you will be amazed at how deep you can get coins. and as far as gold goes. why would you even try to use another detector?? 5" deep on .4 of a gram and my mate got a 46oz nugget at 2.5 feet!( took 12hrs to dig in rock hard ground and 37deg heat!! PS try a GP on the beach with an 18" mono coil... but take a shovel!!
