Well I used to own a Minelab 5000 bought for $6200 sold for for $6000 A great detector no doubt,but is it worth the $6500.
Whites TDI Pro OZ series retails for $2100.
Both Pulse Induction detectors,the Whites dont have the LCD display and all of the timings like the Minelab,but you can use all Coiltek and Nugget Finder coils on the Whites as you can on the Minelab 5000.
I've heard that the Minelab is superior on depth with small targets,personally I'm tired of digging down a metre for a fraction of a gram.The Whites with a 6' coil is quite good on small targets at depth.
Both will find big nuggets in shallow and deep ground.
The sound they make is very similar,perhaps you need to swing the Whites abit slower to get the same response as the 5000 on small targets.
The other Pulse Induction detector is the Garret Infinium $1200 however the coils are'nt interchangable.
I think I'm going to get a Whites TDI OZ Pro series,has anyone used one,your thoughts would be appreciated.

yeah have recently aquired one from tony mills at goldsearch australia and its the business ,used correctly and with the right coil (this is paramount as tony told me) its fantastic bear in mind that the guy who invented pulse induction is eric foster (whites) and doctor bruce candy who is minelab used to work for whites as a technition so at the last minute before purchase i was sold on whites after being on the ml 5000 trip for a coupla yrs before i could purchase , dollar for dollar u wont get a better machine . i got the bonus 6 inch goldstlker coiltek coil and the nugget finder 16 inch coil recommended from tony himself ,less than a third of the price with almost same capabilities . theres alot of ml indoctranation even myself ,after a lengthy talk with tony i was reassured that my choice was the right one

"doctor bruce candy who is minelab used to work for whites as a technition"
G'day sidneymelbs, I think you will find that this is not true! Did you ask Tony why he always uses a minelab?
BTW, he has sold out of his detector shop.

How about a field test ' same ground between the two . Can the 5000 out- do the TDI 3 to 1 as per it's price ? ;D

Heres an owner from canada discussing how the G/B affects depth. "I have operated the TDI for three years now and offer the following observations. Operating the TDI with ground balance turned off is seldom practical as there's too much threshold variation. With ground balance turned on, target depth can be quite variable depending on the GB point of the target. Depth will be least when the GB of the target (the point at which the target transitions from low to high conductor sound) is near the ground GB value. In a worst case scenario, this can reduce detection depth by up to 50%."As always you pay your money and make your choice. My view? Well I don't know that it's 3 times better but If you were going to spend 4 months in WA, I'd pay the extra and take the 5000. Truth is, I was hoping that the TDI was going to be better than it is, I wanted to buy one for my wife, they can do some things better than a 5000, better discrim, working under power lines, etc. But people who want to believe that they are better, or will find more gold than a 5000 are having themselves on.

I have a friend who is what i would call a professional prospector, finds large amounts of gold every season in WA ie 15-40ozs every year for the past 15 years and have witnessed at least 3 of those years end of season tallys and they have all been spectacular. He has both the 5000 and the whites and only uses the whites when he is searching for quartz speci's when the gold is fine flour gold etc not nuggety gold...that is the only situation where he can see a benefit to using the whites over the 5000

It would be a VLF Whites detector , starting from 1992 with their good Goldmaster models . Best thing that ever happened is almost every-sheep uses a PI unit only ' these days ;D Thanks Bobby.

Yeah. true. but I also own a Whites GMT, great little detector!
BTW, Whites are at the moment testing a very, very good Pi detector, so things could get interesting...............and cheaper. ;D

Hey there...have been using the TDI Pro oz now for six months...yet to find the elusive yellow stuff...but plenty of nails & shot...as an indicator of depth...I have found a $2 coin at a depth of 500mm at the beach...so sensitivity is great. No use stating the results some guy in Canada is getting...the TDI Pro oz is different to the US model...the oz is for our mineralised ground...the US model isn't. No denying the GPX5000 is the pinnacle...though with the price difference it's out of the reach & justification of most.

I hear constant reports from the TDI owners about how good there detectors are but am yet to see any gold?? I know three blokes who own one each and none of them have ever found a nugget! Technically in a good operators hands it should be able to get gold, but I am yet to see any of it. I have seen lots of finely speckled specimens found with GMTs like carms said, but have never seen a successful prospector using a TDI.
My two cents Diggerdude

I saw a whites TDI take out 40ozs(15ozs gold) of speci's this season....the 5000 wouldnt make a noise with these speci's but one of them had over 2ozs of gold in the one bit of quartz! Saying that, the guy who found them owns a 5000 and wouldnt use the whites for day to day prospecting Im also not a whites owner, i own a 5000 and would only buy a whites if i knew of places with fine flour gold trapped in quartz lol.. so there is someone who paid off there whites lol
