ATX and Whites TDI?

I was just at Garretts website and watched the Videos and it looks like the ATX
will dance circles around the TDI. I can't say because I have never used them.
 
According to Steve Herschbach who has both of them, they are about the same performance. One is heavy and much more expensive, but waterproof, the other is lighter and cheaper with many more accessory coils. If waterproof "floats your boat", the choice is clear. Otherwise wait for more data.
 
I have a TDI, and based on all the excellent ATX videos this is my conclusion:
The ATX has a better frequency tuning system (automatic)
The ATX has auto ground balance with lock and tracking. I've had some challenges with my TDI SL manual balance, but manual does have an advantage of off-setting the GB. I have the auto GB with track and lock on my MXT and really like it.
The new ATX DD 10x12 coil looks to have the combined strengths of seeing small gold, seeing larger, deeper items, all while the DD coil helps manage EMI and mineralization. The threshold sounds as smooth as my TDI SL
The ATX appears to be sightly deeper than my TDI.
The ATX is approx. 50% more expensive than the TDI.
The ATX is heavier. But comes with a sling.
The ATX is waterproof, and coil free with very convenient packaging.
 
Have not got one or tried it. And am still awaiting some decent proper field tests of the ATX against my current machine a GPX 5000. But have heard from a bloke that has had a go on the ATX and once used a TDI. He was not impressed with the TDI but is with the ATX. Wish he had tried it against the 5000! From what I have seen though in tests, though again I don't feel they were the greatest type of testing, the ATX appears a much better machine than the TDI.
 
In a nutshell I believe the ATX falls somewhere between the standard TDI and GPX 5000 for overall performance but it will take more time for it to all settle out. I have all three, ATX, GPX 5000 and standard TDI (not TDI SL) and I can't give a real clear answer yet myself. My gut feeling on getting the ATX was to ditch the TDI but the weight difference and the fact I can hip mount the TDI made me hesitate. I much prefer the well modulated audio response from the ATX but like the single tone (high tone or low tone) on the TDI versus the dual tones (hi-lo versus lo-hi) on the ATX. The bottom line is if forced to ditch one right now I would let the TDI go. I may still but I am going to give it a bit more time to sort out. I have a few things yet to try with both.

Anyway, since Rick was quoting me I thought I should clarify a bit directly. As he notes if you want waterproof it is a no-brainer. I think the ATX clearly outperforms the TDI SL but at much great cost and about double the weight. The ATX versus standard TDI it TDI Pro is closer but I still think the ATX is the better machine. If it just weighed 2 lbs less I would be raving about it.
 
Seems to me that the ATX has just a bit shorter second echo than the Infinium has with the hi-lo double tone, making it less annoying and easier to move on to the next target if there is one close...not much, but just enough to be more bearable for long hunts.

I have done two side by side tests with both the TDI Pro and the ATX.

The ATX is much better on small gold at the beach in wet salt water sand and on small nuggets. I tested a gold chain at low tide https://www.youtube.com/watch?v=xB2hlVdYZ3w

In terms of depth in wet salt water sand, its hard to compete with the TDI Pro. I did this comparison last week https://www.youtube.com/watch?v=dN_oObIPjS0

I spoke with the folks at Garrett and they want me to try some ground balance adjustments so I'll be back at this beach again in the next week or so to see if tweaking the GB gets more depth.
 
Last week, I mentioned to Steve Moore (at Garrett) that I was disappointed in the results of the ATX on the depth at the beach vs. the TDI.
He made some suggestions about how he would try to GB the ATX at a salt water beach.

Also, according to Steve Herschbach:

"The ground balance circuit in a PI robs depth. The TDI with ground balance off is like a slightly more powerful Surf Dual. Mainly because of the battery power behind it."

"Now, if the ground is bad enough, you turn on the ground balance to get rid of ground signal. But a simple air test with a TDI will show a depth loss of maybe 25% when you turn on the ground balance. So it is best to use no ground balance up to where it gets to be a problem, then switch when you need it. Also, all the tone and target id stuff only works with ground balance on."

"The ATX is locked into ground balance mode, as is the Infinium. The GPX 5000 can shut it off. OK, what that means simply is if the ground is mild enough, you are better off with ground balance off."

Steve H. - thanks for the great insight and tips!!

Garrett said to 'Mess with the GB' on the ATX!? It does this automatically! As usual, Garrett's misleading comments to sell more product.
 
YES,,,,YOU MUST BELIEVE THAT MOST EVERYTHING COMMING FROM GARRETT IS SLANTED INFORMATION.........EVEN THEIR OLDER VIDEOS WHERE THE GROUND HAS ALREADY BEEN SALTED........
 
You mean the Garrett website has videos showing the ATX out doing a White TDI---who wooda thunk it.
Go on utube and see "Atx vs. TDI Pro on the beach with a nickel".

Yep I agree the ATX was giving a faint signal at 16 inches and the TDI pro was doing it at 18 inches that's a 12.5% depth increase, and too much to ignore.

I guess most machines have good and bad points,when you get questions like this ask a comparison between any different make or model of detectors,you will always get loyal followers shouting from the roof tops that the machine or brand 'A' is better than brand 'B',folks who have spent alot of hard earned money on a detector rarely admit they made a mistake.

Must admit i had looked at the ATX mainly i guess because its waterproof,but when i sat down and thought about it when was the last time i used a machine fully submersed in water,the answer was never,so why pay for a high end waterproof detector,so then i went down the TDI Pro route and done my thorough homework on that machine and that ticked all my boxes from what i wanted that machine for,which is basically deep hoard hunting and artifact and nothing else..

Of course after doing the research and homework i finally located a TDI Pro and must admit have never regretted it,when i am looking at a new machine and in some cases 2nd hand specialised machines i will keep them for a very long time and this could be 10 years plus,so i also have too take into account the reliability long term as well.

I find that detecting folks are like car owners,once they find a reliable brand of car say like a Ford they will often stick with that brand for a very long time,loyalty is the word that i would use.

No one machine is 100% perfect,basically VLF machines have changed very little in recent years,apart from when they add a new non essential feature but then command the highest possible charge that they can get away with.Just my personal opinion of course.

Due to the nature of you Detecting needs no other PI would work at your locations, Also being able to select the metal Type has a huge advantage over any other and the SL just does not have the Horse power you need, I have a couple of PI's but I try to use a VLF as much as possible because the SL does not have the Power of the Pro.

You can't compare your SL to the ATX---compare the TDI Pro--on the beach the Pro is Deeper on a nickel than the ATX. Go to utube.

Yeah we said that, But the SL and the Pro both have skills the ATX does not as in being able to Disc out certain Items,
 
I have a White's TDI and I just ordered a used Minelab 18" Mono coil for the GPX series to try on it. I'm trying to get just a few inches deeper on the Treasure Coast beaches of Florida.

No GB has been required here. What can I expect over the stock 12" coil and the Jimmy Sierra T-foot coil (18" by 5")

Thanks,
