The passing of a friend unfortunately has led to me taking ownership of a modified Tdi Pro. My machine is mounted on an Anderson shaft and is factory spec. My old mate had his machine modified to smooth out the threshold and to add some sensitivity. The specifics related to the modifications are not known by me, other than that they were conducted by 'Luke'..Oz Digger.. This happened some time ago. So the modified machine is probably not a keeper, I don't want two Tdi Pro machines.. The opportunity to do a comparison cannot and should not be ignored.
My intention is to focus on small gold performance, the threshold smoothness, the ability to use gain, basic performance and handling characteristics under different circumstances. The machines will use the same fully charged battery pack, same coil, same targets, same test location and conditions on the same day etc. Trying to minimise external variations. I'll start with the usual useless air test. Later I'll follow up with in ground testing on the actual goldfields in mineralized soil. Test coils will be with a small coil and a large coil. Targets will be gold only. The 1 grain ingot, the half gram gold coin, a half sovereign gold coin. Some real small sub gram nuggets to see how small we can go.. There is a process involved so I'll take my time and do it right. Any specific questions or suggestions, speak now or forever hold you peace.. I'm only doing this once. Once it sold it will be too late to revisit..
All the best.
Just arrived in the mail, Nuggeteer 18 x 6 mono, mounts nicely on the Tdi pro using a Minelab lower rod. It is weighty at 1 kg but easily balances on the Tdi Pro, just don't have any metal in your shoes..
When the weather clears I'll go down to the beach and give it a good run. Useless air tests, test garden results and beach run results in the very near future.. karelian

Was here with the with the 7.5 and Hi-Q coils , it leaves tomorrow,, absolutely no comparison to the big box TDI ,, and the HI-Q isn’t any better at air tests than the 7.5 coil,, Whites says it’s for relics as well as gold (HI-Q) maybe gold,, not relics having pursued relics for the past 35 years this combo isn’t it ,, I’ll stick with the big box and the standard spider coil,,, or use my other pulse the M/L GPX5000 ,, and as someone else had written ,, we shouldn’t have to buy or make higher voltage batteries to gain depth ,, don’t get me wrong I love my Whites detectors owning1, Big Box TDI ,, 2 , 6000 xl 1, Blue&Gray, 1,MX Sport ,, and 1 Eagle in Brand New mint condition too pretty to use ,, this package is advertised as a gold and relic detector / that HI - Q isn’t for relics of much depth before it taps out
I'm from France, working with a GPX4500 of 2003.
Yesterday when I started this old guy, I was affraid by this problem :
- Sound when the treshold start is strange.
- The autotune (research for free frequency) is a stable sound, with no variation.
- And no power ! about 5 inch max for my metal digging pickaxe.
I tried some factory resets, but the problem is always the same...
I tried this one with another disc, trakking button, cable, headphone, battery, the problem come from the main box...
Anyone knows this problem ?
Thank you and have a nice day.
Hello everybody on the forum, hello Steve!
I am a relic and coin hunter in Europe. Among other detectors I have used Minelab pulse machines since 1999, so I have a small arsenal of Coiltek and Detech coils for SD, GP and GPX models. ... and now I have set my mind to owning a White's TDI SL as well. I heard and read that Coiltek and Detech coils for SD, GP and GPX models can also be used on the TDI.
Is that true??
I'm looking forward to your answers! Take care and good hunt!
