The original files have been deleted due to my computer upgrade and the Tdi Pro that was modified has been sold. I'll check my backup drives but it is not looking good.

When I hunt for gold I bring a 'test' nugget with me so that I can set the machine for the location that I am hunting. For example if I know it is a small gold area then conductivity will be set to Low in hot ground. Larger gold requires me to set conductivity to All because of the ground...

zanoid please rephrase the question.

Both good coils, if you want to save a money I'd just go for the 8" mono. All the best.

I have the Detech 8" mono and the 11 x 6 mono. For weight and balance I recommend the 8" mono. For small targets I also recommend the 8" mono over the larger coils. White's 7.5 mono, Razorback/Miner John 10 x 6 mono etc are all good performers and balance well with the Tdi Sl. I wouldn't go...

Because I finally wanted to sort out my Tdi SL/SPP ground balance issue in hot ground I bit the bullet and purchased the Philmore S38 vernier dial. Simply pull of the ground balance knob and fit the vernier dial in its place. I positioned the dial so that when set to zero it has ground balance...

After reading this thread I decided to see why my 'SPP' conductivity didn't work. So I opened her up and disconnected and reconnected the plug from the board. I had failed to make a good connection when I replaced the Tdi Sl board with the SPP board. Humble pie on my part and poor workmanship...

Looking at the photos we can see two Tdi Sl machines, the new one in light tan has the Tdi Sl motherboard, the other machine has the SPP motherboard. The SPP has ALL the switches connected on the board as on the Tdi SL. The SPP does not permit conductivity, frequency and it is set to 10 on...

Images of White's last SPP circuit board on left, on the right is the Tdi Sl. Please note there are real differences. Hope this is of some help, all the best for 2024.

Sold.

White's Tdi Pro modified, sale pending...

Folks sure like pictures of the circuit board. More as requested.. all the best.

Some images of the circuit board from the modified Tdi Pro Oz, for those who understand such things....

In relation to the modifications my friend said they focused on smoother threshold and extra sensitivity, when compared to the stock Tdi Pro there is clearly a smoother threshold and a marginal increase in sensitivity. Again the modifications were done by Luke. I've used the machine on the...

Coils included are Nugget Finder 14 x 7 mono, Coiltek 6 mono and Miner John 14x8 folder mono. Coiltek and Nugget Finder are good but well used, the Miner John is excellent with light use only.
