Hello Ivan,
Daddy is right, it's a custom decal I added after adding the inline probe.
Has all of Reg's mods, and a recent inline probe connector I added with toggle switch between both coil connectors. Was experimenting with different probes, found by adding a TDI connector to the uniprobe probe with some modifications it works great with the TDI. Other probes work as well, Reg passed one to me and I have one off of another one of Eric Fosters Pi's.
The probe that surprised me, Was the thin lightweight uniprobe probe it is very sensitive even with TDI pulse delay at 10us. Reg has mentioned the TDI may not be a true 10us, close though and I feel the same because my GoldQuest SS operates at 10us and it is slightly more sensitive than the TDI. Regardless, TDI is still very sensitive maybe somewhere between 12 and 13us.
Sorry for the confusion, throught it would be neat and if White's was to come out with another TDI model it would be great with one similar to this Pro II set up.
Take care Ivan, Hope the remaining year fills your pouch with West Coast gold.
Paul
