Likewise I await your results and tests

I had seen this modification several years ago with R86 on a French forum. I know that some French people had made this modification successfully but had not made (had no knowledge) of the C42 modification at the time. I am tempted like you to remove this resistance. For the voltage, my previous tests with a TDI plate (not SL) that ended in failure no longer push me to go higher in voltage than my 4x18650 (about 16.7V).

Great job ! For losing depth :

As I wrote on the post before, the gain in depth is undeniable and even surprising. For small targets I can't say because I don't hunt gold nuggets, I use it on the beach and on the ground for coins, jewelry etc. On my TDI SL the mods performed are: - C56/D20/D21 - C42 switch (without the 1k resistance) - Potentiometer for the volume - Battery 4x18650 The one not performed is the one on C20/C21 because I do not want to lose depth. Carl is the best placed and most competent to talk about the TDI SL. So I will add this 1k resistance. Being in France on low mineralized lands compared to other countries, the results may be different.

Sorry for the response time. No, I had exchanged with several people, and I had not installed a 1k resistor in series. And I use it like that. Is this a mistake? On air tests with modified battery (4x18650) fully charged, I get with the activated switch an additional difference of 5 to 10 cm depending on the type of target. I did not make the modifications on the capacitors (C20/C21) because Carl had confirmed on a post that if we changed them, we gained in sensitivity but we lost a little in depth.

The jumper is made with the Test Points 2 and 31. When I made this modification, I soldered a wire on the TP31, a wire on the TP2, I installed a switch (2 positions) next to the speaker (only place really available), I twisted the two wires up to the switch. Why a switch? Because as the gain increases you have to be able to “control” it and there are places where it is difficult. So when I need it and possible I put it in the ON position. Don't touch R9 - R75 - C42 On TDI SLs manufactured after 2015, D20, D21 and C56 are absent (modification taken into account by Whites). On those before 2015 they are present. I also installed a potentiometer for adjusting the audio volume (like on the Beach Hunter)

Hi, I have a problem with my Musketeer X, I bought a used TS1000 Treasure Searcher coil (not the Slimline) which according to the seller works wonderfully on his Musketeer Advantage. But on my Musketeer X, as soon as I plug it in it emits a brief and repetitive sound to infinity. My question are the coils of the Musketeer Colt / Adavantage / XS etc compatible with the Tribune / Sterling / Musketeer X? I checked at the ohm-meter and I can't find any value between terminals 4 and 5 (while on my original Supersearch, I get a value around 100 and a few ohms). Thanks.

Good news Jeff.

It's ok, Gain 100k 1%, Volume 100k 5%.

Hi Jim and Sven, Sorry for my question maybe my english isn’t very good and so cell was not understood. I don't have a Beach Hunter TDI, I wanted someone to tell me the value of the resistors that are of the Gain and Volume potentiometers. There on the photo I can see these resistors from afar but not entirely. Thanks.

Hi, Someone who has the TDI Beach Hunter could tell me the value (color code and %) of the resistors behind the Gain and Volume potentiometer, and a photo of each please? Thanks.

Hi, I wanted to share a simple website from an enthusiast French guy. Perhaps unknown across the Atlantic, listing many old brands of metal detectors, with photos etc. For the nostalgic https://detecteurmetaux2.blogspot.com/

Thanks.
