The other one I ordered from a Dutch store because I had to wait for (much)more than a month on Aliexpress. This second cable is 20awg 5×0.5mm². The wires are thinner so this label of 0.5mm²doesn’t make much sense. Make sure you have the flexible version !!! These have several very thin small copper wires inside, and don’t buy a solid-copper-wire type because then you will have a long stiff cable. You should be able to tell the type from the photo.

If your detector is making different beeps whilst not going over metal, but it does so consistently when moving the cable or connector, the problem is probably the cable or connector. Whatever moves is causing it. 2) Also can mean some water went in and gives a false signal because the electric signal goes where it shouldn’t go. Or option 3, the wires that are soldered inside the connector (6-pin with Sovereign) can have loosened up. Also had this problem with my very old Sovereign: after a while it started beeping at every swing. As I opened the end-of-coil connector, one of the 5 metal parts on the inside that are soldered to the wires simply fell off. Oops. Those are quite easy to fix. Just need a new 6-pin connector.
Fixing broken wire comes in two parts: figure out where it goes wrong, and then cutting that bit out and soldering cables back together. Don’t forget the shrink tube before you solder :p You can look up how to solder wires together on youtube.
Which connectors for Minelab Sovereign and Minelab Excalibur coils ?
Here are the metal versions of the 6-pin connector for the Minelab coils that go with Excalibur (if you modded it to use interchangeable coils) and Sovereigns. I guess they are as non-waterproof as the ones I have. Thinking I could have waterproof connectors for cheaps, I bought plastic connectors via a Chinese website but they are dodgy as hell. They are probably not waterproof and even if they are, you can just bend the connector and it will break open due to the weak plastic screw threads. So if you want it waterproof, for example to have interchangeable coils for your Excalibur, then you might want to look at other solutions like truly waterproof 4-pin connectors. Most coils only use four wires so there is no actual need for a 6-pin connector. The disadvantage is that you will have to change the connectors for every coil/detector you want to use but if you stick with them, I don’t see it as a problem.
Open up the connector that you have, and don’t forget to write down the number of pin that each wire is connected to. It’s faster to make a few photos but trust me, you don’t always see it very well on photo afterwards. I did that without writing down and then had to rely on photos, and it was really hard to see.
