  • Can I shorten the Minelab Sov GT Tornado coil cable?

    For the life of me I can't see a reason why I shouldn't be able to.
    Here's the way I see it....

    Minelab uses an unshielded multi-conductor cable (unless there's something to the jacket that I don't know). As pole mounted, my cable is wrapped around the metal shaft 15 times. So that makes for a mild inductor along with the extra resistance of a long cable.
    I can only see an improvement in performance as a result of shortening it.

    However, when I posed this question in a Minelab forum elsewhere, I got one reply that claimed 2 different people he knew observed performance loss because of it. He wasn't claiming first hand evidence, just reporting a potential concern.

    I want to mention that I've read the threads about Sov coilbuilding and didn't find anything relating to cable length or its importance.

    The Sov transmitter is forced digital, not tuned; and the receive has the preamp inside the loop. So shortening the cable will have no negative effect on either TX or RX.

      Thank you for clearing that up Carl.

      While reading I saw a post commenting on the signal from the coil amp and how it responded to ferrous and non-ferrous objects. So I looked at the return signal and while I didn't observe the difference I was surprised to see a scoped response to an object before an audio response from the box. Don't know what (if anything) I can do with that observation, but I found it interresting none the less.

        Yes. Try 33". I've heard some of the ML boys say it makes the machine more sensitive!

        ROFLMAO for SO many reasons on that one though!!

        I recommended 3" on the UKDN. I bet someone on there went and did it too!!
