I have a NEL 5" Sharp for Gold Bug Pro. Hardly a scratch. The NEL Sharp sticker fell off but serial number sticker still on coil. Will also work on G2 and other similar detectors. Will trade even for 5" stock coil for Gold Bug Pro. My coil works perfectly and has the coil cover. Yours must be in excellent condition and have the coil cover as well. I just want all stock Fisher stuff for my GBP. I also own the 10 Elliptical and 11" DD and want all factory stock coils. Maybe doesn't make sense but it is what it is. PM me if interested.
