Hello all! I have an old original Excalibur, the one with the horseshoe coil, which I haven't used in.......well a VERY long time. The batteries leaked and ruined the holder so I will have to do something about that of course before use. I do see some mods which some have done to the newer models and wondered if any of you have messed with the older model.....or even if it was worth the trouble versus just buying a new Excalibur II. I would appreciate your thoughts. Thanks in advance.
