Hello everyone, does anyone know of a good conversion kit to change an Excalibur over to a replaceable coil system? I want to use a variety of coils but still keep it waterproof so taking it apart and soldering a new coil in every time is not an option. There should be watertight connector you can install inline with the existing cable where different coils could then be swapped around. Maybe something like what Minelab uses for the battery connection? Any experience in that area would be appreciated. Also, any recommendations on big coils that will still detect small rings? Thanks, Mark
