ive got an excalibur with 10 inch coil.it works the way its supposed to.the headphone housings have been changed but it still has the original waterproof speakers,it needs a battery pod if its to be used underwater as the one thats on it is cracked.it has regular alkalines in it.the coil cover has some type of glue or sealant holding it on.it has scratches here and there as its been used..will trade for another detector or make offer...thanks daniel [email protected]
