Headphones. I take it they are water Proof. How does the audio compare to your Excal. The blue ones on my Excal suck period. They spin on the flex adjustable shaft and pop out of the snap in holder. Mine is going back to Minelab and I am going to get something done about this very bad headphone set up. I think I am going to tell them just to put the yellow phones on if they are waterproof. I just want to see what they look like. I don't like the Gray ghosts as I have a lot of high freq. loss. I am trying to get a set of waterproof Timber wolfs made for my new Excal 1000. One thing is for sure, these blue pieces of junk are coming off my Excal you can bet on that. Thanks Jerry aka Tinfoil.
