Have a pair of the Black Widows already - excellent but hot, heavy, vulnerable to getting bumped and blowing my eardrums when I switch from main coil to probe. I think I have the noise limiter switch disabled; because I about screamed the first time that happened when I put them on my upgraded F-75. Never used to do that.
They also weigh about as much as my F-75 detector! I bought the Widows for my audio-only Musketeer Advantage. Like the Cones of Silence - you hear no ambient noise. I have seen feet and looked up to find someone talking at me that I could not hear at all.
I also have a single-earpiece Rattler. What I am looking for is something with an earpiece that size on both sides and without a bunch of exposed knobs and switches that have to be checked for operation each use.
