I think Ted and I just compared notes in another thread,at least through a third party, but my experience has been better than his. I have had one about a year and really like it. For a while I went back to an Omer Zoom, but that drives me nuts because of a problem that may be more specific to those of us hunting white sea bass in California.
We have to pull our snorkels out of our mouths as we leave the surface in order to keep from leaving a trail of bubbles that bother these sensitive souls. It seems like I twist the lower portion where it swivels on the upper portion, so I often end up with the snorkel pointing sideways after I put the mouthpiece back in my mouth. I like the Stable because it just drops away and does not require a turn to get away from my mouth.
I also like the way it is protected from the front so it gets a bit less water in it when swimming into a chop.
In defense of the Omer Zoom, guys who are a lot better than I am just love it, but I'm just giving my impressions.
