Comments about Sherwood Sherwood Sabre Snorkel:
I had an older model but it retained some water after purging which required a slow breath and a second purge or release the mouthpiece altogether after surfacing. But Sabre works perfect. One blow dries it out completely and it never needs a second blow. The angle is perfect and it always stays out of water during snorkeling. It was so comfortable that I have forgotten to replace it several times with my regulator :)
