The Spectra Dry is nothing short of the ideal snorkel. Its large-bore upper tube allows plenty of airflow, and its dry top design actually seals the tube when the snorkel is submerged so no clearing is needed upon resurfacing. An efficient purge valve expels any water that might make its way into the airway, preventing that annoying gurgling sensation you get when breathing off a "wet" snorkel. The lower corrugated tube is flexible so when you switch to your regulator the snorkel mouthpiece hangs out of the way.
