The world’s first and only nationally syndicated radio show devoted to diving! Suckin’ on-air since 1997! ScubaRadio is likely the most downloaded scuba themed podcast in the world as well! It airs every Saturday from 3-5pm EST on radio stations throughout the US and worldwide both live and through archived podcasts. Each week Greg The Divemaster and friends guide you through the latest dive related news and information often combined with an irreverent twist. Imagine hanging out at a Tiki bar after a day of diving and sharing fish tales with friends. Join the conversation live at 1-888-88-SCUBA, through email, or by clicking on the “Get on the air” tab 24/7 right here at ScubaRadio.com.
