SHERI DAYE is an avid spearfisher with over a dozen world records and a women’s National Championship title. She is the host on “Speargun Hunter,” a TV series on Outdoor Channel. She organizes and hosts “The Blue Wild Ocean Expo,” an annual event in Ft. Lauderdale, Florida with the proceeds going to charity. Sheri is a corporate manager with a mechanical engineering degree and an MBA. She serves as a member on the Board of the two world-record keeping organizations, IUSA and IBSRC. She is a co-inventor of the Freedivers Recovery Vest, and on the Advisory Board of Oceanic Safety Systems.

She says, “Of all the methods of harvesting fish from the ocean, none is more honorable than freediving, but it comes with an inherent danger of blackouts. The more experienced members of this spearfishing tribe have a responsibility to educate the younger generation of divers, so that they can live long, safe, and productive lives.” Learn more about Sheri at: The Blue Wild Ocean Adventure Expo

Thumbs_Kollias_150x150DIMITRIS KOLLIAS was born in Piraeus, Athens, Greece. He became fascinated with the aegean waters and fish early on. At 18 he shot his first “rofos” – grouper, a legendary fish among Mediterranean spearos. He wrote articles for Greek diving magazines and became editor-in-chief of two. In 2002, he published his first book, Spearfishing, the Full Method. In 2004, he and Nic Kouvaras started Deep magazine, dedicated to spearfishing and freediving, which has become DEEP Worldwide.

After losing several good friends to freediver blackout, Dimitris became seriously concerned about this problem. As an author and editor he wrote many articles on freedive safety in an attempt to raise awareness of the risks involved in freediving. As a freediving/spearfishing instructor Dimitris trained more than 200 divers in dive safety and life saving techniques to make them conscious of their need to respect the danger of freediver blackout. Some of those he trained have gone on to become great instructors and spearfishing/freediving record holders. Dimitris is a former member of the Greek National Spearfishing Team, a CMAS freediving instructor, and Judge for AIDA International. Foremost, he is a passionate spearo.
