Level 1 Freediver

Instructor: Zachary Small

HIGHLY RECOMMEND this INCREDIBLE COURSE to anyone interested in Freediving. Zachary Small is SUPER KNOWLEDGEABLE and a terrific instructor. I've been spearfishing and snorkeling for years but this course took things to another level. My wife and I now have the knowledge we need to be SAFER IN THE WATER and more effective at spearing and lobstering. Well worth every penny of the price! TWO THUMBS UP!! Don't hesitate - get certified! Thanks to Zach and Hypoxic Hunters - Fort Laudedale, FL. See you under the water!!
