Blue Tuna Spearfishing Co

From camo wetsuits and spearguns to NAUI freediving courses that take you 20 meters deep off the Channel Islands — Blue Tuna Spearfishing Co is the one-stop shop for Southern California's breath-hold community.

Blue Tuna Spearfishing Co operates out of Ventura, California, stocking a broad catalog of spearfishing and freediving equipment through their online store. Their own-brand BTS lineup includes camo wetsuits in FishSkin and StoneCrab patterns, anatomical finsocks, gloves, knives, and weight belts, complemented by third-party gear spanning Garmin dive computers, SEAC freediving watches, Rob Allen float systems, and dive lights up to 4,200 lumens. The shop covers everything a spearo or freediver needs, from entry-level starter kits to high-end technical accessories. Beyond retail, Blue Tuna offers NAUI-certified Freediving Level 1 instruction taught from their Ventura base at 2555 E Main Street. The two-day weekend course blends classroom theory, confined-water pool sessions, and open-water dives — students boat out to the Channel Islands to practice constant ballast and free immersion dives to a maximum depth of 20 metres (66 ft). Curriculum covers essential safety and buddy protocols, equalization, static apnea development, and emergency rescue techniques. With small class sizes (reviewers note around five students per session), participants receive highly individualised coaching from experienced NAUI instructors. Course dates run on select weekends from June through September, priced at $569.99 plus a $140 boat fee. Whether the goal is hunting yellowtail and white seabass during pelagic season or simply learning to freedive safely, Blue Tuna positions itself as the full-service resource for the Southern California breath-hold community.
