TL Sea Diving
From Pacific Northwest local dives to global travel adventures, TL Sea Diving has been changing lives underwater since 1996 — with small classes, passionate instructors, and a family atmosphere that keeps divers coming back.
TL Sea Diving has been serving the Seattle and Tacoma diving community from its shop at 23405 Pacific Hwy S since October 1996, when founders Truxton and Lavonne Terkla combined their love of the sea with a philosophy of genuine customer care — a combination that gave the shop its name. Over 28-plus years, the center has trained thousands of divers from first breath to professional level, consistently emphasizing small class sizes, more time in the water, and thorough, safety-first instruction to internationally recognized standards. Beyond the classroom, TL Sea Diving runs club dives, guided dives, and boat charters for certified divers, as well as dive tour and travel packages for those looking to explore destinations beyond the Pacific Northwest. The shop maintains a full equipment department carrying brands such as Shearwater, Aqua Lung, Apeks, Atomic, DUI, Suunto, TUSA, Ikelite, and Pinnacle, with an equipment gallery, new and rental gear, and a certified repair department servicing regulators, BCDs, drysuits, and tanks. On-site air fills include standard air and Enriched Air Nitrox blends up to 40% oxygen, with aluminum 80s and 100s available for rent to EANx-certified divers. A club membership program keeps the TL Sea Diving community connected and active year-round. Whether a customer needs a gear consultation, an annual service on their regulator, a Nitrox fill, a local dive guide, or help planning an international trip, the shop's experienced team works to cover all aspects of the dive lifestyle in one location.
