Technical Training

Have you ever wanted to stay underwater longer, dive deeper, explore inside underwater wrecks and caves, or just expand your scuba diving skills and experience? If so, technical diving may be for you! You can expand your diving opportunities and see things underwater that few divers get to see.

What is technical diving?

Technical diving is planned non-commercial diving that exceeds the recreational diving limits. Technical diving usually involves a ceiling of some sort that does not allow a direct ascent to the surface. This can be a “soft” ceiling where you must complete staged decompression prior to surfacing, or a hard ceiling such as the inside of a cave or wreck. Since a direct ascent to the surface is not possible, technical divers require more equipment, training, and experience than recreational divers.

Who will be my instructor?

Brian Tierney teaches all our technical classes. Brian is an Advanced Trimix Diver, Closed Circuit Rebreather Deco Diver, Advanced Cave Diver, SSI Assistant Instructor Trainer, and TDI Instructor. Brian has been diving for over 30 years, and he has been technical diving and teaching scuba for over 20 years. He holds certifications from GUE, IANTD, TDI, SSI, and PADI.

TDI Course Descriptions

Courses

Intro to Tech

Prerequisites – 25 Logged Dives, AOW diver, and Nitrox certified

Course Overview – This course is designed to provide the AOW diver the opportunity to improve their skills and introduce technical diving equipment and procedures. We will cover equipment configuration and selection, in-depth dive planning, advanced buoyancy control, gas management, situational awareness, and proper trim.

Equipment Required – Single steel tank with H-Valve or Y-Valve, OR doubles with back plate, wing & harness, DIN first stage regulators with 84” & 21” hoses, one stage bottle with DIN regulator & 40” hose, lift bag and spool 

Course Policies – 6 Hours of Classroom and equipment configuration, 3 dives 75 feet maximum depth, 2 days required 

Cost – $395 Includes printed manual, certification fee, quarry entry, and air fills. Additional costs for any equipment rental or Nitrox fills.

Advanced Nitrox

– (Can be combined with Decompression Procedures)

Prerequisites – 25 Logged Dives, AOW diver, and Nitrox certified (Intro to Tech or Technical Sidemount highly recommended) 

Course Overview – Advanced Nitrox picks up where SSI/TDI Nitrox leaves off and offers a more in-depth look at diving with nitrox mixtures up to 100% Oxygen. We will cover physics and physiology relating to diving with gas mixes containing more than 40% oxygen, gas planning, dive tables, dive computers, oxygen limitations, nitrogen limitations, equipment considerations, cylinder labeling, analyzing nitrox mixtures, gas blending procedures, and oxygen service ratings for using gases with more than 40% oxygen.

Equipment Required – Single steel tank with H-Valve or Y-Valve, OR doubles with back plate, wing & harness, OR sidemount harness with 2 independent tanks, DIN regulators with 5’ or 7’ hose, one oxygen clean stage bottle with DIN regulator & 40” hose, lift bag and spool, line cutting device

Course Policies – 6 Hours of Classroom and briefing, 4 dives 75 feet maximum depth, 2 days required

Cost – $495 Includes printed manual, certification fee, quarry entry, and nitrox fills. Additional costs for any equipment rental.
$895 if combined with Decompression Procedures

Decompression Procedures

– (Can be combined with Advanced Nitrox)

Prerequisites – 25 Logged Dives and Advanced Nitrox certified

Course Overview – This course teaches staged decompression diving involving in-water gas switching using oxygen-rich decompression gasses. We will cover decompression dive planning, decompression diving procedures, proper trim, buoyancy and finning techniques, emergency procedures (equipment failures, catastrophic gas loss, omitted decompression, navigational errors, etc.), and equipment considerations.

Equipment Required – Single steel tank with H-Valve or Y-Valve, OR doubles with back plate, wing & harness, OR sidemount harness with 2 independent tanks, DIN regulators with 5’ or 7’ hose, one oxygen clean stage bottle with DIN regulator & 40” hose, lift bag and spool, line cutting device

Course Policies – 6 Hours of Classroom and briefing, 4 dives 150 feet maximum depth, 2 days required

Cost – $595 Includes printed manual, certification fee, quarry entry, and nitrox fills. Additional costs for any equipment rental.
$895 if combined with Advanced Nitrox
