TECHNICAL DIVING

Lynnhaven Dive Center has been offering Technical Dive Training since technical divings’ inception! Our training will get you started on your technical diving adventures. We offer Advanced Nitrox, Deco Procedures, Trimix, Solo Diver, and Sidemount diving courses. Our instructors teach both TDI and SSI courses. We also frequently host John Chatterton, the subject of the best-selling novel Shadow Divers and host of the show Deep Sea Detectives, to teach Advanced Wreck courses. Mr Pete Nawrocky from Get Out and Dive, (Previously with Dive Rite) also hosts Rebreather demonstrations with Optima Rebreather, and can teach Rebreather classes for our students. Never stop learning at LDC!

TDI Solo Diver  This is SDI

  • The first step is to meet the requirements of the course. Solo diving is for divers that have gained a lot of experience already by taking continuing education courses and diving with buddies. Before starting the solo diver course, the diver must: be 21 years old, hold an advanced diver certification and be able to provide proof of 100 logged dives.
  • The next step is to acquire all of the important academic information every solo diver must know. Traditionally, this required attending several hours of formal classroom training. Now, through on-line training, you can complete this phase through self-study, at your own pace, in the convenience of your home or office.
  • The final step is complete your open-water training dives under the supervision of your SDI Solo Instructor. Here you will apply what you have learned during your academic sessions, while learning practical lessons that can only be gained through real-world experience in open water.

TDI Sidemount Diver

 

TDI’s Sidemount Diver specialty is the perfect course for any technical diver wishing to use this increasingly popular equipment configuration, either as a ‘stand-alone’ course or in conjunction with one of TDI’s other open circuit specialties.  It teaches students how to safely utilize side-mounted primary cylinders as an alternative to the traditional back-mounted method.

 

This course takes students through the specific techniques, planning procedures and skills that set side-mounted cylinder diving apart from the traditional back-mounted method.  During the course, the TDI Instructor takes students on a minimum of three dives and covers skills such as:

  • Equipment considerations
  • Gas management
  • Attaching cylinders
  • Trim and buoyancy
  • Deployment of surface marker
  • Different water entries

TDI’s Sidemount Diver Specialty is a useful stand-alone course for the technical diver who wants to become more skilled and proficient with different gear configurations regardless of if he intends to use sidemount all the time.  The course may also be taught in conjunction with any of TDI’s other open circuit specialty courses, on the condition that all prerequisites and standards applicable to both courses are fully met.

 

The maximum depth limit of this course must not exceed that of the student’s current certification, unless being taught in conjunction with another TDI course which allows a greater depth.  Prerequisites to enroll on the TDI Sidemount Diver course are: Age 18, SDI Open Water Diver or equivalent.

SSI/TDI Advance Nitrox Course

The SSI/TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 within your current certification level to a maximum depth of 40 metres/130 feet during dives hat do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. Advanced Nitrox is also a great course for those wanting to extend their bottom times in shallower depths such as scientific diver, and a must for SCR or CCR divers. The course cover topics like

  • Equipment requirements
  • Dive planning
  • Oxygen tracking
  • Blending methods

Certain areas of the world provide spectacular dives at depths deeper than 39m/130 feet but you will not have access (or very limited access) to helium. The SSI/TDI Extended Range course teaches you the proper techniques for utilizing compressed air as a breathing gas and with a maximum depth of 55m/180 feet you won’t have to miss those dives. The Extended Range course will cover topics and skills such as

  • Equipment requirements and configuration
  • Decompression options
  • Use of surface marker buoys
  • Buddy rescue
  • Narcosis checks and management

Materials for this course include the SSI/TDI Extended Range Diving Manual and the US Navy or Buhlmann Air Decompression Tables (made of vinyl for easy in-water use and storage)

SSI/TDI Deco Procedures

 

As sport divers planned decompression is not something that we do or have been taught. The SSI/TDI Decompression Procedures course prepares you for planned staged decompression diving. With a maximum operating depth of 45m/150 feet, this course is your first step beyond the normal sport diving limits. Your Instructor will provide you with valuable information and skills, among the topics covered are

  • Kit set-up
  • Equipment requirements
  • Decompression techniques
  • Decompression breathing gases
  • Gas management
  • Contingency planning
  • Problem solving procedures

The SSI/TDI Decompressions Procedures course combined with the SSI/TDI Advanced Nitrox course form the foundation of all other technical courses.  After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.

Some of the materials you will be using include the SSI/TDI Divers Guide to Decompression Procedures, US Navy or Buhlmann Air Decompression Tables (made of vinyl for easy in-water use and storage)

SSI/TDI Trimix Diver

As your motivation to explore progresses you will find that you may want to go deeper to dive that wreck that is part of history or that cave system that you have read so much about.  One of the major limiting factors of going deeper is narcosis; SSI/TDI’s Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. While taking the Trimix Diver course your SSI/TDI Instructor will teach you how to plan and execute dives utilizing as little as 18 percent oxygen and diving to maximum depth of 60 m/200 feet with a blend of helium appropriate for the planned depth. The course covers topics and skills like

  • Dive team planning
  • Gas matching
  • Cylinder labeling
  • Surface marker deployment
  • Equipment configuration
  • Thermal protection options

Rebreather Demo

-LDC also host Rebreather Demonstrations with Pete Nawrocky from Dive Rite on the Optima Rebreather.

TDI Advanced Wreck
