The videos above were made during penetration dives into the Spiegel Groves' machinery spaces.
This class is held in Key Largo, Florida. We will penetrate two different wrecks. USCG Duane and USS Spiegel Grove. Max depths will be about 140 feet with several hundred feet of linear penetration into the Spiegel Grove. Shown at the bottom of this page are two videos made during penetration dives into the Spiegel Grove.
This webpage details the minimum content of the Advanced Wreck Specialty. This program is designed for divers who wish to be trained in Advanced Wreck penetration techniques. This skill set would include line laying, deep penetration and advanced wreck diving techniques.
Pre-requisites: Student: DSAT Tec Deep Diver / Tec 45 or equivalent
Maximum Depth: Maximum depth 165 feet
Ratios: Maximum of three students
Min student age: 18
Minimum no. dives:6
Required equipment: Full Tech rig
Lights types and maintenance
Reels types and maintenance
Penetration techniques to include:
Line laying techniques
Hazards to include:
Loss of viz
Loss of gas supply
Separated buddy teams
Local wreck diving regulations
Responsible wreck diving considerations
We will conduct an equipment workshop to review the student’s equipment set up and any specific considerations relating to the wrecks being dived. This should be conducted with the standard technical rig (or sidemount) in mind, along with pre-dive checks. This is also an opportunity to discuss positioning of lights and reels on the students equipment.
Skills to be included:
If the student does not have line laying training (Wreck Specialty or Cavern/Cave training) then these skills will be practiced on land and in open water prior to penetration.
Land based skill development to include:
Deploying a guideline
Technique for following guidel
Use of reel in lost line procedures
Use of line in lost team members procedures
Touch contact communication
Skills to be demonstrated:

Lost line and lost team members techniques
Follow guidelines with no mask / blacked out mask
Air share w/ team member in confined space
Remove / replace mask while in contact with guideline
Demonstrate correct hand and light signals
