Welcome to our daily lesson in Santo, Vanuatu.

If you think that everything in Technical diving can be fixed with inner tube, zip ties and duct tape, you'll learn about one more thing today.

Richard Pyle, your teacher for this class, will show you how to use aluminium foil.

Do you need to convert an imperial Helium fitting into a metric one? Aluminium foil between the threads

Do you need to avoid that other divers use your trimix bail-out tanks? Aluminium foil on top of the valve

Any other idea? what about reflective patches on your hood? or extra thermal protection?

Tomorrow we'll maybe see how to fix a Cis-Lunar breathing loop with a chewing gum.

Cheers
