SCUBA & Inland

Watch: SCUBA Dive Training – Alki Lake, Seattle

This course is exciting because it’s never quite the same. Practical skills are gained by diving in a variety of locations around Seattle. You’ll learn SCUBA and get certifications, as well as learning NDT, or non-destructive testing.

“Every day be ready for something different. Be on time and be ready for anything.”
- Mike Hemion, Instructor

You’ll gain experience with practical applications off campus. Instructors plan a variety of projects throughout Seattle and in the Puget Sound. A few examples include: video inspections on a pier, visually inspecting the bottom of a boat in the water, removing obstructions from a boat’s propeller, or changing the buoyancy of a dock.

You’ll learn about safety in different conditions, and how tides affect different locations. Students practice diving in the Puget Sound, which is tidal. You’ll gain first hand experience learning how to plan ahead and dive successfully in water that is ebbing or flooding.


In addition to all the SCUBA gear, you’ll learn how to use NDT tools, such as Magnetic Particle gauges and thickness gauges. The thickness gauges uses sound waves to test the thickness of metal. It can be used with only one side of the metal. Magnetic Particle testing uses a dye that can be squirted on a piece of metal, and will cause any cracks to glow.

Instructor Insight

Mike's Answer:

“They learn about different locations, how tides can change things. If we go to the Sound, we might have a different entry and exit point. At school here all the barges are the same, the water level stays the same, there's no surf or surge. When we're off campus sometimes, I tell them they can't tie up a ladder on a location, they don't really get it and every now and then somebody will tie up a ladder and then when the tide drops their ladder breaks in half because the bottoms not moving but the float that we are on is moving up and down. And there's pilings that float up and down and their air hose can get stuck on that if they're not being careful.  They learn more about what they've heard about in the classroom but they see it in real life. They see the dive site actually changing between 8 in the morning and 1 in the afternoon. Everything can be completely different.”

Mike's Answer:

“I’d say the first day that we go into the Sound. Because even the certified SCUBA divers, even they might not have dove in the Puget Sound. The first day of diving in salt water is the funnest.”

“Every day be ready for something different. Be on time and be ready for anything.”
