Our Instructors

Arthur W. “Rusty” Myers III | The OG (Old Guy)
SDI Elite Instructor • SDI and ERDI Instructor

Rusty commanded the Charleston Police Department Dive Team for approximately seven years and has spent years diving, training, and helping others become comfortable underwater. He holds more than 50 certifications across SDI, TDI, and ERDI, including SDI and ERDI instructor credentials, and is now an SDI Elite Instructor. He has owned and taught through Blue Line Scuba since 2015. He also teaches with Beyond the Bouy, the advanced diving company linked here.

His background includes public safety diving, swiftwater rescue, and first aid instruction. More than three decades in law enforcement have reinforced the importance of preparation, clear communication, and looking after the people beside you. Those lessons belong underwater, too.

At Blue Line Scuba, his goal is to help students build sound skills, confidence, and good judgment. A certification is a beginning. There is always more to learn, and that includes the instructor. The underwater world is an amazing one!

Outside diving, he serves as Deputy Chief of Police at a state university and teaches leadership and ethics in addition to Active aggressor response and other related police topics. He is also the author of Tattered: When the Blue Line Frays, a memoir about survival, leadership, and the road back, and Confession of Justus, a historical fiction novel. Teaching and writing give him different ways to do the same thing: share what he has learned so someone else can benefit from it.

Rusty is a husband, father of two grown children, and a lifelong student. You can usually spot him underwater by his yellow fins. Greybeard wears white. They make that part easy!

Dive safe. Dive often. Keep learning.

Brooks “Greybeard” Harvey | Greybeard the Bouyant
SDI Instructor

Brooks has been diving for more than 20 years and became an instructor in 2025. Teaching gives him the opportunity to share that experience and help others discover what has kept him coming back to the water for two decades.

He also served as a deputy sheriff for several years. His background combines public service with a practical, hands-on approach to getting things done.

He is a jack of all trades. He enjoys figuring things out, fixing what needs attention, and getting the job done. That practical approach carries into diving, where preparation, equipment, and attention to detail matter.

At Blue Line Scuba, his goal is to help students build their skills, gain confidence, and enjoy their time underwater. There is always something more to learn, even after 20 years.

He runs Blue Line Fills. He fills scuba tanks, does visual inspections, services regulators and handles hydro testing for the local dive community. Need air? Give him a call.

You can spot him underwater by his white fins and, of course, the beard. Rusty wears yellow. They make that part easy.

Dive safe. Dive often. Keep learning. Grow a beard.

James Comfort | Scuba Squirrel
Dive Instructor • Technical Diver • Public Safety Diver

James has spent more than a decade in public safety diving, including many years on the Charleston County Sheriff’s Office Dive Team. He has been a dive instructor for five years and continues to expand his own training through rebreather and advanced scuba diving. His technical diving experience includes dives beyond 300 feet, where preparation, discipline, and sound judgment are essential.

He owns Beyond the Bouy and teaches many of Blue Line Scuba’s advanced and technical diving classes through that business. He enjoys helping students develop the skills and understanding they need as their diving becomes more demanding. Each new level of training builds on the fundamentals.

He still serves in law enforcement as a police officer and the Training Sergeant for his department. Teaching officers and teaching divers share a common responsibility: preparing people to make good decisions when conditions are challenging. He brings new ideas and training to both groups while continuing to learn himself.

Outside diving, he is an avid ham radio operator and enjoys working with electronics. He is also a precision marksman and long-range rifle shooter. Whether he is working on radio equipment, refining a shot, or planning a technical dive, he enjoys the attention to detail each requires.

At Blue Line Scuba and Beyond the Bouy, his goal is to share that experience and help students become capable, thoughtful divers. There is always another skill to practice and something new to learn.

Dive safe. Dive often. Keep.... oh shiny...

The Blue Line Scuba Mission

Blue Line Scuba exists to develop safe, confident, capable divers through practical training, clear instruction, and real-world experience.

We believe good dive training is more than completing skills and earning a certification card. Our job is to teach people to think, solve problems, understand their equipment, respect the environment they are entering, and take care of themselves and the divers around them.

Our instructors bring decades of experience from recreational diving, public safety, law enforcement, fire, EMS, technical diving, and military service. We use that experience to prepare our students for the dive they are actually going to make, not simply the minimum required to pass a course.

Whether someone is taking their first breath underwater, advancing their recreational skills, entering technical diving, or preparing for public safety operations, our goal remains the same:

Train hard. Dive smart. Take care of your people. Come home safe.

In Memoriam

If you ever met Scott, our assitant instructor, you know this image captures him in a special way. Scott was a cancer survivor who lived thirteen years after beating stage four cancer. We believe it was just out of spite to prove his doctors wrong! We lost Scott in 2025 when the cancer returned with a vengeance. If you ever dive the USS Spiegel Grove in Florida, you can visit him at the American Flag. We miss him! From the angry face, to his favorite phrase (Bite Me) to his favorite hand signal, this was Scott.

Also, the silt. Lots of silt...

His buoyancy (or lack thereof) was famous.

We miss you old man!!!
