Nora Calloway

Nora Calloway's first open water course nearly ended before it began. She could not equalize, panicked at six meters, and surfaced convinced she was not built for diving. Her instructor did not push. He took her back to the pool, slowed everything down, and spent an hour on breathing and trim before they tried the ocean again.

That experience shaped how she teaches and writes. Over ten years of instructing open water and advanced courses, working on liveaboards, and diving in tropical, temperate, and cold water, Nora has learned that most diving struggles are not about courage or talent. They are about task loading, poor trim, gas anxiety, and instructors who move too fast. With a PADI Open Water Instructor certification and a Rescue Diver background, she writes guides that slow down the parts most courses rush—buoyancy, equalizing, buddy procedures, and dive planning.

Her work covers certification paths, buoyancy and trim, gear selection and maintenance, dive computers, exposure protection, dive travel, liveaboards, shore diving, and marine life. She is particularly interested in the gap between what a certification course covers and what a new diver actually feels on their first ten post-course dives.

When she is not writing or teaching, Nora can usually be found in the pool with a student who is almost—but not quite—hovering motionless, or on a boat explaining why the safety stop is not optional.
