A useful enquiry is short, specific, and honest. Start with your current highest certification and agency. Add your logged dives, recent dive date, rescue and first-aid status, and target role.
State whether you want to teach beginners, guide certified divers, or compare both. Mention your preferred month and available practice days. Include the environments you know and the environments you need to practise.
Ask five direct questions. Which prerequisites apply? Which activities are supervised? What evidence must you bring? What does the fee include? What happens if an evaluation needs repeating? Written answers reduce avoidable surprises.
A good brief could say: “I am a rescue-level diver with 58 logged dives. I want to compare teaching support with certified-diver leadership. I can practise on weekends. Please review my records and suggest the next supervised gate.”
Do not promise clients, employment, or independent teaching before the relevant rating and active status are confirmed. Use the conversation to test fit. The best route is the one you can perform responsibly and explain clearly.
DiveHarbour can discuss current Hong Kong arrangements and help organise your questions. The training centre and agency must confirm the applicable standard. Medical fitness belongs with an appropriately qualified physician.
