Compare like with like. A lower figure may describe a pool session, while a higher figure may include a boat and one sea dive. The discover scuba diving price Hong Kong page gives a starting reference. Still, ask for the exact inclusions, date conditions and any optional equipment before paying.
DiveHarbour’s approved planning list records HK$870 per person for TRY-POOL. It records HK$1,020 per person for TRY-BOAT, described as one dive. The list says the instructor, basic equipment, tanks, site or boat arrangements should be confirmed before registration.
Do not compare only the number of dives. Compare total time, travel, briefing, equipment, tank arrangements, boat charges and support. Fees are non-refundable unless the written terms say otherwise. Make-up sessions apply only where those written terms permit them.
Build the total from the same categories for every quote. Include the advertised price, confirmed extras and a reasonable travel allowance. Do not treat an optional camera, meal or transfer as essential value. The fairest comparison describes what you actually plan to use.
