How we rank
Every shop gets a score out of 100 from six criteria. The weights and the data behind each score are shown on every entry, and the full table can be downloaded as CSV. Scores are recalculated whenever the data changes; this page was last updated on 2 May 2026.
| Criterion | Weight | What we measure |
|---|---|---|
| Verified reviews | 30 | Google rating and review count, shrunk toward the destination average so a 4.9 with 30 reviews does not beat a 4.8 with 1,500. |
| Safety & quality signals | 25 | Maximum students per instructor (the single biggest safety lever on a course), years in operation, multi-agency status, instructor-level training centre, nitrox on site. |
| Price transparency & value | 15 | Published Open Water price (or fun-dive price where courses are not the main product) against the destination median. Cheapest is not always best; transparency is rewarded, hidden fees are not. |
| Offering breadth | 10 | Agencies offered, languages spoken, range of products, and whether technical, liveaboard or nitrox diving is available. |
| Sustainability | 10 | Green Fins membership or a documented conservation programme scores full; a mention without evidence scores half. |
| Editorial visit | 10 | Full marks when our team has visited the shop and verified boats, gear room and classroom in person. Half when the shop has confirmed its data with us. |
Rules
- Paid listings and partnerships never affect the score, and are labelled where they appear.
- Missing data scores zero. It is the shop's data to provide; we do not guess.
- A shop can dispute any data point. Corrections are applied and dated.
- Review data is pulled from Google and dated; we do not collect our own reviews yet.
