Nothing here is a separate chore. The things that make a site profile worth reading are fields on the log entry you were filling in anyway; sharing is what happens when you don't keep them to yourself.
Anyone can add a dive site: where it is, how you get in, what's down there, what to watch for. Free on Basic — a database built by divers can't have a paywall on the building.
Visibility, conditions, and how the dive went, recorded on the entry you were already filling in. One diver's Saturday is the next diver's forecast sanity check.
Marine life logged per dive, per site, with dates — which is what makes "is the octopus still there?" a question with an answer instead of a forum thread.
Pictures from the dive and notes on the site's page, so the profile is what divers who've been there say it is, not scraped copy from a shop's website.
A shoreline that looks right on the chart, a rumour from the shop, a wreck someone mentioned once. Post it as a lead, and it becomes an open question the community can go answer.
Drop a lead on a location you think holds a dive. It goes on the map as an uncharted spot — not a site yet, an open question with your name on it.
Another diver claims the lead, dives it, and brings back what's actually there — access, depth, hazards, whether it's worth the drive at all.
Claimed leads go under review before they become a published site. If something's missing it comes back with the reason attached and stays claimed — the work isn't thrown away, it's returned with notes.
This is the return on contributing, and it's worth being precise about: none of these layers is bought data or a partner feed. Each one is a rendering of what divers recorded.
Sites where creatures have been spotted in the last 30 days — straight off logged marine life.
A heatmap of where diving actually happens, built from logged dives.
Average recent visibility per site, from the viz divers recorded on their entries.
A heatmap weighted by community likes — where divers keep going back.
Which sites have community photos, with counts and thumbnails.
Scored dive windows drawn on the map, on the sites the community put there.
The map itself is free. These six overlays are an Advanced feature — the data in them is not, and never gets taken away from the divers who put it there.
Every entry carries its own visibility — public, private, or shared with specific people. A dive you keep private stays private, and a site you'd rather not broadcast can be a private site on Advanced. Nothing is published on your behalf.
Send a site to one diver or a whole group, view-only or open to comments, and tag the buddies you dove with so it lands in their log too. Not everything worth sharing needs to go to everyone.
Creating dive sites and logging dives is free, with no card. The next diver there is counting on someone having gone first.
