The diving certification ladder looks longer than it is, partly because agencies have a commercial interest in it looking that way.

Here is the whole thing, with an honest note on each rung about whether you actually need it.

The bolded rows are the ones we would push. The rest depend on you.

Starting out

Try Scuba / Discover Scuba

One supervised dive in shallow water, under direct professional supervision, within agency depth limits. Not a certification. Takes a morning.

Who it's for: anyone unsure whether they will enjoy being underwater, and anyone nervous. It is also simply a good thing to do on a holiday.

Who can skip it: people who already know they want to certify. It is not a prerequisite.

Full detail: try scuba in Beirut.

Open Water Diver

The real qualification. Theory, confined-water skills, open-water training dives. Three to four days. Does not expire. Recognised worldwide.

After it you can rent gear and dive with a buddy anywhere. Everything else in this article is optional; this is not.

The two that actually matter next

Advanced

Usually five dives across different specialty areas, including a deep dive and a navigation dive. Short — often a weekend.

Why it matters in Lebanon specifically: the country's best diving is at 30–40 metres. The Souffleur, Shark Point, the Batroun wrecks and much of the Alice B sit outside entry-level limits. Without advanced training, a large part of Lebanese diving is closed to you.

When to do it: after twenty or so relaxed dives, not the week after certifying. The course is more valuable to a diver who has some water time.

Enriched air nitrox

A short course — theory plus practical gas analysis, often no dives required.

Why it matters here: on 35–40 metre wrecks, particularly on a two-dive day, nitrox meaningfully reduces your nitrogen loading. It does not let you go deeper. It gives you a better second dive and a more conservative day.

Of all the short courses, this is the one with the best ratio of cost to actual benefit on this coast.

Specialties worth considering in Lebanon

Deep. Formal training for the 30–40 metre range where Lebanon's good diving lives.

Wreck. Only if you want to go inside. Diving around the outside of a wreck does not require it; penetration absolutely does. Why the distinction matters.

Navigation. Underrated. Useful on every dive, everywhere, forever.

Night. The same site becomes a different place. Worth doing once even if you never repeat it.

Perfect buoyancy / peak performance buoyancy. The least glamorous course on any agency's list and quite possibly the most useful.

Specialties that may not be worth it here

Be honest about your diving before buying these.

Dry suit. Rarely relevant in Lebanese water temperatures.

Altitude. Not applicable to sea diving.

Ice, cave, sidemount and similar. Either not available locally or serving a kind of diving you are unlikely to do on this coast. Do them where they are relevant.

Rescue Diver — the one people underrate

Almost every experienced diver, asked which course changed them most, says Rescue.

It is not about heroics. It is about recognising a problem early — the diver who is breathing fast, the buddy who has drifted, the person on the boat who has gone quiet — and dealing with it before it becomes serious.

It also changes how you dive. Rescue-trained divers watch the group differently, and they become the person others want to dive with.

Going professional

Divemaster is the first professional grade — guiding certified divers, assisting instructors. It requires substantial logged experience and is a real commitment, measured in months rather than days.

Instructor is a career decision.

Both are worth doing for the right person and a waste for someone collecting certifications. The honest version is in going pro in Lebanon.

A realistic first two years

TimeframeWhat to do
Month 1Try dive, then Open Water
Months 2–820–30 dives. Different sites, different conditions
Month 9Advanced + nitrox
Months 10–18Another 30 dives, including the deeper wrecks
Month 18+Rescue, and specialties you have identified a need for

That sequence produces a genuinely capable diver. The compressed version — five certifications in three months, forty logged dives total — produces someone with a lot of cards who is still not comfortable at thirty metres.

What it all costs

Prices vary by centre and move over time. The components of a real quote, and the questions that reveal a suspiciously cheap one, are in what diving actually costs in Lebanon.

Ask SEALS for current pricing on any of the above.
