Discover Scuba vs Open Water: which first?
One is a one-day taster, the other a lifelong certification. Here's the cost of each, what you actually get, and how to choose without wasting money.
If you've never breathed underwater, two options show up first: a Discover Scuba Diving experience (PADI's name; SSI calls it Try Scuba) and the Open Water Diver course. They sound similar but they are completely different products at completely different price points. Choosing wrong can mean paying twice. Here's how to decide.
What a Discover Scuba dive actually is
Discover Scuba (DSD) is a guided taster — not a certification. After a short safety briefing and a few basic skills in shallow water, an instructor takes you on a single supervised dive, usually to around 12 metres. It exists to answer one question: do you even like breathing underwater? You walk away with a memory and a photo, not a card.
Verified DSD pricing
On the Egyptian Red Sea, a Discover Scuba dive typically runs €60–€79 all-in. On Koh Tao it's similar. It's the cheapest, lowest-commitment way to try diving — see current verified prices on our destination pages.
What the Open Water course gives you
Open Water Diver (OWD) is the real thing: 3–4 days of theory, confined-water skills and four open-water training dives. At the end you hold a certification that lets you rent gear, fill tanks and dive with a buddy to 18 metres, anywhere in the world, for life. It costs more — typically several hundred euros all-in — but it's an asset, not an experience.
The money question: does DSD 'count'?
Here's the catch many people miss. A Discover Scuba dive usually does NOT count toward your Open Water certification. So if you're already fairly sure you'll get certified, paying €70 for a taster and then €400 for the course means you've spent €70 you didn't strictly need.
But sometimes the taster is the smart spend
If you have any doubt about whether you'll enjoy diving — claustrophobia, nervousness about breathing underwater, never been in the open sea — €70 is a cheap way to find out before committing several hundred to a multi-day course. Some centers will also credit one DSD dive toward your OWD if you continue with them straight away. Always ask.
A simple decision rule
- Pretty sure you'll love it and want to keep diving? Go straight to Open Water.
- Genuinely unsure, nervous, or just want a holiday experience? Do a Discover Scuba dive first.
- On the fence about cost? Ask the center if a DSD dive can be credited toward the OWD — many will.
- Only have one day? DSD is your only realistic option; OWD needs 3–4 days.
Compare both, all-in
We list Discover Scuba and Open Water prices side by side, both labeled all-in, so you can see the real gap between 'trying it' and 'getting certified' before you decide.
See verified Discover Scuba and Open Water prices on Koh Tao, Makadi Bay and Dahab. And if you decide on the course, our guide on what certification really costs breaks down every line item.
Bottom line: a Discover Scuba dive is a low-cost yes/no test. Open Water is the real certification. If you already know diving is for you, skip the taster and put the money toward the course.
