Kids' scuba courses cost: Bubblemaker, Seal Team and Junior Open Water
From pool bubbles at eight to a real Junior Open Water card, here's how kids' scuba courses work, the age and depth limits that apply, and what they cost.
Children can start scuba younger than most parents expect — but the courses are deliberately staged by age, with shallow depth limits and close supervision built in. This guide walks through the three main steps most agencies offer: Bubblemaker, Seal Team (or Aquamission-style programs), and Junior Open Water. It covers the minimum ages, the depth limits, what each one actually involves, and what to budget in 2026. It's general education to help you plan, not medical advice — every child should be cleared as fit to dive before any in-water program.
Bubblemaker — first bubbles, from age 8
Bubblemaker is a gentle pool or confined-water taster, usually from age eight. Kids breathe underwater for the first time in shallow water — typically no deeper than around two metres — with an instructor right alongside. It's not a certification; it's a fun introduction designed to see whether a child enjoys breathing underwater at all, with minimal pressure and maximum supervision.
Seal Team — skills and missions, from age 8
Seal Team (and similar agency programs) builds on Bubblemaker with a series of pool 'AquaMissions': basic skills plus fun specialty-style missions like buoyancy, navigation and night-diving games, all in the pool. It keeps young divers engaged across several sessions and is a natural bridge between a one-off taster and a real entry-level course.
Junior Open Water — a real certification, from age 10
Junior Open Water is the real thing: the same entry-level course adults take, certified from age ten, but with reduced depth limits and a requirement to dive with a parent, guardian or qualified professional. Younger juniors (around 10–11) are usually limited to about 12 metres; older juniors (around 12–14) to around 18 metres. The card converts to a standard Open Water certification once the diver reaches 15.
Age and depth limits at a glance
Bubblemaker from ~8 (pool, ~2 m, not a certification). Junior Open Water from ~10, limited to ~12 m for ages 10–11 and ~18 m for ages 12–14, always diving with a parent, guardian or pro. Limits relax to adult levels at 15. Exact rules vary slightly by agency — confirm locally.
Typical cost
Tasters are cheap; the full Junior Open Water sits close to the adult Open Water price because it's essentially the same course with extra supervision. Location drives price as always, and family or sibling bookings sometimes earn a discount.
| Bubblemaker (pool taster) | €40–€90 |
| Seal Team / AquaMission program | €100–€220 |
| Junior Open Water (budget hubs) | €250–€380 |
| Junior Open Water (Western Europe) | €350–€550 |
| Plan a taster | €40–€220 |
A taster first is the smart move
Before paying for a full Junior Open Water, a Bubblemaker session tells you cheaply whether your child genuinely enjoys breathing underwater. Some kids love it instantly; others would rather snorkel. Spending €60 to find out beats committing to a multi-day course on a guess.
What parents should check
- Fitness to dive — children should be medically cleared, just like adults.
- The center's instructor-to-child ratio; smaller groups mean closer supervision.
- Whether a parent needs to be certified too, so juniors can dive with you.
- That depth limits match your child's age band and aren't quietly exceeded.
The DiveCost take
Kids' scuba is staged this way for good reasons — keep it fun and pressure-free at the early ages, and don't rush a nervous child into a full course. Start with a taster, watch whether they ask to go again, and only then commit to Junior Open Water. The depth limits aren't red tape; they're the safety margin that makes early diving sensible.

Bottom line: kids can start with pool bubbles around eight and earn a real Junior Open Water card from ten, within sensible depth limits. Start with a cheap taster, make sure they're cleared and keen, and let their enthusiasm — not the calendar — set the pace.
