Freediving vs Scuba Diving: Which Should You Learn?

Looking for more gear recommendations?

Both involve going underwater. That's roughly where the similarities end. Scuba diving and freediving are genuinely different sports that attract different types of people, require different equipment, and feel completely different in practice.

This guide covers the key differences, what each involves, and which you should learn first — particularly for UK conditions.

The Core Difference

Scuba diving: You carry a tank of compressed air (or nitrox). A regulator reduces the pressure to breathable levels. You can breathe continuously at depth for as long as your gas supply lasts.

Freediving: No equipment. You hold your breath, dive to depth, and return to the surface on a single breath. The absence of bubbles, tank, and regulator changes the experience entirely.

This difference cascades into everything — equipment cost, training approach, community culture, and what the activity actually feels like.

Equipment

Scuba

Freediving

Freediving is significantly cheaper to get into. The equipment is also less bulky — a freediver in a wetsuit with a long fins and a mask is carrying perhaps 5kg of gear. A scuba diver is managing 20-30kg.

Depth and Time

Recreational scuba diving: 18-40m (max recreational limit is 40m). Dive time 30-60 minutes at recreational depths. No breath-hold required.

Recreational freediving: 10-20m for most people starting out. Dive time 1-3 minutes per dive. With training, progressing to 25-40m and longer breath holds is achievable.

Competitive freedivers reach 200m+ and hold their breath for 10+ minutes. Those numbers are irrelevant to recreational diving, but they illustrate the ceiling.

For extended time at depth without physical exertion, scuba is the better tool. For brief, frequent dives and a different relationship with the water, freediving delivers something scuba can't.

Both routes are accessible and neither is technically hard at entry level. Scuba has more admin (kit checks, gas fills, buddy system protocols). Freediving requires more consistent physical practice to progress.

The UK Context

UK conditions suit both disciplines, but differently.

Scuba in UK waters is world-class — wrecks, reefs, seal encounters, dramatic kelp forests. Cold water (6-16°C) requires a drysuit or 7mm wetsuit. Sites like St Abbs, Lundy Island, the Farne Islands, and Plymouth Sound are renowned internationally.

Freediving in UK waters is possible but less common as a standalone practice. Quarry diving (Capernwray in Lancashire, Wraysbury in the South East) is popular for training in controlled conditions. Open sea freediving happens at sheltered bays in Cornwall and Wales. The cold water is manageable in a well-fitted wetsuit.

Most UK freedivers use indoor pools for technique work and quarries for depth progression, rather than the open sea year-round.

Which Should You Learn First?

Learn scuba first if: You want extended time underwater, you're primarily interested in UK wrecks and reefs, or you want to dive with an established club (BSAC has clubs throughout the UK).

Learn freediving first if: You're a strong swimmer, you're more interested in the physical and mental challenge, you want to start diving cheaply, or you're already attracted to free diving as its own discipline.

The honest answer: Most people find scuba easier to start with because the tank removes the breath-hold challenge, letting you focus on buoyancy and navigation. Freediving demands more from you upfront. But once you've mastered breath-hold technique, freediving feels more intimate and less encumbered.

Many UK divers eventually do both. The skills transfer well — freedivers develop better buoyancy awareness, scuba divers bring site familiarity and safety habits.

Safety Note

One firm rule if you do both: never freedive within 12 hours of scuba diving. Residual nitrogen from scuba diving significantly increases decompression risk if you freedive shortly after. Most guidelines recommend 24 hours.
