📸 The Ultimate Action Camera Buying Guide for Scuba Divers
🎥 How to choose the right underwater camera — from DJI to GoPro, SeaLife and more
Underwater video has never been easier — or more exciting. Today’s compact action cameras allow divers to capture moments that once required bulky housings and professional rigs. Whether you’re drifting over coral gardens, filming a manta ray sweeping past the reef, or zooming in on the mesmerizing behaviour of a tiny nudibranch, a small, travel-friendly camera can preserve memories with stunning clarity.
But while action cameras have improved dramatically, the underwater world is a uniquely challenging environment. Light disappears quickly, colours shift, currents shake your footage, and depth limits rapidly separate the good from the great. The action camera that works perfectly for hiking or mountain biking might struggle the moment you descend past 10 metres.
In other words: not all action cameras are created equal — especially for scuba diving.
This guide is here to simplify the process. We’ll walk through what divers should prioritise in a camera, break down the most important features for underwater use, and compare today’s top models — including the DJI Osmo Action 5, GoPro HERO series, Insta360, Akaso, and dedicated underwater systems like SeaLife.
Whether you're a new diver capturing your first reef scenes or a seasoned photographer looking for a reliable backup camera, this guide will help you choose a setup that fits your style, your budget, and the way you dive.
Let’s dive in.
🌊 What Makes a Great Action Camera for Scuba Diving?
Before diving into specific models, it’s important to understand the features that genuinely matter underwater. Action cameras behave very differently at depth — low light, colour loss, movement, and pressure all place unique demands on your gear. The specs printed on the box often don’t tell the full story.

Below are the features that truly make a difference once you submerge.
1️⃣ Depth Rating & Housing
Most action cameras are only waterproof for surface use or shallow snorkeling — typically 5–10 metres. That’s nowhere near enough for scuba diving, especially in places like Southeast Asia where dives regularly reach 18–30 metres.
To safely take your camera underwater, you need:
A dedicated housing rated to 30–60 m
Reliable O-rings that create a watertight seal
A secure locking mechanism that won’t pop open under pressure
Large, tactile buttons that work with gloves
Compatibility with trays, filters, and lights
Think of your housing as insurance. It protects both your footage and your investment. Even the best camera will fail if the housing fogs, leaks, or flexes under pressure.
2️⃣ Video Quality & Colour Performance
The underwater world is breathtaking — but cameras struggle to capture it without help. Water absorbs light differently than air:
Red goes first (loss starts around 5 metres)
Then orange
Then yellow
Contrast disappears
Everything shifts blue/green
To counter this, a great dive camera should offer:
4K (or higher) resolution for sharpness and cropping flexibility
Strong colour rendering or a dedicated underwater mode
High frame rates (60–120fps) for smooth motion and slow-motion shots
Good low-light handling to prevent grainy footage
Compatibility with red filters or video lights to restore natural colour
These features transform flat, washed-out footage into vibrant, cinematic scenes that actually match what your eyes see underwater.
3️⃣ Image Stabilization
Even the calmest dive includes movement:
gentle fin kicks
surge
drift currents
your own breathing
All of this creates shake.
High-quality stabilization is essential for underwater video. The best cameras use advanced algorithms to deliver:
horizon leveling
gimbal-like smoothness
reduced warping at the edges
Without stabilization, your footage will look chaotic, especially during drift dives or when filming fast-moving subjects like cuttlefish or trevallies.
4️⃣ Low-Light Capability
Underwater, it’s always low light — even at midday.
A great action camera needs to handle:
deeper reef sections
inside wrecks
caves and overhangs
cloudy conditions
early-morning and late-afternoon dives
Look for:
larger sensors
good dynamic range
clean noise performance
These qualities help preserve detail and colour where cheaper cameras simply produce grainy, muddy footage.
5️⃣ Accessory Support
As you grow as a diver and videographer, your camera should grow with you.
Look for systems that support:
video lights (the #1 upgrade for underwater footage)
colour filters
wide-angle or macro wet lenses
mounting trays for stability
dual-handle rigs for balanced shooting
A camera with strong accessory compatibility will take you from casual holiday footage to professional-level cinematics.
6️⃣ Ease of Use Underwater
Underwater photography is never just about the camera — it’s about staying safe while capturing the moment. Your device must be:
simple to operate with minimal menu-diving
equipped with large, easy-to-press buttons through the housing
visible even in bright tropical sun or low light
capable of switching modes quickly (photo → video → slow motion)
When buoyancy, depth, buddy communication, and environmental awareness all come first, your camera should support you — not distract you.

🔦 🔧 Pro Tips for Underwater Video Success
Getting amazing underwater video isn’t just about the camera you choose — it’s how you use it. These tips will help you get smoother, clearer, more colourful footage on every dive.
✔️ 1. Add a Video Light or Red Filter
Water strips out red, orange, and yellow tones quickly.
A light restores color at depth, while a red filter helps correct the blue/green cast.
✔️ 2. Get Close to Your Subject
Stay within 1–2 metres for the best clarity and color.
The further away you are, the more washed-out and hazy your footage will look.
✔️ 3. Slow Down and Control Your Buoyancy
Good buoyancy equals smooth footage.
Hover, move slowly, and avoid fin kicks that cause sudden camera shake.
✔️ 4. Use Two Hands or a Tray
A tray or dual-handle rig creates stability and reduces wobble in currents, surge, or drift dives.
✔️ 5. Shoot Upward When Possible
Angle your camera slightly upward toward blue water.
This adds contrast, highlights marine life, and creates more cinematic shots.
✔️ 6. Use Higher Frame Rates for Action
60fps or 120fps helps capture fast-moving fish, trevally hunts, or turtles cruising past.
✔️ 7. Practice Before Your Trip
Familiarity matters.
Learn how to switch modes, adjust settings, and operate the housing before reaching the dive site.
✔️ 8. Think in Short Clips
Shoot 5–10 second clips instead of long, continuous shots.
This gives you more variety and easier editing later.
✔️ 9. Keep Your Lens and Port Clean
Fogging or smudges ruin footage.
Use anti-fog inserts, keep O-rings clean, and check the lens before every entry.
✔️ 10. Enjoy the Dive
Some of the best moments happen when you’re relaxed and present.
Capture what you can — but experience the dive first.
💬 Final Thoughts
Underwater videography has never been more accessible, and today’s action cameras make it possible for divers of every experience level to bring home incredible memories. Whether you’re filming a manta ray gliding overhead, capturing the neon colours of a coral garden, or documenting macro critters hiding among the reef, the right camera setup turns every dive into a story you can relive again and again.
The best camera isn’t always the most expensive one — it’s the one that fits your style, your budget, and the type of diving you love. The DJI Osmo Action 5 excels as the all-round champion, GoPro offers unmatched accessory support, Insta360 delivers creative possibilities, SeaLife provides underwater-specific reliability, and budget cameras make underwater video accessible to everyone.
Most importantly, remember that great footage starts with great diving skills: buoyancy, awareness, and slowing down enough to let the ocean reveal its magic.
Choose a camera that inspires you, build a simple setup that works for your dives, and enjoy the process of capturing the underwater world — one clip at a time.
