A dive torch is an essential tool for underwater exploration. Whether you’re diving at night, exploring shipwrecks, or descending into deeper water, a good torch enhances visibility and safety. Designed specifically for underwater use, dive torches are built to handle pressure, resist water, and provide powerful illumination where natural light fades.
For both recreational and technical divers, having a reliable dive torch can make all the difference between a routine dive and an extraordinary one.
What is a Dive Torch?
A dive torch is a waterproof, high-powered flashlight designed for use underwater. Unlike regular torches, dive torches are built to withstand high pressure at depth and to operate reliably in wet, cold, and low-light environments.
Their main purpose is to provide clear visibility in dark or murky water, illuminate marine life, and enhance safety by helping divers see their surroundings—and each other—clearly.

Why is a Dive Torch Important?
Night Diving
When diving at night, a torch is your primary source of light. It helps you navigate, communicate with your buddy, and spot nocturnal marine life that’s often hidden during the day.
Cave and Wreck Diving
Dive torches are vital in environments where natural light is limited or non-existent. Exploring caves, wrecks, or overhangs without one would be nearly impossible.
Deep Diving
As you descend, sunlight diminishes and colours begin to fade. A torch restores colour and detail, revealing the full beauty of the underwater world.
How Does a Dive Torch Work?
Dive torches are specially sealed with O-rings to keep water out and are rated to specific depths. They typically use LED bulbs for bright, energy-efficient light and are powered by either rechargeable or replaceable batteries.
The design is rugged and often features grip-friendly handles or lanyards for secure handling underwater.
Types of Dive Torches
Primary Dive Torch
Larger and brighter, used as your main light source on night or deep dives.
Backup Dive Torch
Smaller and more compact, kept in reserve in case your primary torch fails.
Canister Dive Torch
Used by technical divers, these have an external battery pack and offer extended burn time and brightness.
Key Features to Consider When Choosing a Dive Torch
Brightness (Lumens)
The higher the lumen count, the brighter the torch. For night or wreck dives, aim for 1,000 lumens or more. For shallow or daytime dives, 500–800 lumens may be sufficient.
Beam Angle
- Narrow Beams (Spotlights): Great for caves, wrecks, or signalling.
- Wide Beams (Floodlights): Better for general visibility and video work.
Battery Life and Type
Choose a torch with long battery life, especially if you’re doing multiple dives. Rechargeable options are eco-friendly and cost-effective long term.
Depth Rating
Always check how deep the torch is rated to go. Recreational torches are typically rated to 100–150 metres.

How to Use and Maintain a Dive Torch
Before Your Dive
- Charge or replace batteries.
- Inspect and lubricate O-rings.
- Ensure the torch is securely sealed.
After Your Dive
- Rinse the torch with fresh water.
- Dry and store it in a cool, dry place.
- Check seals and batteries regularly.
Conclusion
A dive torch is more than just a light—it’s a vital piece of safety equipment and an essential tool for discovering the underwater world. From night dives to deep explorations, having the right torch helps you see more, stay safe, and make the most of your dive.
When choosing your next torch, consider the type of diving you’ll do and invest in a torch that’s durable, powerful, and built for your needs.
